Reduce hindsight bias
A progressive chart keeps the final outcome out of view while you analyze and act.
Manual backtesting that preserves the decision
Test discretionary trading rules on historical charts while future candles remain hidden. Record the trade, inspect the result, and refine the process—not the hindsight.

A CLEARER REVIEW PROCESS
Practice decisions without seeing what comes next.
Automated backtests are useful when every rule can be expressed in code. Manual backtesting is different: it lets you evaluate chart context, discretion, and execution choices that may be difficult to automate. ReplayArc provides a controlled environment for that work.
Test visual trading rules
Practice rules that depend on market structure, chart patterns, drawing tools, or multi-timeframe context.
Treat each trade as a decision
Place simulated entries and exits as the replay moves forward instead of marking ideal trades after the fact.
Use results to refine the plan
Review trade history and statistics to find repeatable behavior, weak rules, and inconsistent execution.
HOW IT FITS YOUR WORKFLOW1 2 3 4
From historical chart to repeatable review
Write the rule first
Define the setup, entry, management, and exit conditions before opening the test period.
Choose an unseen period
Start at a historical point where you do not remember the outcome.
Advance only when needed
Use candle closes and the selected timeframe to apply the same decision process on every example.
Review a meaningful sample
Do not judge a method from one trade. Repeat the rules consistently and evaluate the complete group.

Frequently asked questions
What is manual backtesting?+
Manual backtesting applies trading rules to historical data one decision at a time, usually with future price action hidden.
How is it different from automated backtesting?+
Automated testing executes coded rules across data. Manual testing allows visual interpretation and discretionary decisions but requires consistent execution by the user.
Does a profitable backtest guarantee future results?+
No. Historical simulation has limitations and cannot guarantee future performance.
Can I download a trial?+
Yes. ReplayArc offers a seven-day Windows trial.
