TraderInput Research / questions before conclusions

A GOOD IDEA
CAN FAIL
A GOOD TEST.

A convincing chart is a starting point. Research asks what remains after the rule is defined, costs are included and observations that disagree are kept in the sample.

CHALLENGE
THE ASSUMPTION.

These are open questions and suggested methods. They are not published performance results.

01 / Order flow

Does positive delta mean buyers are winning?

Define the delta interval and what “winning” means. Compare aggressive buying with subsequent price progress at a preselected location. Keep high-delta failures and quiet advances.

Understand the observation

02 / Market structure

When does a breakout deserve the name?

Specify the boundary, the required distance and the observation window. Compare a brief excursion with sustained activity outside the range before changing the definition.

Define the reference

03 / Execution

Does a good signal remain a good trade?

Record the decision time, available entry, invalidation and costs. Test whether a delayed entry changes the result instead of assuming the original chart opportunity remains available.

Examine the execution

Before inspecting the result

WRITE A TEST
THAT CAN
DISAGREE.

Define the sample.

Record the instrument, contract, dates, session, timezone, source and exclusions. Consecutive observations help prevent a collection of memorable charts from becoming the whole argument.

Define the rule and the comparison.

Write the exact event and what would count as failure. Specify what you compare it with. Record every revision so that a rule discovered after inspecting the data is not presented as a prior prediction.

Account for execution.

Include fees, spread, slippage assumptions and plausible fills. A chart touching a limit is not proof that an order would have filled.

Keep evaluation separate.

Use later or otherwise untouched observations to evaluate the idea. A sample used repeatedly to choose rules no longer provides independent confirmation simply because it is renamed.

State what remains unknown.

A small sample, missing records or sensitive assumptions limit the claim. A descriptive relationship does not establish causation or a dependable future return.
