Installation

npm install tradestation-api-ts

Usage

Basic Setup

import { TradeStationClient } from 'tradestation-api-ts';

// Initialize with environment variables
// Automatically reads CLIENT_ID, CLIENT_SECRET (optional), REFRESH_TOKEN, and ENVIRONMENT from .env
const client = new TradeStationClient();

// Or with explicit configuration
const client = new TradeStationClient({
    refresh_token: 'your_refresh_token',
    environment: 'Simulation'  // or 'Live'
});

Market Data

// Get quote snapshots
const quotes = await client.marketData.getQuoteSnapshots(['MSFT', 'AAPL']);

// Stream real-time quotes
const stream = await client.marketData.streamQuotes(['MSFT', 'AAPL']);
stream.on('data', (quote) => {
    console.log('Quote update:', quote);
});

// Get historical bars
const bars = await client.marketData.getBarHistory('MSFT', {
    interval: '1',
    unit: 'Minute',
    barsback: 100
});

Order Execution

// Place a market order
const order = await client.orderExecution.placeOrder({
    AccountID: 'your_account_id',
    Symbol: 'MSFT',
    Quantity: '100',
    OrderType: 'Market',
    TradeAction: 'Buy',
    TimeInForce: { Duration: 'DAY' },
    Route: 'Intelligent'
});

// Place a bracket order
const bracketOrder = await client.orderExecution.placeGroupOrder({
    Type: 'BRK',
    Orders: [
        {
            AccountID: 'your_account_id',
            Symbol: 'MSFT',
            Quantity: '100',
            OrderType: 'Market',
            TradeAction: 'Buy',
            TimeInForce: { Duration: 'DAY' }
        },
        {
            AccountID: 'your_account_id',
            Symbol: 'MSFT',
            Quantity: '100',
            OrderType: 'Limit',
            LimitPrice: '160.00',
            TradeAction: 'Sell',
            TimeInForce: { Duration: 'GTC' }
        },
        {
            AccountID: 'your_account_id',
            Symbol: 'MSFT',
            Quantity: '100',
            OrderType: 'StopMarket',
            StopPrice: '145.00',
            TradeAction: 'Sell',
            TimeInForce: { Duration: 'GTC' }
        }
    ]
});

Brokerage

// Get accounts
const accounts = await client.brokerage.getAccounts();

// Get positions
const positions = await client.brokerage.getPositions('your_account_id');

// Stream position updates
const positionStream = await client.brokerage.streamPositions('your_account_id');
positionStream.on('data', (position) => {
    console.log('Position update:', position);
});

Error Handling

try {
    const quotes = await client.marketData.getQuoteSnapshots(['INVALID']);
} catch (error) {
    if (error.name === 'ValidationError') {
        console.error('Invalid input:', error.message);
    } else if (error.name === 'ApiError') {
        console.error('API error:', error.message);
    } else {
        console.error('Unknown error:', error);
    }
}

Resource Cleanup

// Close specific stream
stream.emit('close');

// Close all active streams
client.closeAllStreams();

Quick Start

1. Create a .env file with your TradeStation API credentials:

CLIENT_ID=your_client_id
CLIENT_SECRET=your_client_secret # Optional for public clients
REFRESH_TOKEN=your_refresh_token
ENVIRONMENT=Simulation  # or 'Live'

1. Initialize the client:

import { TradeStationClient } from 'tradestation-api-ts';

const client = new TradeStationClient();

// Get account balances
const balances = await client.brokerage.getBalances('your_account_id');

// Stream real-time quotes
const quoteStream = await client.marketData.streamQuotes(['MSFT', 'AAPL']);
quoteStream.on('data', (quote) => {
    console.log('Quote update:', quote);
});
