Binance
The world's largest crypto exchange by volume, used by predtools bots as a primary real-time price feed via WebSocket for BTC and ETH signals.
Definition
Binance is the largest centralized cryptocurrency exchange by trading volume. It publishes real-time trade data via WebSocket streams, including per-trade prices, 1-minute kline (candlestick) data, and order book snapshots. Its high liquidity and low latency make it the preferred price feed for algorithmic strategies that need fast signal generation.
In practice
Poly5m-v1, v2, and v3 subscribe to Binance's WebSocket trade stream for BTC/USDT or ETH/USDT to detect price momentum within the 5-minute market window. The ATR (Average True Range) for volatility sizing is also fetched from Binance's REST API. Poly5m-v4 uses a multi-exchange median (Binance, Coinbase, Kraken) to align with Chainlink's aggregation, reducing the risk that a Binance-specific price anomaly triggers a false signal. Volume imbalance signals remain Binance-only due to its data depth.
