Import your actual history to begin. A three-year date range is checked against the timeframe and supplied session schedule.
Obtaining a three-year dataset
Export your permitted historical data from your chart provider or broker. Keep the instrument, timeframe, quote side and candle opening-time convention consistent. A provider’s export may contain only the bars available under your plan. Request missing periods from that provider and inspect its session calendar before describing the dataset as complete.
Checksums identify file bytes. They do not establish that the prices are accurate or grant redistribution rights. This library stores your imported files on this device; no public historical dataset has been supplied.
