Test, review, repeat
What is this concept?
Testing turns an idea into explicit rules, data and a review process. Simulated decisions must use information available at the time. Future closes and later-confirmed pivots can leak into results.
Step by step
Freeze entry and exit rules, document cleaning and timestamps, reserve unseen data and include execution costs. Define conservative handling of ambiguous stop/target bars and compare forward paper observations.
From observation to decision
Record the instrument, venue, session and timeframe. Classify the observation using the definition, then write at least one alternative interpretation. Decide what evidence would invalidate your idea before entry. Mark missing information explicitly. Examples are hypothetical. Collect paper observations, including failures. Include fees, spread, slippage and timestamp alignment when measuring outcomes. Recognizing a chart shape and establishing a profitable trading rule are separate tasks.
Worked example
A 15M close above the previous high can trigger entry at the next open. Assuming frictionless entry at the signal close is a different experiment. Changing rules after selecting the better result requires fresh evaluation.
Common mistakes and limits
Do not call a tuned period final proof, delete failures or use future-known levels.
Practice
Write a one-page rule sheet and log thirty timestamped signals in an unseen month. Record each parameter change and its reason.
