Questions

Before you try it.

Can I see the next candle before I decide?

No. The replay draws each bar as it happens, and a stop or target only fills once the price reaches it.

How much can I backtest for free?

Any day from the last 30 weekdays, with 3 replays a day. The Trader plan goes back a year with no daily limit, for $29 a month.

Can I test the same rules automatically?

Yes, if you can write them down exactly. Run them as a strategy in the backtester.

Which markets can I replay?

US stocks and ETFs.
