Quick start
Two complete runs in five minutes: one traded by hand, one run by the assistant.
Two complete runs, both short: one you trade by hand in the replay, one the assistant runs from a sentence. Neither needs a paid plan, and everything after this chapter fills in the details.
Run 1 — backtest a chart by hand#
- On Home, press New backtesting.
- In the dialog, pick one asset and keep the window short — a month is plenty. Leave the costs as they are; the next chapter is about them. Press Start.
- The chart opens in replay. Press Space or hold → to move the clock, then use Buy or Sell in the replay bar, with a size in the box beside them.
- Let a few bars pass, then open the position's row menu in the Positions panel and choose Close.
- Skip past the end of the window, or keep stepping. The replay finishes with a settlement dialog — press Open report.
That is one complete manual backtest: a window, two orders, an exit, and a report with its P&L, return, drawdown and win rate — plus the assumption row that says what those numbers mean.
The whole manual loop in one take: press Space, place a Buy with the size box, advance a few bars, close the position from the row menu. Crop to the chart plus the replay bar and positions panel.
Run 2 — let the assistant backtest one#
- Back on Home, check the composer is in agent mode.
- Describe a strategy in one line. For example: "Test EURUSD daily: go long when the 20 EMA crosses above the 50 EMA, exit on the opposite cross, 1% risk per trade."
- Send it. The reply is a spec card — the entry and exit rules it understood — with Run backtest on it.
- Press Run backtest. A result card comes back with the metric grid and the assumptions it ran under.
- Ask a follow-up — "add a 2% stop", "why did 2022 go so badly" — and the next card builds on the last.
That is one complete automated backtest: a sentence, rules you can read, a run over the whole window, and a result. Same engine and same cost assumptions as the manual run you just did.
One result card, whole: the assumptions line at the top, the metric grid, then Trades (N) and Open in chart. Use a run with enough trades to fill the grid.
Where to go next#
The two runs are the product in miniature. Pick the chapter that matches what you want to do next:
- Charts and replay — the chart, the replay bar, layouts and ticks
- Manual backtesting and sessions — costs, order lifecycle, reading the report
- The AI assistant — spec cards, trades, stability readings, credits
- Strategies and indicators — keep the rule, version it, export it
