⚠ Model-based estimate, not actual exchange data.
Historical storage: All data is stored in monthly files under data/history/. Over time the model becomes more accurate as more history accumulates.
Model vs Display: The chart shows the last displayDays of candles, but the model calculates on modelDays of data for deeper inventory buildup.
Incremental fetch: Only new data is fetched from Binance. Use Force to refetch everything.
Cron: ?api=cron&symbol=BTCUSDT&tf=5m — fetches newest data, stores in monthly files.
Heatmap API: ?api=heatmap — returns liquidation levels in compatible JSON format (from stored data only, fast).
Settings: Changes are applied live. Click Save to JSON to persist. The API always uses saved settings.
