Frequently Asked Questions

What is a footprint chart?▼

A footprint chart (also called a cluster chart) shows the volume of buy and sell orders at each individual price level within a candlestick. Unlike regular candles that only show OHLC, footprint charts reveal the internal auction dynamics — where buyers were aggressive, where sellers absorbed, and where imbalances occurred.

Is this replay engine really free?▼

Yes, 100% free. Professional footprint and orderflow tools typically cost $50–200/month (like Jigsaw, Bookmap, or Sierra Chart). This replay engine provides the same functionality at zero cost.

Where does the footprint data come from?▼

Crypto data is sourced from Binance trade streams (tick-by-tick, aggregated into 1-minute footprint candles). Forex and commodities data comes from Dukascopy historical tick data. All data is pre-processed and served via CDN for instant loading.
