Overview

Automated backtesting runs your Strategy script on StrategyTune's cloud over the same tick data manual replay uses. Pick a script, instrument, timeframe and date range; the run saves its trades, equity curve and statistics as an automated session.

Where to find it

Everything lives in the Automated tab of the Sessions panel. Each run you launch appears there as a card — queued, running, saving, or finished — and the daily compute time meter sits at the bottom of the panel. Start a run from the New menu; see Running a backtest for the full flow.

What uses your compute time

• Automated backtests. Your Strategy script trades over the chosen range; results land as read-only sessions with a full run report.
• Filters & Signals timeline tracks. When you put a filter or signal script on the backtesting timeline, its output is computed on the cloud over the session's range.
• Equity & drawdown calculation for manual sessions. The platform replays your recorded trades over the full market data to fill in the statistics a browser replay can't compute — see Trading & P&L.

All of these draw on your daily compute time — script compiles are free. See Compute time & limits.

Runs execute in an isolated sandbox with no network access — see Scripts explained.

No look-ahead

Your script only ever sees what the market had shown by that moment. A forming bar is genuinely partial — no run can read a bar's final values before they happened.

Repeatability

Runs are repeatable: the same script version, parameters, instrument, and range over the same recorded data produce the same result. Re-running an unchanged configuration reproduces the saved result rather than discovering anything new.

How it relates to manual backtesting

Manual replay and automated runs are built to be compared: validate a strategy against your own replay of a period you know, then let automated runs cover the ranges you'd never step through by hand.
