Built around the replay

The right-hand side of the chart is genuinely hidden. You read, you decide, you step forward.

Core

Candle-by-candle replay

Rewind any market to any date and step forward one candle at a time, or press play and let it run. You only ever see what a trader saw on that day.

38 markets

Forex, index futures, gold, oil, crypto and US stocks, on the full history.

Trade it like it is live

Place the entry, stop and target on the chart. Lot size follows your risk.

Journal and report

Every trade is recorded, with an equity curve and the numbers that tell you if a setup holds up.

Prop firm mode

Practise a challenge under its drawdown and target rules before you pay for the real one.
