Pricing and plans
Free, unlimited and cancelling
Is CRTLAB free?

Is there a subscription?
Only if you want unlimited replay. CRTLAB is free to try. Your first 10,000 candles of replay are free, roughly two hours with every market, every timeframe and every tool, so you know exactly what you are buying. The sample does not reset. After it, unlimited replay is $14.99 a month and you can cancel any time.
What happens when I run out of candles?
The chart stops advancing and everything else stays exactly as you left it: your session, your drawings, your journal. The sample does not reset: CRTLAB Pro is $14.99 a month and you carry on from the same candle straight away.
How do I cancel unlimited?
From Plan & usage in CRTLAB, any time. Cancelling stops future renewals and you keep unlimited replay to the end of the month you paid for. The refund policy has the details.
The product
Replay, strategies and prop firms
How is this different from paper trading?
Paper trading runs at the speed of the market, so a year of practice takes a year. Replay runs at the speed of your mouse. You can put a hundred trades through a setup in an evening instead of waiting a hundred sessions for them to appear, and you can do it on 2018 as easily as on this morning.
Can I test a strategy I did not code?
That is the point. This is manual, discretionary backtesting: you read the chart, you place the entry, stop and target yourself, and the journal records what happened. If your edge lives in how you read structure rather than in rules a machine could follow, an automated backtester cannot test it and this can.
Can I practise a prop firm challenge?
Yes. Prop firm mode replays a challenge under its drawdown and profit target rules, so you can see whether your strategy passes before you pay for the real one.
Does CRTLAB place real trades?
No. It is backtesting and replay software only. Nothing in it is financial advice and no money is ever traded.
