Every other free instrument in the catalogue has a page above.

  • NAS100
  • SP500
  • US30

Why one click instead of a signup

Almost every backtesting tool puts a registration form between you and the chart, on the theory that an email address is worth more than a first impression. It isn't. If the replay is good, you will know within about ninety seconds of using it; if it isn't, an email address you were pressured into handing over is worth nothing to either of us.

So the chart is the front door. Click any link on this page and you are in a live session on real market history — stepping candle by candle, placing trades, with your work saved from the first candle. An account exists for syncing that work across devices, which is a reason to make one after you have decided the tool is any good.

What "candle by candle" actually protects you from

Scrolling a chart backwards is not backtesting. When the whole day is on screen you already know where price went, and no amount of discipline un-knows it — you will find the setups that worked and skip past the ones that didn't without ever noticing you did. Replay removes the option: you see one candle, then the next, in the order they happened, and every indicator and every detected concept is computed from revealed candles only.

That constraint is what makes the resulting numbers mean something. See the backtesting mistakes that inflate results, and how many backtests it takes before a win rate is distinguishable from luck.

Free means the whole tool

The free tier is not a crippled demo. Every market, every timeframe, every drawing tool, every built-in indicator and every ICT concept overlay is available without paying — what the free tier limits is how far back you can go: the most recent two weeks of history on each instrument. Pro opens the full archive, which is what you need once you are testing across regimes rather than learning the tool.

Where to start

If you already have a method, open the market you trade and start logging. If you don't, start with a rule simple enough to have no wiggle room — the opening range or a Donchian breakout — and run a hundred of them. The point of the first backtest is not to find an edge. It is to find out how a mechanically perfect rule feels during a losing streak, because that is the thing that decides whether you can follow any rule at all.

Then size what you found: the position size calculator turns a stop distance into a position, and the risk of ruin calculator tells you what your measured win rate actually survives.

Pick a market and start

The chart opens loaded, on real history, with nothing to sign up for.
