tradestation-api

Complete, typed TradeStation REST API v3 wrapper for Rust.

Provides async access to all TradeStation v3 endpoints with automatic OAuth2 token management, typed request/response models, and HTTP chunked-transfer streaming.

Installation

cargo add tradestation-api

Quick Start

use tradestation_rs::{Client, Credentials, Scope};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let creds = Credentials::new("YOUR_CLIENT_ID", "YOUR_CLIENT_SECRET");

    // 1. Direct user to authorization URL
    let url = creds.authorization_url(&Scope::defaults());
    println!("Visit: {url}");

    // 2. Exchange the callback code for tokens
    let mut client = Client::new(creds);
    client.authenticate("AUTH_CODE_FROM_CALLBACK").await?;

    // 3. Fetch data
    let quotes = client.get_quotes(&["AAPL", "MSFT"]).await?;
    for q in &quotes {
        println!("{}: last={}", q.symbol, q.last);
    }

    Ok(())
}

Features

• OAuth2 Authorization Code flow with automatic token refresh
• Market Data: Historical bars (OHLCV), quotes, symbol info, crypto pairs, options data
• Brokerage: Accounts, balances, BOD balances, positions, orders, historical orders, wallets
• Execution: Place, replace, cancel orders; OCO/bracket groups; order preview; activation triggers; routes
• Streaming: HTTP chunked-transfer for live quotes, bars, market depth, option chains, orders, positions
• Simulation: Built-in support for TradeStation's sim API via Client::with_sim()
• Typed models: All API responses are strongly typed with serde deserialization
• Convenience parsers: Bar::ohlcv() and Bar::timestamp() for numeric/datetime conversion

Endpoint Coverage

Total: 38 endpoints

Relationship to Other Crates

This is a new, independent crate -- not a fork of any existing TradeStation library. It was built from scratch against the TradeStation v3 OpenAPI spec with a focus on:

• Complete endpoint coverage (all 38 v3 endpoints)
• Idiomatic async Rust with tokio and futures
• Typed streaming via HTTP chunked transfer (not WebSocket)
• Zero external runtime dependencies beyond tokio + reqwest

Examples

See the examples/ directory:

• quickstart.rs -- OAuth2 flow and fetching quotes
• stream_quotes.rs -- Real-time quote streaming
• place_order.rs -- Order placement (use sim API!)
