Fisher-Transformed Relative Vigor Index for Timely Reversal Signals

Summary

The document describes the Relative Vigor Index (RVI), which compares a closing price’s position within its price range and smooths the resulting values with an exponential moving average. It frames the indicator as a way to assess the strength of recent price action and the chance that it will continue. The page then adds a Fisher Transform to the RVI, describing the transform as a normalization that makes extreme swings stand out and may help identify potential reversals.

The stated use is to seek timely signals rather than rely on slower indicators. However, the document does not include the promised calculation formula, specify parameters or signal rules, or provide tests showing predictive value. It gives no market, timeframe, or risk-management guidance, so the indicator description alone is not enough to establish when a signal should be traded or whether it is reliable.

Key ideas

• The RVI compares closing prices with their surrounding price ranges and smooths the measure.
• The Fisher Transform is applied to the RVI to emphasize unusually large swings.
• The combined indicator is presented as a tool for spotting possible reversals with timely signals.
• The document omits the calculation details and gives no empirical evidence or trading rules.
