Yahoo Finance sources

You receive an archive containing the C# source code of the S#.Yahoo adapter, which downloads historical Yahoo Finance data over HTTP and converts it to the API message model. The source lets you inspect service requests, JSON response parsing, and the creation of instrument, candle, and corporate-action messages. The connector is also available as a separate product: Yahoo Finance.

The adapter is based on HistoricalMessageAdapter and calls the Yahoo Finance /v8/finance/chart/{symbol} route. The project uses no native DLL and does not require an installed trading terminal.

• Instrument metadata: the requested ticker is resolved to its symbol, exchange, currency, price precision, instrument type, and first-trade date.
• Historical candles: daily, weekly, and monthly OHLCV candles are supported for a specified date range, with an optional result-count limit.
• Corporate actions: dividends and stock splits are converted to Level1 changes.
• Closing prices: the response model parses AdjClose, but the current adapter emits regular Close values and does not produce a separate adjusted series.
• Network layer: requests use HttpClient, and Yahoo responses are converted to internal models before StockSharp messages are emitted.

This is a historical adapter without streaming quotes or trading operations. Available tickers, dates, intervals, and corporate actions depend on the data returned by Yahoo Finance.
