An indicator can produce a different wave interpretation after its settings change. A parameter-sensitivity record helps locate that difference. It does not select the setting that will forecast the future most successfully.

Save the baseline

Freeze the input file or chart window, final completed price bar, software version and all relevant settings. Save both the larger interpretation and the smaller turning points. Without that baseline, a later screenshot cannot show whether the settings or the input history caused the difference.

Change only a documented parameter

Choose a parameter the specific tool actually exposes. If its documentation defines a turning-point threshold, compare two permitted threshold values while keeping the data fixed. Do not invent a sensitivity control for a product that does not provide it. Record the exact original and revised values.

Compare structure rather than appearance

In an invented trial, the larger start and endpoint remain fixed while two small turning points disappear. Record the stable boundaries, changed subdivisions and any revised rule checks separately. Similar colors or a tidier chart are not useful measures of structural agreement.

Interpret stability cautiously

Agreement across settings shows stability under that particular test. It does not prove the pattern true or the forecast profitable. Disagreement identifies a part of the interpretation that depends on the chosen setting and may need to remain provisional in the analysis record.

An interpretation survives two settings unchanged. Is its forecast therefore validated?

No. The test establishes only stability under those settings and fixed data. Forecast evaluation requires a separately defined test on later observations.
