Create Your Own Trading Bot

Xtreders webhooks make it easy to build custom trading automation. This guide shows you how to create a basic trading bot that reacts to price alerts.

Architecture

The flow works like this:

1. You create a price alert on Xtreders with a webhook URL pointing to your server
2. When the price condition is met, Xtreders sends a POST request to your URL
3. Your server receives the alert data and executes a trade via your broker API

Example: Node.js Webhook Receiver

const express = require('express');
const app = express();
app.use(express.json());

app.post('/webhook', (req, res) => {
  const alert = req.body;
  console.log('Alert received:', alert.symbol,
              alert.condition, 'at', alert.trigger_price);

  // Your trading logic here
  if (alert.condition === 'crossing_up') {
    placeBuyOrder(alert.symbol, alert.trigger_price);
  } else if (alert.condition === 'crossing_down') {
    placeSellOrder(alert.symbol, alert.trigger_price);
  }

  res.status(200).json({ received: true });
});

app.listen(3000, () => console.log('Webhook server running'));

Example: Python Webhook Receiver

from flask import Flask, request, jsonify

app = Flask(__name__)

@app.route('/webhook', methods=['POST'])
def webhook():
    alert = request.json
    print(f"Alert: {alert['symbol']} {alert['condition']} "
          f"at {alert['trigger_price']}")

    if alert['condition'] == 'crossing_up':
        place_buy_order(alert['symbol'], alert['trigger_price'])

    return jsonify({'received': True})

if __name__ == '__main__':
    app.run(port=3000)

Security Best Practices

• Verify the X-Alert-Id and X-User-Id headers
• Use HTTPS for your webhook endpoint
• Validate the payload structure before executing trades
• Implement idempotency to prevent duplicate trades
• Add logging for all received webhooks and executed trades
• Set position size limits in your bot to prevent accidents

Testing Your Webhook

Before going live:

1. Use a service like webhook.site to inspect incoming payloads
2. Create a test alert on a demo account
3. Verify the payload format matches your parser
4. Test error handling (what if your server is down?)
