What is Coin Sniffer?

Coin Sniffer is a real-time cryptocurrency market screener that monitors 200+ Binance Futures pairs around the clock and alerts you the moment a significant move or anomaly is detected.

How it works

Binance Futures API
      ↓  (live candle data, every minute)
 Go Backend (Railway)
      ↓  calculates indicators + evaluates 17 alert rules
 WebSocket / REST API
      ↓
  Your browser  →  Discord / Telegram webhooks

The backend processes every 1-minute candle for every tracked pair. From those 1m candles it constructs 5m, 15m, 1h, 4h, 8h, and 1d windows in real time. Alert rules run against those windows within milliseconds of each new candle closing.

Key concepts

Screener

The main table showing all tracked pairs with their current price, percentage changes across timeframes, volume, and computed indicators (VCP, Fibonacci levels). You can sort and filter this table to surface what matters to you.

Alerts

When a coin meets a set of conditions for a given rule, an alert fires. Alerts appear in the in-app feed and, if you've configured webhooks, are immediately sent to your Discord or Telegram channel.

Each alert has a 2-minute cooldown per symbol — so you won't be spammed if a coin keeps meeting the same condition.

Alert Types

Category	Types
Surge	5m Bull/Bear, 15m Bull/Bear, 60m Bull/Bear, 60m V2 Bull/Bear
Scout	Scout Bull, Scout Bear
Raid	Bottom Raid V1/V2, Top Raid V1/V2
Whale	Whale Detector, Whale Accumulation, Whale Distribution

Watchlist

A personal list of coins you want to track separately. Alerts can be filtered to show only watchlist coins.
