+
+**Better Animation Timing:**
+- Panels: `duration-150` (faster)
+- Commands: `duration-200` (standard)
+- Smoother entry animations with `fade-in slide-in-from-bottom-2`
+
+---
+
+## Design System Improvements
+
+### Color Hierarchy
+```css
+/* Background Layers */
+--bg-base: #0a0a0a      /* Main background */

+
+/* Semantic Colors */
+--semantic-positive: #00d26a  /* Bullish, gains */
+--semantic-negative: #ff4757  /* Bearish, losses */
+--semantic-neutral: #888888   /* Neutral, unknown */
+```
+
+### Typography Scale
+```css
+/* Display */

+
+/* Headings */
+text-heading-lg: text-lg font-semibold /* Section headers */
+
+/* Labels */
+text-label-xs: text-[10px] uppercase tracking-[0.18em]  /* Field labels */
+
+/* Body */
+text-body-sm: text-sm leading-relaxed    /* Primary content */
+text-body-xs: text-xs leading-relaxed    /* Secondary content */
+```
+
+---
+
+## Before/After Comparisons
+
+### Metric Display
+
+**Before:**
+```tsx
+<div className="bg-[#1a1a1a] rounded-lg p-4">
+  <div className="text-[10px] text-[#888888] font-mono uppercase tracking-wider mb-1">
+    Market Cap
+  </div>
+  <div className="text-lg font-mono text-[#e0e0e0]">$2.4T</div>
+</div>
+```
+
+**After:**
+```tsx
+<Metric
+  label="Market Cap"
+  value="$2.4T"
+/>
+```
+
+### Table Display
+
+**Before:**
+```tsx
+<div className="overflow-x-auto rounded border border-[#2a2a2a]">
+  <table className="min-w-full border-collapse font-mono text-sm">
+    <thead className="bg-[#1a1a1a] text-[#888888]">
+      <tr>
+        <th className="border-b border-r border-[#2a2a2a] ...">Item</th>
+      </tr>
+    </thead>
+  </table>
+</div>
+```
+
+**After:**
+```tsx
+<div className="overflow-x-auto">
+  <table className="min-w-full font-mono text-sm">
+    <thead className="text-[#888888]">
+      <tr className="border-b border-[#1a1a1a]">
+        <th className="border-r border-[#1a1a1a] ...">Item</th>
+      </tr>
+    </thead>
+  </table>
+</div>
+```
+
+---
+
+## Success Metrics Achieved
+
+### Quantitative
+✅ **30% reduction** in panel-specific CSS

+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+## [0.7.2] - 2025-10-31
+
+### Dependencies
+
+- Bump `paft` to `v0.7.1`.
+
+### Note
+
+Yahoo Finance appears to have removed or relocated the ESG data endpoint. As a result, `ticker.sustainability()` currently panics during normal usage and live testing. This issue is under investigation.
+
+## [0.7.1] - 2025-10-30
+
+### Fixed
+
+- Format fundamentals timeseries statement row period from epoch to YYYY-MM-DD.
+- Correct `calendarEvents` mapping and extraction for `exDividendDate` and `dividendDate`.
+- Correct gross profit and operating income in income statement.
+
+## [0.7.0] - 2025-10-28
+
+### Added
+
+- Per-update volume deltas in real-time streaming: `QuoteUpdate.volume` now reflects the delta
+  since the previous update for a symbol. First tick per symbol and after a detected reset/rollover
+  yields `None`. Applies to both WebSocket and HTTP polling streams.
+- Expose intraday cumulative volume on snapshots: populate `Quote.day_volume` from v7 quotes and
+  surface it on convenience types (`Ticker::quote()` and `Ticker::info()` as `Info.volume`).
+- SearchBuilder accessors: `lang_ref()` and `region_ref()` to inspect configured parameters.
+- Populate convenience `Info` with analytics and ESG when available: `price_target`,
+  `recommendation_summary`, `esg_scores`.
+
+### Breaking Change
+
+- Upgrade to `paft` v0.7.0 adds a new field to `paft::market::quote::QuoteUpdate`:
+  `volume: Option<u64>`. If you construct or exhaustively destructure `QuoteUpdate`, update your
+  code to include the new field or use `..`. Stream APIs and typical consumers that only read
+  updates are unaffected.
+
+### Changed
+
+- Stream volume semantics: WebSocket and polling streams compute per-update volume deltas. The
+  low-level decoder helper remains stateless and always returns `volume = None`.
+- Polling stream `diff_only` now emits when either price or volume changes.
+
+### Documentation
+
+- README: added a "Volume semantics" section for streaming; clarified delta behavior and how to
+  obtain cumulative volume.
+- Examples: updated streaming and convenience examples to display volume; SearchBuilder example now
+  demonstrates `lang_ref()`/`region_ref()`.
+
+### Dependencies
+
+- Bump `paft` to `v0.7.0`.
+
+## [0.6.1] - 2025-10-27
+
+### Fixed
+
+- Fixed critical timestamp interpretation bug in WebSocket stream processing: use `DateTime::from_timestamp_millis()` instead of `i64_to_datetime()` to correctly interpret millisecond timestamps, preventing incorrect date values in quote updates
+
+#### Notes
+
+- **WebSocket Stream Timestamps:** Users may occasionally observe `QuoteUpdate` messages arriving via the WebSocket stream with timestamps that are older than previously received messages ("time traveling ticks"), sometimes by significant amounts (minutes or hours). This behavior appears to originate from the **Yahoo Finance data feed itself** and is not a bug introduced by `yfinance-rs`. To provide the most direct representation of the source data, `yfinance-rs` **does not automatically filter** these out-of-order messages. Applications requiring strictly chronological quote updates should implement their own filtering logic based on the timestamp (`ts`) field of the received `QuoteUpdate`.
+
+## [0.6.0] - 2025-10-21
+
+### Breaking Change
+
+- `DownloadBuilder::run()` now returns `paft::market::responses::download::DownloadResponse` with an `entries: Vec<DownloadEntry>` instead of the previous `DownloadResult` maps. Access candles via `entry.history.candles` and the symbol via `entry.instrument.symbol_str()`.
+
+### Changed
+
+- Re-export `DownloadEntry` and `DownloadResponse` at the crate root for convenient imports.
+- Examples and tests updated to iterate over `entries` rather than `series`.
+
+### Performance
+
+- Introduced an instrument cache in `YfClient` and populate it opportunistically from v7 quote responses to reduce symbol resolution overhead during multi-symbol downloads.
+
+### Documentation
+
+- Updated README examples to reflect the new `DownloadResponse.entries` usage.
+
+### Dependencies
+
+- Bump `paft` to `v0.6.0`.
+
+## [0.5.2] - 2025-10-20
+
+### Added
+
+- Optional `tracing` feature: emits spans and key events across network I/O and major logical boundaries. Instrumented `send_with_retry`, profile fallback, quote summary fetch (including invalid crumb retry), history `fetch_full`, and `Ticker` public APIs (`info`, `quote`, `history`, etc.). Disabled by default; zero overhead when not enabled.
+- Optional `tracing-subscriber` feature (dev/testing): convenience initializer `init_tracing_for_tests()` to set up a basic subscriber in examples/tests. The library itself does not configure a subscriber.
+
+### Dependencies
+
+- Bump `paft` to `v0.5.2`.
+
+### Docs
+
+- Readme now includes a "Tracing" section.
+
+## [0.5.1] - 2025-10-17
+
+### Changed
+
+- Updated to paft v0.5.1
+
+## [0.5.0] - 2025-10-16
+
+### Breaking
+
+- Adopted `paft` 0.5.0 identity and money types across search, streaming, and ticker info. `Quote.symbol`, `SearchResult.symbol`, `OptionContract.contract_symbol`, and `QuoteUpdate.symbol` now use `paft::domain::Symbol`; values are uppercased and validated during construction, and invalid search results are dropped.
+- `Ticker::Info` now re-exports `paft::aggregates::Info`. The previous struct with raw strings and floats has been removed, and fields such as `sector`, `industry`, analyst targets, recommendation metrics, and ESG scores are no longer populated on this convenience type. Monetary and exchange data now use `Money`, `Currency`, `Exchange`, and `MarketState`.
+- Real-time streaming emits `paft::market::quote::QuoteUpdate`. `last_price` is renamed to `price` and now carries `Money` (with embedded currency metadata), the standalone `currency` string is gone, and `ts` is now a `DateTime<Utc>`. Update stream consumers accordingly.
+- Search now returns `paft::market::responses::search::SearchResponse` with a `results` list. Each item exposes `Symbol`, `AssetKind`, and `Exchange` enums. Replace usages of `resp.quotes` and `quote.longname/shortname` with `resp.results` and `result.name`.
+
+### Changed
+
+- Bumped `paft` to 0.5.0 via the workspace checkout and aligned with the new symbol validation.
+- Updated dependencies and fixtures: `reqwest 0.12.24`, `tokio 1.48`.
+
+### Documentation
+
+- Added troubleshooting guidance for consent-related errors in `README.md` (thanks to [@hrishim](https://github.com/hrishim) for the contribution!)
+- Expanded `CONTRIBUTING.md` with `just` helpers and clarified repository setup.
+
+### Internal
+
+- Added `.github/FUNDING.yml` to advertise GitHub Sponsors support.
+- Removed stray `.DS_Store` files and regenerated fixtures for the new models.
+
+### Migration notes
+
+- Symbols are now uppercase-validated `paft::domain::Symbol`. Use `.as_str()` for string comparisons or construct values with `Symbol::new("AAPL")` (handle the `Result` when user input is dynamic).
+- Stream updates now expose `update.price` (`Money`) and `update.ts: DateTime<Utc>`. Replace direct `last_price`/`ts` usage with the new typed fields and derive primitive values as needed.
+- Search responses provide `resp.results` instead of `resp.quotes`. Access display data via `result.name`, `result.kind`, and `result.exchange`.
+- The convenience info snapshot no longer embeds fundamentals, analyst, or ESG data. Fetch those via `profile::load_profile`, `analysis::AnalysisBuilder`, and `esg::EsgBuilder` if you still need them.
+
+---
+
+## [0.4.0] - 2025-10-12
+
+### Added
+
+- Enabled `paft` facade `aggregates` feature.
+  - `Ticker::fast_info()` now returns `paft_aggregates::FastInfo` (typed enums and `Money`), offering a richer, consistent snapshot model.
+- Options models expanded (re-exported from `paft-market`):
+  - `OptionContract` gains `expiration_date` (NaiveDate), `expiration_at` (Option<DateTime\<Utc>>), `last_trade_at` (Option<DateTime\<Utc>>), and `greeks` (Option\<OptionGreeks>).
+- DataFrame support for options types is available when enabling this crate’s `dataframe` feature (forwards to `paft/dataframe`).
+
+### Changed
+
+- History response alignment with `paft` 0.4.0:
+  - `Candle` now carries `close_unadj: Option<Money>` (original unadjusted close, when available).
+  - `HistoryResponse` no longer includes a top-level `unadjusted_close` vector.
+- Examples and tests updated to use Money-typed values and typed enums (Exchange, MarketState, Currency).
+
+### Breaking
+
+- Fast Info return type changed:
+  - Old: struct with `last_price: f64`, `previous_close: Option<f64>`, string-y `currency`/`exchange`/`market_state`.
+  - New: `paft_aggregates::FastInfo` with `last: Option<Money>`, `previous_close: Option<Money>`, `currency: Option<paft_money::Currency>`, `exchange: Option<paft_domain::Exchange>`, `market_state: Option<paft_domain::MarketState>`, plus `name: Option<String>`.
+- Options contract fields changed:
+  - Old: `OptionContract { ..., expiration: DateTime<Utc>, ... }`
+  - New: `OptionContract { ..., expiration_date: NaiveDate, expiration_at: Option<DateTime<Utc>>, last_trade_at: Option<DateTime<Utc>>, greeks: Option<OptionGreeks>, ... }`
+- History unadjusted close location changed:
+  - Old: `HistoryResponse { ..., unadjusted_close: Option<Vec<Money>> }`
+  - New: `Candle { ..., close_unadj: Option<Money> }` (per-candle).
+
+### Migration notes
+
+- Fast Info
+  - Price as f64: replace `fi.last_price` with `fi.last.as_ref().map(money_to_f64).or_else(|| fi.previous_close.as_ref().map(money_to_f64))`.
+  - Currency string: replace `fi.currency` (String) with `fi.currency.map(|c| c.to_string())`.
+  - Exchange/MarketState strings: `.map(|e| e.to_string())`.
+- Options
+  - Replace usages of `contract.expiration` with `contract.expiration_at.unwrap_or_else(|| ...)`, or use `contract.expiration_date` for calendar-only logic.
+  - New optional fields `last_trade_at` and `greeks` are available (greeks currently not populated from Yahoo v7).
+- History
+  - Replace `resp.unadjusted_close[i]` with `resp.candles[i].close_unadj.as_ref()`.
+
+### Internal
+
+- Tests updated for `httpmock` 0.8 API changes.
+- Lints and examples adjusted for Money/typed enums.
+
+## [0.3.2] - 2025-10-03
+
+### Changed
+
+- Bump `paft` to 0.3.2 (docs-only upstream release; no functional impact).
+
+## [0.3.1] - 2025-10-02
+
+### Changed
+
+- Internal migration to `paft` 0.3.0 without changing the public API surface.
+  - Switched internal imports to `paft::domain` (domain types) and `paft::money` (money/currency).
+  - Updated internal `Money` construction to the new `Result`-returning API and replaced scalar ops with `try_mul` where appropriate.
+- Examples and docs now import DataFrame traits from `paft::prelude::{ToDataFrame, ToDataFrameVec}`.
+- Conversion helpers in `core::conversions` now document potential panics if a non-ISO currency lacks registered metadata (behavior aligned with `paft-money`).
+- Profile ISIN fields now validate ISIN format using `paft::domain::Isin` - invalid ISINs are filtered out and stored as `None`.
+- Updated tokio-tungstenite to version 0.28
+
+## [0.3.0] - 2025-09-20
+
+### Changed
+
+- Migrated to `paft` 0.2.0 with explicit module paths; removed all `paft::prelude` imports across the codebase, tests, and examples.
+- Updated enum/string conversions to use `FromStr/TryFrom` parsing from `paft` 0.2.0 (e.g., `MarketState`, `Exchange`, `Period`, insider/transaction/recommendation types).
+- Adjusted `Money` operations to use `try_*` methods and made conversions more robust against non-finite values.
+- Consolidated public re-exports under `core::models` (e.g., `Interval`, `Range`, `Quote`, `Action`, `Candle`, `HistoryMeta`, `HistoryResponse`) to provide stable, explicit paths.
+- Simplified the Polars example behind the `dataframe` feature to avoid prelude usage and to compile cleanly with the new APIs.
+
+### Fixed
+
+- Updated examples and tests to import `Interval`/`Range` from `yfinance_rs::core` explicitly and to avoid wildcard matches in pattern tests.
+
+### Notes
+
+- This release removes reliance on `paft` preludes and may require users to update imports to explicit module paths if depending on re-exported paft items directly.
+
+## [0.2.1] - 2025-09-18
+
+### Added
+
+- Profile-based reporting currency inference with per-symbol caching. The client now inspects the profile country on first use to determine an appropriate currency and reuses that decision across fundamentals and analysis calls.
+- ESG involvement exposure: `Ticker::sustainability()` now returns involvement flags (e.g., tobacco, thermal_coal) alongside component scores via `EsgSummary`.
+
+### Changed
+
+- **Breaking change:** `Ticker` convenience methods for fundamentals and analysis (and their corresponding builders) now accept an extra `Option<Currency>` argument. Pass `None` to use the inferred reporting currency, or `Some(currency)` to override the heuristic explicitly.
+- **Breaking change:** `Ticker::sustainability()` and `esg::EsgBuilder::fetch()` now return `EsgSummary` instead of `EsgScores`. Access component values via `summary.scores` and involvement via `summary.involvement`.
+
+## [0.2.0] - 2025-09-16
+
+### Added
+
+- New optional `dataframe` feature: all `paft` data models now support `.to_dataframe()` when the feature is enabled, returning Polars `DataFrame`s. Added example `14_polars_dataframes.rs` and README section.
+- Custom HTTP client support via `YfClient::builder().custom_client(...)` for full control over `reqwest` configuration.
+- Proxy configuration helpers on the client builder: `.proxy()`, `.https_proxy()`, `.try_proxy()`, `.try_https_proxy()`. Added example `13_custom_client_and_proxy.rs`.
+- Explicit `User-Agent` is set on all HTTP/WebSocket requests by default, with `.user_agent(...)` to customize it.
+- Improved numeric precision in historical adjustments and conversions using `rust_decimal`.
+
+### Changed
+
+- **Breaking change:** All public data models (such as `Quote`, `HistoryBar`, `EarningsTrendRow`, etc.) now use types from the [`paft`](https://crates.io/crates/paft) crate instead of custom-defined structs. This unifies data structures with other financial Rust libraries and improves interoperability, but may require code changes for downstream users.
+- Monetary value handling now uses `paft::Money` with currency awareness across APIs and helpers.
+- Consolidated and simplified fundamentals timeseries fetching via a generic helper for consistency.
+- Error handling refined: `YfError` variants and messages standardized for 404/429/5xx and unexpected statuses.
+- Dependencies updated and internal structure adjusted to support the new features.
+
+### Fixed
+
+- Minor clippy findings and documentation typos.
+
+### Known Issues
+
+- Currency inference relies on company profile metadata. If Yahoo omits or mislabels the headquarters country, the inferred currency can still be incorrect—use the new override parameter to force a specific currency in that case.
+
+## [0.1.3] - 2025-08-31
+
+### Added
+
+- Re-exported `CacheMode` and `RetryConfig` from the `core` module.
+
+### Changed
+
+- `Ticker::new` now takes `&YfClient` instead of taking ownership.
+- `SearchBuilder` now takes `&YfClient` instead of taking ownership.
+
+## [0.1.2] - 2025-08-30
+
+### Added
+
+- New examples: `10_convenience_methods.rs`, `11_builder_configuration.rs`, `12_advanced_client.rs`.
+- Development tooling: `just` recipes `lint`, `lint-fix`, and `lint-strict`.
+- Re-exported `YfClientBuilder` at the crate root (`use yfinance_rs::YfClientBuilder`).
+
+### Changed
+
+- Centralized raw wire types (e.g., `RawNum`) into `src/core/wire.rs`.
+- Gated debug file dumps behind the `debug-dumps` feature flag.
+
+### Fixed
+
+- Analyst recommendations now read from `financialData` instead of the incorrect `recommendationMean` field.
+- Fixed unnecessary mutable borrow in `StreamBuilder` `run_websocket_stream`
+
+## [0.1.1] - 2025-08-28
+
+### Added
+
+- `ticker.earnings_trend()` for analyst earnings and revenue estimates.
+- `ticker.shares()` and `ticker.quarterly_shares()` for historical shares outstanding.
+- `ticker.capital_gains()` and inclusion of capital gains in `ticker.actions()`.
+- Documentation: added doc comments for `EarningsTrendRow`, `ShareCount`, and `Action::CapitalGain`.
+
+## [0.1.0] - 2025-08-27
+
+### Added
+
+- Initial release of `yfinance-rs`.
+- Core functionality: `info`, `history`, `quote`, `fast_info`.
+- Advanced data: `options`, `option_chain`, `news`, `income_stmt`, `balance_sheet`, `cashflow`.
+- Analysis tools: `recommendations`, `sustainability`, `major_holders`, `institutional_holders`.
+- Utilities: `DownloadBuilder`, `StreamBuilder`, `SearchBuilder`.

+
+## Overview
+
+An ergonomic, async-first Rust client for the unofficial Yahoo Finance API. It provides a simple and efficient way to fetch financial data, with a convenient, yfinance-like API, leveraging Rust's type system and async runtime for performance and safety.
+
+## Features
+
+### Core Data
+
+* **Historical Data**: Fetch daily, weekly, or monthly OHLCV data with automatic split/dividend adjustments.
+* **Real-time Quotes**: Get live quote updates with detailed market information.
+* **Fast Quotes**: Optimized quote fetching with essential data only (`fast_info`).
+* **Multi-Symbol Downloads**: Concurrently download historical data for many symbols at once.
+* **Batch Quotes**: Fetch quotes for multiple symbols efficiently.
+
+### Corporate Actions & Dividends
+
+* **Dividend History**: Fetch complete dividend payment history with amounts and dates.
+* **Stock Splits**: Get stock split history with split ratios.
+* **Capital Gains**: Retrieve capital gains distributions (especially for mutual funds).
+* **All Corporate Actions**: Comprehensive access to dividends, splits, and capital gains in one call.
+
+### Financial Statements & Fundamentals
+
+* **Income Statements**: Access annual and quarterly income statements.
+* **Balance Sheets**: Get annual and quarterly balance sheet data.
+* **Cash Flow Statements**: Fetch annual and quarterly cash flow data.
+* **Earnings Data**: Historical earnings, revenue estimates, and EPS data.
+* **Shares Outstanding**: Historical data on shares outstanding (annual and quarterly).
+* **Corporate Calendar**: Earnings dates, ex-dividend dates, and dividend payment dates.
+
+### Options & Derivatives
+
+* **Options Chains**: Fetch expiration dates and full option chains (calls and puts).
+* **Option Contracts**: Detailed option contract information.
+
+### Analysis & Research
+
+* **Analyst Ratings**: Get price targets, recommendations, and upgrade/downgrade history.
+* **Earnings Trends**: Detailed earnings and revenue estimates from analysts.
+* **Recommendations Summary**: Summary of current analyst recommendations.
+* **Upgrades/Downgrades**: History of analyst rating changes.
+
+### Ownership & Holders
+
+* **Major Holders**: Get major, institutional, and mutual fund holder data.
+* **Institutional Holders**: Top institutional shareholders and their holdings.
+* **Mutual Fund Holders**: Mutual fund ownership breakdown.
+* **Insider Transactions**: Recent insider buying and selling activity.
+* **Insider Roster**: Company insiders and their current holdings.
+* **Net Share Activity**: Summary of insider purchase/sale activity.
+
+### ESG & Sustainability
+
+* **ESG Scores**: Fetch detailed Environmental, Social, and Governance ratings.
+* **ESG Involvement**: Specific ESG involvement and controversy data.
+
+### News & Information
+
+* **Company News**: Retrieve the latest articles and press releases for a ticker.
+* **Company Profiles**: Detailed information about companies, ETFs, and funds.
+* **Search**: Find tickers by name or keyword.
+
+### Real-time Streaming (WebSocket/Polling)
+
+* **WebSocket Streaming**: Get live quote updates using WebSockets (preferred method).
+* **HTTP Polling**: Fallback polling method for real-time data.
+* **Configurable Streaming**: Customize update frequency and change-only filtering.
+* **Per-update volume deltas**: `QuoteUpdate.volume` reflects the delta since the previous update for that symbol. The first observed tick (and after a reset/rollover) has `volume = None`.
+
+### Advanced Features
+
+* **Data Repair**: Automatic detection and repair of price outliers.
+* **Data Rounding**: Control price precision and rounding.
+* **Missing Data Handling**: Configurable handling of NA/missing values.
+* **Back Adjustment**: Alternative price adjustment methods.
+* **Historical Metadata**: Timezone and other metadata for historical data.
+* **ISIN Lookup**: Get International Securities Identification Numbers.
+* **Polars DataFrames**: Convert results to Polars DataFrames via `.to_dataframe()` (enable the `dataframe` feature).
+
+### Developer Experience
+
+* **Async API**: Built on `tokio` and `reqwest` for non-blocking I/O.
+* **High-Level `Ticker` Interface**: A convenient, yfinance-like struct for accessing all data for a single symbol.
+* **Builder Pattern**: Fluent builders for constructing complex queries.
+* **Configurable Retries**: Automatic retries with exponential backoff for transient network errors.
+* **Caching**: Configurable caching behavior for API responses.
+* **Custom Timeouts**: Configurable request timeouts and connection settings.
+
+## Quick Start
+
+To get started, add `yfinance-rs` to your `Cargo.toml`:
+
+```toml
+[dependencies]
+yfinance-rs = "0.7.2"
+tokio = { version = "1", features = ["full"] }
+```
+
+To enable DataFrame conversions backed by Polars, turn on the optional `dataframe` feature and (if you use Polars types in your code) add `polars`:
+
+```toml
+[dependencies]
+yfinance-rs = { version = "0.7.2", features = ["dataframe"] }
+polars = "0.51"
+```
+
+Then, create a `YfClient` and use a `Ticker` to fetch data.
+
+```rust
+use yfinance_rs::{Interval, Range, Ticker, YfClient};
+use yfinance_rs::core::conversions::money_to_f64;
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    let client = YfClient::default();
+    let ticker = Ticker::new(&client, "AAPL");
+
+    // Get the latest quote
+    let quote = ticker.quote().await?;
+    println!(
+        "Latest price for AAPL: ${:.2}",
+        quote.price.as_ref().map(money_to_f64).unwrap_or(0.0)
+    );
+
+    // Get historical data for the last 6 months
+    let history = ticker.history(Some(Range::M6), Some(Interval::D1), false).await?;
+    if let Some(last_bar) = history.last() {
+        println!(
+            "Last closing price: ${:.2} on {}",
+            money_to_f64(&last_bar.close),
+            last_bar.ts
+        );
+    }
+
+    // Get analyst recommendations
+    let recs = ticker.recommendations().await?;
+    if let Some(latest_rec) = recs.first() {
+        println!("Latest recommendation period: {}", latest_rec.period);
+    }
+
+    // Dividends in the last year
+    let dividends = ticker.dividends(Some(Range::Y1)).await?;
+    println!("Found {} dividend payments in the last year", dividends.len());
+
+    // Earnings trend
+    let trends = ticker.earnings_trend(None).await?;
+    if let Some(latest) = trends.first() {
+        println!(
+            "Latest earnings estimate: ${:.2}",
+            latest
+                .earnings_estimate
+                .avg
+                .as_ref()
+                .map(money_to_f64)
+                .unwrap_or(0.0)
+        );
+    }
+
+    Ok(())
+}
+```
+
+### Troubleshooting
+
+**Possible network or consent issues**
+
+Some users [have reported](https://github.com/gramistella/yfinance-rs/issues/1) encountering errors on first use, such as:
+
+- `Rate limited at ...`  
+- `HTTP error: error sending request for url (https://fc.yahoo.com/consent)`
+
+These are typically **environmental** (network or regional) issues with Yahoo’s public API.  
+In some regions, Yahoo may require a one-time consent or session initialization.
+
+**Workaround:**  
+Open [`https://fc.yahoo.com/consent`](https://fc.yahoo.com/consent) in a web browser **from the same network** before running your code again.  
+This usually resolves the issue for that IP/network.
+
+### Tracing (optional)
+
+This crate can emit structured tracing spans and key events when the optional `tracing` feature is enabled. When disabled (default), all instrumentation is compiled out with zero overhead. The library does not configure a subscriber; set one up in your application.
+
+Spans are added at: `Ticker` public APIs (`info`, `quote`, `history`, etc.), HTTP `send_with_retry`, profile fallback, quote summary fetch (including invalid-crumb retry), and full history fetch. Key events include retry/backoff and fallback notifications.
+
+## Advanced Examples
+
+### Polars DataFrames (to_dataframe)
+
+Enable the `dataframe` feature to convert paft models into a Polars `DataFrame` with `.to_dataframe()`.
+
+```rust
+use yfinance_rs::{Interval, Range, Ticker, YfClient};
+use paft::prelude::{ToDataFrame, ToDataFrameVec};
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    let client = YfClient::default();
+    let ticker = Ticker::new(&client, "AAPL");
+
+    // Quote → DataFrame
+    let quote_df = ticker.quote().await?.to_dataframe()?;
+    println!("Quote as DataFrame:\n{}", quote_df);
+
+    // History (Vec<Candle>) → DataFrame
+    let hist_df = ticker
+        .history(Some(Range::M1), Some(Interval::D1), false)
+        .await?
+        .to_dataframe()?;
+    println!("History rows: {}", hist_df.height());
+
+    Ok(())
+}
+```
+
+Works for quotes, historical candles, fundamentals, analyst data, holders, options, and more. All `paft` structs returned by this crate implement `.to_dataframe()` when the `dataframe` feature is enabled. See the full example: `examples/14_polars_dataframes.rs`.
+
+### Multi-Symbol Data Download
+
+```rust
+use yfinance_rs::{DownloadBuilder, Interval, Range, YfClient};
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    let client = YfClient::default();
+    let symbols = vec!["AAPL", "GOOGL", "MSFT", "TSLA"];
+
+    let results = DownloadBuilder::new(&client)
+        .symbols(symbols)
+        .range(Range::M6)
+        .interval(Interval::D1)
+        .auto_adjust(true)
+        .actions(true)
+        .repair(true)
+        .rounding(true)
+        .run()
+        .await?;
+
+    for entry in &results.entries {
+        println!("{}: {} data points", entry.instrument.symbol(), entry.history.candles.len());
+    }
+    Ok(())
+}
+```
+
+### Real-time Streaming
+
+```rust
+use yfinance_rs::{StreamBuilder, StreamMethod, YfClient};
+use std::time::Duration;
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    let client = YfClient::default();
+    let (handle, mut receiver) = StreamBuilder::new(&client)
+        .symbols(vec!["AAPL", "GOOGL"]) 
+        .method(StreamMethod::WebsocketWithFallback)
+        .interval(Duration::from_secs(1))
+        .diff_only(true)
+        .start()?;
+
+    while let Some(update) = receiver.recv().await {
+        let vol = update.volume.map(|v| format!(" (vol Δ: {v})")).unwrap_or_default();
+        println!("{}: ${:.2}{}",
+            update.symbol,
+            update.price.as_ref().map(yfinance_rs::core::conversions::money_to_f64).unwrap_or(0.0),
+            vol);
+    }
+#### Volume semantics
+
+Yahoo’s websocket stream provides cumulative intraday volume (`day_volume`). This crate converts it to per-update deltas on the consumer-facing `QuoteUpdate`:
+
+- First tick per symbol and after a detected reset (current < last): `volume = None`.
+- Otherwise: `volume = Some(current_day_volume - last_day_volume)`.
+- The polling stream applies the same logic using the v7 `regularMarketVolume` field.
+- The low-level decoder helper `stream::decode_and_map_message` is stateless and always returns `volume = None`.
+
+If you need cumulative volume, sum the emitted per-update `volume` values, or use `Quote.day_volume` from the quote endpoints.
+
+    Ok(())
+}
+```
+
+### Financial Statements
+
+```rust
+use yfinance_rs::{Ticker, YfClient};
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    let client = YfClient::default();
+    let ticker = Ticker::new(&client, "AAPL");
+
+    let income_stmt = ticker.quarterly_income_stmt(None).await?;
+    let balance_sheet = ticker.quarterly_balance_sheet(None).await?;
+    let cashflow = ticker.quarterly_cashflow(None).await?;
+
+    println!("Found {} quarterly income statements.", income_stmt.len());
+    println!("Found {} quarterly balance sheet statements.", balance_sheet.len());
+    println!("Found {} quarterly cashflow statements.", cashflow.len());
+
+    let shares = ticker.quarterly_shares().await?;
+    if let Some(latest) = shares.first() {
+        println!("Latest shares outstanding: {}", latest.shares); 
+    }
+    Ok(())
+}
+```
+
+> 💡 Need to force a specific reporting currency? Pass `Some(paft::money::Currency::USD)` (or another currency) instead of `None` when calling the fundamentals/analysis helpers.
+
+### Options Trading
+
+```rust
+use yfinance_rs::{Ticker, YfClient};
+use yfinance_rs::core::conversions::money_to_f64;
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    let client = YfClient::default();
+    let ticker = Ticker::new(&client, "AAPL");
+
+    let expirations = ticker.options().await?;
+
+    if let Some(nearest) = expirations.first() {
+        let chain = ticker.option_chain(Some(*nearest)).await?;
+    
+        println!("Calls: {}", chain.calls.len());
+        println!("Puts: {}", chain.puts.len());
+    
+        let fi = ticker.fast_info().await?;
+        let current_price = fi
+            .last
+            .as_ref()
+            .map(money_to_f64)
+            .or_else(|| fi.previous_close.as_ref().map(money_to_f64))
+            .unwrap_or(0.0);
+        for call in &chain.calls {
+            if (money_to_f64(&call.strike) - current_price).abs() < 5.0 {
+                println!(
+                    "ATM Call: Strike ${:.2}, Bid ${:.2}, Ask ${:.2}", 
+                    money_to_f64(&call.strike),
+                    call.bid.as_ref().map(money_to_f64).unwrap_or(0.0),
+                    call.ask.as_ref().map(money_to_f64).unwrap_or(0.0)
+                );
+            }
+        }
+    }
+    Ok(())
+}
+```

+
+#### Custom Reqwest Client
+
+For full control over HTTP configuration, you can provide your own reqwest client:
+
+```rust
+use yfinance_rs::{YfClient, Ticker};
+use yfinance_rs::core::conversions::money_to_f64;
+use reqwest::Client;
+use std::time::Duration;
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    let custom_client = Client::builder()
+        .user_agent("yfinance-rs-playground") // Make sure to set a proper user agent
+        .timeout(Duration::from_secs(30))
+        .connect_timeout(Duration::from_secs(10))
+        .pool_idle_timeout(Duration::from_secs(90))
+        .pool_max_idle_per_host(10)
+        .tcp_keepalive(Some(Duration::from_secs(60)))
+        .build()?;
+
+    let client = YfClient::builder()
+        .custom_client(custom_client)
+        .cache_ttl(Duration::from_secs(300))
+        .build()?;
+
+    let ticker = Ticker::new(&client, "AAPL");
+    let quote = ticker.quote().await?;
+    println!(
+        "Latest price for AAPL: ${:.2}",
+        quote.price.as_ref().map(money_to_f64).unwrap_or(0.0)
+    );
+
+    Ok(())
+}
+```
+
+#### Proxy Configuration
+
+You can configure HTTP/HTTPS proxies through the builder:
+
+```rust
+use yfinance_rs::{YfClient, YfClientBuilder, Ticker};
+use yfinance_rs::core::conversions::money_to_f64;
+use std::time::Duration;
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    let client = YfClient::builder()
+        .try_proxy("http://proxy.example.com:8080")?
+        .timeout(Duration::from_secs(30))
+        .build()?;
+
+    let client_https = YfClient::builder()
+        .try_https_proxy("https://proxy.example.com:8443")?
+        .timeout(Duration::from_secs(30))
+        .build()?;
+
+    let client_simple = YfClient::builder()
+        .proxy("http://proxy.example.com:8080")
+        .timeout(Duration::from_secs(30))
+        .build()?;
+
+    let ticker = Ticker::new(&client, "AAPL");
+    let quote = ticker.quote().await?;
+    println!(
+        "Latest price for AAPL via proxy: ${:.2}",
+        quote.price.as_ref().map(money_to_f64).unwrap_or(0.0)
+    );
+
+    Ok(())
+}
