Rule sheet
Write conditions in if-then language another person could apply. Replace words like “clean,” “strong,” and “near” with measurable definitions.

Free should not mean assumption-free
CHECK 44A browser replay tool can remove software cost, but research quality still comes from the protocol. Convert the idea into observable entry, stop, target, invalidation, session, spread, and maximum-hold rules before selecting a random historical start.
Record every valid signal, including skipped and ambiguous observations. Keep a development segment for clarifying rules and an untouched segment for confirmation. A free workflow becomes expensive when hindsight, ideal fills, or an incomplete journal produce false confidence.
Write conditions in if-then language another person could apply. Replace words like “clean,” “strong,” and “near” with measurable definitions.
Specify bid-ask spread, commission, slippage scenario, financing where relevant, and how same-bar or gap fills are handled.
Develop on one period, freeze the rule, then evaluate a chronologically later holdout without tuning.
The software can be free; reliable evidence still costs attention, restraint, and a complete ledger.
| Field | Question the rule must answer |
|---|---|
| Information set | Which completed bars, indicators, events, and higher-timeframe values are available at the decision? |
| Entry | What observable condition creates an order, when does it activate, and on which quote side? |
| Risk | How are invalidation, position size, correlated exposure, and maximum open risk calculated? |
| Exit | How are stops, targets, time exits, partials, gaps, and same-bar collisions handled? |
| Scope | Which instruments, timeframes, sessions, events, and no-trade states are eligible? |
| Costs | What spread, commission, slippage, swap, and latency assumptions apply? |
Keep trade or opportunity count, confidence or resampling interval, maximum drawdown, time under water, payoff distribution, cost share, and largest-outcome concentration beside any average. A positive point estimate without uncertainty is not a finished result.
Historical replay cannot reproduce unknown intrabar paths, future liquidity, exact live fills, platform outages, or behaviour under financial loss. It can still reject vague or fragile rules cheaply when the process is auditable.
Useful free experiment: test one narrow rule on a development segment, write one-page findings, and run one untouched holdout before adding any filter.
