Ever felt like you’re missing the perfect entry point because you can't stare at the charts 24/7? That was me. Instead of burning out by watching 1-minute candles all day, I decided to build a simple, efficient tool to do the heavy lifting for me.
Today, I’m sharing how I built a real-time BTC/USDT monitor that runs on a VPS and sends smart alerts directly to my Telegram.
🚀 What’s Under the Hood?
I wanted something lightweight that wouldn't consume my server's RAM or spam my phone every second. Here is the stack:
Language: TypeScript
API: CCXT (the industry standard for crypto exchange connectivity)
Indicators: technicalindicators for RSI and EMA calculations.
Deployment: PM2 for 24/7 background process management.
💡 The "Anti-Spam" Logic
The biggest mistake beginners make is sending an alert every single time a condition is met (e.g., every 60 seconds while RSI is > 70). My bot solves this using simple state flags:
TypeScript
let notifiedRsiOver70 = false;
// ... inside the main trade loop
if (currentRsi > 70) {
if (!notifiedRsiOver70) {
await sendTg(⚠️ OVERSOLD: RSI is ${currentRsi.toFixed(2)});
notifiedRsiOver70 = true; // Prevents duplicate alerts
}
} else {
notifiedRsiOver70 = false; // Reset when market cools down
}
🛠 Why Open Source?
I believe that simple tools like this are the perfect "starter kit" for anyone looking to dive into algorithmic trading. You don't need a complex AI model to start—you just need reliable data and smart notifications.
