Matches its published chart, but no repeatable relationship was found in the tested market conditions.
Chart match and market reliability answer different questions. Chart match confirms the published chart can be reproduced; verification depends on whether the measured relationship holds across market conditions and nearby settings.
✓ Chart match
Confirmed
The published chart was reproduced closely enough for the market tests to be meaningful. This is a prerequisite, not the final verdict.
! Market conditions
0 of 6 showed a repeatable relationship
Overall relationship: Weak.
Each condition asks whether the measured relationship remained detectable in a different market regime.
✓ Market robustness
Stable
Across 32 tested market series
This checks whether the relationship remained stable when the same indicator was evaluated on other market series.
• Parameter robustness
No direction reversal recorded
Nearby settings were tested with a 30% input change. Multiple nearby settings were tested.
This checks whether the result survives reasonable changes to the indicator inputs rather than depending on one exact setting.
✓ Repainting
None
Closed historical values did not change when later bars were added.
• Signal lag
Moderate
This describes the recorded timing of the indicator signal relative to the measured market move.
The research profile has not yet been published for this indicator. The existing indicator page and authoritative verdict remain unchanged.

A verdict separates reproducibility from market evidence, then asks whether that evidence remains reliable under broader checks.
01
Chart match
Can we reproduce the indicator’s published calculation?
02
Evidence
Does it show a measurable historical market relationship?
03
Robustness
Does that relationship survive different conditions, market series, and nearby settings?
04
Final decision
Verified only when the required checks finish without a blocking result.
Chart match confirms we evaluated the same indicator. It does not prove profitability. Verification depends on whether the measured relationship is reliable and robust.
Verdicts summarize historical measurements. They are not forecasts, endorsements, promises of profitability, or trading advice.
Declared specification
Declared characteristics and source metadata come from the indicator record, not from the engine verdict.

Check glossary
These checks describe different parts of the evidence process; none is a standalone claim of future performance.
Chart match
Checks whether the published chart can be reproduced closely enough for later tests to describe the same indicator; passing it does not establish profitability or verification.
Market relationship
Tests whether indicator values or changes show a statistically supported historical relationship with later returns; it is not a trading strategy or forecast.
Market conditions
Repeats relationship testing across different market conditions to show whether evidence is broad, narrow, or absent; it does not predict the next condition.
Market robustness
Applies the same settings across other market series to test whether the relationship’s direction survives; coverage describes what was tested, not how many series succeeded.
Parameter robustness
Changes nearby numeric inputs to test whether the relationship survives reasonable settings changes rather than depending on one exact configuration.
Repainting
Checks whether values on already-closed bars change after later bars arrive; historical repainting undermines the reliability of historical evidence.
Signal lag
Measures timing delay between indicator changes and price changes; lag describes timing, not predictive power.
