US stock bar replay
Trade the bar you can see.
Bar Replay is practice for US stock trades on past charts. You buy and sell before the next bar appears, then review the path, your return, and each trade.
The first three sessions need no account. Starting another asks you to sign in, and those sessions stay with that account.
How a session works
01
Start before the ending is visible
A random blind session hides the ticker and the year. Or pick the stock and the dates yourself.
02
Only the current bar is on the chart
Scrolling back cannot reveal later prices. The next candle appears when you step forward.
03
Review after you finish
You then see the path you didn't trade, plus return, max drawdown, win rate, profit factor, and how long each trade lasted.
Built for US stock practice
Train entries and exits on liquid US names and ETFs such as SPY, QQQ, AAPL, and NVDA. The interface defaults to Chinese and switches to English on this page.
