    • Example of a Node.js integration using webhooks:
      javascript

      const Binance = require('node-binance-api');
const express = require('express');
const app = express();

const binance = new Binance().options({
  APIKEY: 'YOUR_API_KEY',
  APISECRET: 'YOUR_API_SECRET'
});

app.post('/webhook', (req, res) => {
  const alert = req.body;

  // Example: Execute a market order based on TradingView alert
  if (alert.action === 'buy') {
    binance.marketBuy('BTCUSDT', 1);
  }

  res.json({ message: 'Order executed' });
});

app.listen(3000, () => {
  console.log('Webhook listener running on port 3000');
});

Summary of Technologies:

  • JavaScript: Primarily used for web integrations with TradingView and Binance. Ideal for embedding charts and using the Binance API.
  • Python: Used for backend integrations, automated bots, and technical analysis calculations. Ideal for creating custom logic and integrating with TradingView alerts.
