Rule invariance
Keep the economic hypothesis fixed while converting lookbacks, stops, targets, and sizes into defensible instrument units.
A strategy that transfers across instruments may reflect a broader mechanism, but only if the implementation preserves comparable information and risk. Reusing identical point values usually fails that test.
The protocol separates portability from a search for whichever historical asset happened to win.
Cross-asset testing multiplies the search
FIELD 23Applying the same numeric stop and target to forex, indices, metals, and crypto does not test the same strategy. Instruments have different prices, volatility, tick values, hours, feeds, costs, and gap behaviour. The common element should be an economic rule expressed in volatility or account-risk units.
Fifteen assets also create a multiple-comparison problem: some will rank well by chance. Predeclare the universe and selection rule, use matched dates, translate contracts and costs separately, and reserve later periods for every candidate rather than confirming only the historical winners.
Keep the economic hypothesis fixed while converting lookbacks, stops, targets, and sizes into defensible instrument units.
State why each asset is present, delisted or missing. The available archive is not the complete investable market.
Ranking many assets guarantees apparent leaders. Adjust inference and test selected candidates on untouched dates.
Cross-asset portability is evidence about a mechanism only when units, data, costs, and selection are controlled.
Write the rule in terms that can transfer, such as prior-range breakout, volatility-scaled stop, fixed account risk, or percentile threshold. Document any instrument-specific translation and reject an asset when required information is unavailable.
Freeze the asset list, source feed, common dates, timeframe convention, event exclusions, and account currency. Include no-trade assets and failed data mappings in the result; do not replace poor performers after viewing them.
Report uncertainty and net performance for all assets, then account for the family of comparisons. Select candidates using a predeclared rule and evaluate every selected candidate on later dates with unchanged sizing and costs.
