# tastytrade ## Contact Information Email: Phone: [+1 (888) 247-1963](tel:18882471963) ## Supported Asset Classes * Stocks * Options * Futures * Crypto ## Market Data tastytrade does not provide access to market data through their API, so the we use market data from [Polygon](https://polygon.io/) at no additional charge to you for stocks and crypto only. {% hint style="warning" %} The futures asset class within tastytrade does not support market data, so you cannot fetch quotes for futures symbols or view the P\&L for futures positions. {% endhint %} ## Fractional Quantities tastytrade supports fractional quantities for both **crypto** and **stocks**, but there are important limitations, especially when it comes to **automated trading** of stocks. ### **Stocks** While tastytrade technically allows holding fractional stock shares, **fractional quantities are not fully supported for automated trading**. This functionality is primarily intended to handle small fractional amounts received from **dividends or account adjustments**, not for executing full or partial trades. For example: * If you own **4.99 shares** of a stock: * You **cannot** submit a single order to sell all 4.99 shares. * You must **first sell the 0.99 fractional shares**, then submit a separate order to sell the remaining 4 whole shares. Because of this limitation, we **strongly recommend disabling fractional quantities** when using tastytrade with TradersPost. ### **Crypto** Fractional trading is **fully supported** for cryptocurrencies on tastytrade. You can buy and sell fractional crypto positions in a single order without any special handling. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
