Card 1
Organize the research hypothesis
Turn market observation into a describable research hypothesis.
Card 2Define rules
Translate the hypothesis into conditions that can be checked, recorded, and reviewed.
Card 3Controlled-testing workflow
Check whether signal, record, and review workflows are consistent in a test setting.
Card 4Review and iteration management
Record issues and gradually improve the research framework through cause analysis.
PROCESS
Six stages of strategy research
Form a hypothesis
Translate a market observation into a describable research hypothesis.
Define rules
Break the hypothesis into data, conditions, signal records, and invalidation boundaries.
Review samples
Observe result distribution, drawdown size, and signal count in historical samples.
Check process
Check whether signal generation, records, and review mechanisms are consistent.
Review under limits
Review rule behaviour and risk boundaries under defined research conditions.
Manage revisions
Record causes and improve the research framework by version.
PROCESS CHECK
Process differences in the same range-observation rule
Before subsequent monitoring, workflow differences, delays, record completeness, and market-state changes still need consideration. Historical analysis is only the first step; controlled testing and human review remain necessary.
FAQ
Three common beginner questions
If historical analysis looks positive, will the future be stable?
Not necessarily. Historical analysis checks logic; subsequent monitoring is affected by costs, slippage, delay, and market-state change.
How does controlled testing differ from later conditions?
Test settings are often more standardised, and records can be more idealised. They are only one research step.
What should controlled testing focus on?
Focus on sample count, signal quality, workflow stability, and abnormal records instead of short-term results alone.
Turn vague observations into research questions
Strategy research usually starts from a describable market observation, for example:
- Price shows continuity near certain ranges.
- Price may return to a normal range after a large deviation.
- Volume changes may strengthen certain observation signals.
- When volatility is too low, rule samples may have limited reference value.
These observations are often broad at the beginning, so they need to become verifiable questions: what data is observed, what counts as condition fulfilment, what counts as condition failure, which market states should be excluded, and whether the hypothesis is worth further study.
Translate hypotheses into verifiable conditions
After organising a hypothesis, it must be translated into specific rules. Program review and historical sample testing both require clear conditions; vague statements cannot enter a review workflow.
For example, “the market is strong” should be further defined as observable conditions. “Volatility is high” should also be expressed through an indicator, range, or sample statistic.
Rule definition usually includes observation data, record conditions, observation-exit conditions, filters, risk limits, and pause conditions.
The clearer the rule definition, the easier it is to review, record, and locate issues.
Verify workflow consistency before evaluating sample behaviour
After rule definition, controlled testing should check basic workflow issues:
- Whether signals appear according to the rule.
- Whether invalidation or exit conditions trigger normally.
- Whether risk boundaries are effective.
- Whether data updates are stable.
- Whether duplicate or abnormal signals appear.
- Whether records are complete.
The focus of controlled testing is workflow consistency, record completeness, and exception handling, not short-term results. Problems found during testing are easier to correct with lower cost.
Use records to drive framework iteration
After a strategy enters controlled testing, ongoing review is required. Review records sample behaviour, workflow issues, and abnormal states. Common review items include:
- Whether signals match the rules.
- Whether sample behaviour matches expectation.
- Whether risk boundaries are triggered.
- Whether abnormal data appears.
- Whether duplicate signals appear.
- Whether sample behaviour differs across market states.
Iteration should not be casual. Each revision needs a clear reason, such as dense signals, drawdown pressure, insufficient samples, or incomplete filters. A more robust process is: find issue → record cause → propose change → re-review → observe change.
Controlled testing does not represent later behaviour
This module explains the strategy research workflow only. It does not constitute product advice, personal advice, or operational instruction. Controlled testing, historical analysis, and teaching cases are not evidence of future results.
