Overview
Tracking buy and sell events on Pump.fun is crucial for trading bots and market analysis. This guide details how to utilize Solana’s Yellowstone gRPC stream to efficiently capture and parse real-time transaction data, enabling instant detection of token swaps.What you’ll learn:
- Stream Pump.fun transactions in real-time
- Parse transactions with IDL-based parsing
- Identify buy vs sell transactions
- Extract trade amounts, prices, and participants
Architecture
This implementation consists of three key components:- Stream Transactions - Subscribe to Pump.fun transactions via gRPC
- Parse Transactions - Decode instructions and events using IDL
- Identify Buy/Sell - Detect transaction type based on events

Advanced Features
Price Tracking
Track price movements across trades:Copy
Ask AI
const priceHistory = new Map(); // mint -> array of prices
function trackPrice(trade) {
const price = trade.solAmount / trade.tokenAmount;
if (!priceHistory.has(trade.mint)) {
priceHistory.set(trade.mint, []);
}
const prices = priceHistory.get(trade.mint);
prices.push({ price, timestamp: Date.now(), type: trade.type });
// Keep only last 100 prices
if (prices.length > 100) {
prices.shift();
}
// Calculate price change
if (prices.length > 1) {
const oldPrice = prices[0].price;
const priceChange = ((price - oldPrice) / oldPrice) * 100;
if (Math.abs(priceChange) > 10) {
console.log(`\n⚠️ PRICE ALERT`);
console.log(` Mint: ${trade.mint}`);
console.log(` Change: ${priceChange.toFixed(2)}%`);
console.log(` Current Price: ${price.toFixed(9)} SOL`);
}
}
}
// Call in data handler:
if (trade) {
trackPrice(trade);
}
Large Trade Alerts
Alert on significant trades:Copy
Ask AI
const LARGE_TRADE_THRESHOLD = 10.0; // 1 SOL
function checkLargeTrade(trade) {
if (trade.solAmount > LARGE_TRADE_THRESHOLD) {
console.log(` Amount: ${trade.solAmount.toFixed(4)} SOL`);
console.log(` Token: ${trade.mint}`);
console.log(` Trader: ${trade.signer}`);
// Send notification (implement your notification logic)
// sendTelegramAlert(trade);
}
}
Buy/Sell Pressure
Calculate market pressure:Copy
Ask AI
const pressureWindow = {
buys: [],
sells: [],
windowSize: 50 // Last 50 trades
};
function calculatePressure(trade) {
if (trade.type === 'buy') {
pressureWindow.buys.push(trade.solAmount);
} else {
pressureWindow.sells.push(trade.solAmount);
}
// Maintain window size
if (pressureWindow.buys.length > pressureWindow.windowSize) {
pressureWindow.buys.shift();
}
if (pressureWindow.sells.length > pressureWindow.windowSize) {
pressureWindow.sells.shift();
}
// Calculate pressure
const buyPressure = pressureWindow.buys.reduce((a, b) => a + b, 0);
const sellPressure = pressureWindow.sells.reduce((a, b) => a + b, 0);
const ratio = buyPressure / (sellPressure || 1);
if (stats.totalTrades % 50 === 0) {
console.log(`\n=== Market Pressure ===`);
console.log(` Buy Pressure: ${buyPressure.toFixed(2)} SOL`);
console.log(` Sell Pressure: ${sellPressure.toFixed(2)} SOL`);
console.log(` Ratio: ${ratio.toFixed(2)}`);
if (ratio > 2) {
console.log(` Status: 🟢 BULLISH`);
} else if (ratio < 0.5) {
console.log(` Status: 🔴 BEARISH`);
} else {
console.log(` Status: ⚪ NEUTRAL`);
}
}
