Real 1-second market data, replayed bar by bar. Place your orders, watch them fill or stop out, and get a written post-mortem on every trade you lose — not just a number in a column.
Free. No card. Your replay, equity and trade history are yours alone.
A live chart is a terrible classroom: you get a handful of setups a day and no way to rewind. This replays real days at whatever speed you want.
Land at a random moment in real gold futures history, or pick a date. The chart advances one second at a time — step it, or hold play and watch it run.
Market, limit or straddle orders with your own take-profit and stop. Fills are checked against the actual 1-second highs and lows, so a stop that would have been hit, is hit.
Every losing trade is diagnosed — counter-trend, weak level, thin session, knife-catching — with what to have done instead: buy, sell, or stay out.
Levels are clustered from swing highs and lows and rated one to five stars on touch count, RSI, EMA alignment and the hourly trend — so you can find out whether your 2-star trades are quietly funding your 5-star ones.
The same window is backtested automatically, so you can see what the mechanical rules would have made on exactly the days you just traded.
Play a session from the 08:00 open to the 16:50 cutoff, auto-close whatever is still open, then jump to the next day. A month of sessions in an evening.
Close the tab mid-trade and come back tomorrow. Your bar, your open positions, your equity and your history are exactly where you left them.
One good day proves nothing. Trade 100 and the app writes up the whole run: win rate, profit factor, expectancy, max drawdown, your longest losing streak, and a breakdown by setup quality and by direction.
Sessions are kept, so you can see whether you are actually improving or just having a good week. Lose a session and you get a training plan built from your own worst trades — replay the exact setups you got wrong.
Yes. No card, no trial, no paid tier. It is a personal project running on one small server; if it ever needs to cover its costs, existing accounts keep working and you will hear about it first.
Neither. It is recorded historical data and imaginary money. There is no broker, no deposit and no way to lose anything real. That is the point — it is where you make the mistakes.
Gold futures at 1-second resolution, currently a month of GCZ6 with more being added. NASDAQ data is supported by the engine and will follow.
No. It runs in the browser. It works on a phone, though a real chart on a real screen is a much better way to learn.
No. Every account has its own equity, positions, trade history and replay position. Market data is the only thing shared, and it is read-only.
It teaches you one: a support/resistance straddle on gold. The value is less the rules than the reps — and finding out which of your setups actually make money.
