Market Data

tastytrade does not provide access to market data through their API, so the we use market data from Polygon at no additional charge to you for stocks and crypto only.

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.

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.
