Practicing on an old chart where you already know the market and outcome tricks your eyes with hindsight bias. Bar Replay in 4CM-AI Charts rewinds history so you step forward one candle at a time (a bar is one candle). You can hide the ticker and date in blind mode, and step multi-timeframe grids together without leaking future candles.
Start Bar Replay and step through candles
Click Replay in the top toolbar or press Alt+B to open the floating replay controls near the bottom of your chart.
Select starting point: opens the five ways to choose where your replay begins.
Step forward and Play: step back (
Shift+←), play or pause (Shift+↓orSpace), or step one candle forward (Shift+→).Multi-chart Sync: switch the link icon between this chart alone, same-symbol panels (default), or all panels. Click Intrabar animation to watch each candle form smoothly from lower-timeframe data.
Replay speed: pick a speed from
0.5×to10×, check the replay clock, or click Exit replay (Alt+B).
Five ways to pick your starting candle
Click Select starting point on the left of the replay toolbar to choose how you rewind.
Bar: turns your cursor into scissors so you can click any visible candle as your cutoff point.
Date...: opens a date and time picker in the chart's timezone so you can jump to a past session.
First available date and Random bar: rewind to the start of loaded history, or jump to a surprise historical candle.
Blind chart: launches a fully masked practice session on a random AI-covered symbol.
How does Blind chart remove hindsight bias?
When you pick Blind chart, 4CM-AI Charts loads a random AI-covered market on 15m, 30m, 1h, 4h, or D. It masks the symbol (••••••), timeframe (••), and replay clock (•••• ••:••). You judge each healthy candle breakout and trading zone purely on price structure rather than memory.
Masked symbol and timeframe: keeps the market hidden while you read levels and map your trading plan.
Reveal button: click Reveal when you finish your drill to uncover the real symbol, timeframe, and date.
Step forward: advance candle by candle to test your entry, stop loss, and stepped profit targets.
You can also launch Bar Replay from any logged trade inside AI Trading Journal. The chart opens 12 candles before your entry with your entry, stop-loss, and target lines drawn automatically.
Multi-timeframe practice drill: open a 2-column layout with 4h on the left and 15m on the right for one symbol. Press Alt+B and keep Sync on same-symbol mode. As you press Shift+→ on 15m, the 4h candle updates smoothly without revealing future 4h highs or lows early.
