Use Case
Bar Replay in GoCharting replays historical price data bar by bar, simulating real-time market conditions. It allows traders to practise reading price action, test indicator setups, and validate trading strategies on past data without risking capital.
Strategy
Use Bar Replay to practise your entry and exit criteria on at least 100 historical setups before trading live. Play back significant market events and practise your reaction to them. Test how your indicators and alerts would have performed during recent volatility events.
Common Mistakes
Do not treat Bar Replay results as a perfect prediction of future performance — hindsight bias affects how you react to bars you have seen before. Avoid only replaying setups that worked; study your failures equally. Do not skip Bar Replay as a preparation step before live trading a new strategy.
