MOMENTUM INDICATOR
Relative Vigor Index
Compares close-open movement with the high-low range and smooths the result.
Start with the input, not the story.
Whether closes tend to finish above or below opens relative to range.
Plain-language formula
Smoothed close-open divided by smoothed high-low, usually with a signal line.
Platform implementations can differ in price input, smoothing, indexing and rounding. Record the exact settings and provider before comparing results.
03 / USEFUL REGIME
Where it may help

04 / WEAK REGIME
Where it struggles
Thin or erratic bars and rules based only on line crosses.
Add a different measurement.
Trend filterATR
A complementary tool should answer a different question, such as volatility, regime or position risk. Test the base rule before testing the combination.
The shortcut to avoid
Adding it beside several other price-derived momentum oscillators.
A testable next step
Compare it directly with RSI and MACD to detect redundancy.
