Sensitivity
Inspect how nearby parameter settings change results. A sharp performance drop deserves investigation; a stable region is useful evidence, not proof.
Your research workspace
Choose parameters with evidence.
Compare parameter sensitivity, walk-forward results and holdout evidence. Inspect confidence and trade counts alongside performance.

Read the process behind the selected parameters.
Walk-forward testing
Read the training and evaluation dates, trades and results for each window. Short histories and sparse trading can leave too little evidence for a confident conclusion.
Holdout evidence
Inspect the reserved-period result separately from the optimization fit. Repeated changes after seeing test results can weaken their independence.

Check the inputs
Data availability, instrument history, fees and fill assumptions vary by venue. Review the coverage and assumptions recorded for your run.

Backtests simulate the past. Paper trading adds forward observations. Low-confidence results are not statistically proven, and neither is a promise of returns.
