Backtests

The backtest tab on Hosting lists submitted runs. Open one for the range, spot or swap, progress, and result. Queued, running, done, failed, and stopped each have their own status.

If stored candles do not cover the window, the run fails and asks you to try another symbol or try later.
Free and paid plans differ in backtest days and runs per day. The membership page states the quota.
A backtest fill is not a future live result.
