tastytrade

tastytrade is a Rust client library for the Tastytrade API, providing programmatic access to trading functionality, market data, and account information.

Features

• Authentication with Tastytrade accounts
• Real-time market data streaming via DxFeed
• Account and positions information
• Order management (placing, modifying, canceling)
• Real-time account streaming for balance updates and order status changes

Usage

use tastytrade::TastyTrade;
use tastytrade::utils::config::Config;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Login to Tastytrade

    let config = Config::from_env();
    let tasty = TastyTrade::login(&config).await?;

    // Get account information
    let accounts = tasty.accounts().await?;
    for account in accounts {
        println!("Account: {}", account.number().0);

        // Get positions
        let positions = account.positions().await?;
        println!("Positions: {}", positions.len());
    }

    Ok(())
}

Real-time Data

The library supports real-time data streaming for both market data and account updates using DXLink:

// Create a quote streamer
use tastytrade::{Symbol, TastyTrade};
use tastytrade::utils::config::Config;
use dxfeed::{Event, EventData};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let config = Config::from_env();
    let tasty = TastyTrade::login(&config)
           .await
           .unwrap();
    let mut quote_streamer = tasty.create_quote_streamer().await?;
    let mut quote_sub = quote_streamer.create_sub(dxfeed::DXF_ET_QUOTE | dxfeed::DXF_ET_GREEKS);

    // Add symbols to subscribe to
    quote_sub.add_symbols(&[Symbol("AAPL".to_string())]);

    // Listen for events
    if let Ok(Event { sym, data }) = quote_sub.get_event().await {
        match data {
            EventData::Quote(quote) => {
                println!("Quote for {}: {}/{}", sym, quote.bid_price, quote.ask_price);
            }
            _ => {}
        }
    }
    Ok(())
}
