Highlights

Selected historical examples

Selected signal highlights.

Real SPY candles, Extreme signals, and the price moves that followed. These two examples show an early top warning and a signal near a bottom.

Chosen after the outcomes were known. They show what happened in these cases, not how often signals succeed.

Price is above; matching Rank bars are below. Positive is overbought, negative is oversold. Triangles mark Ranks that match or exceed the strongest earlier reading on that side of loaded history, not confirmed reversals. Read Rank strength from the bars, not triangle height.

A and C mark the first triangles shown. B and D mark later price moves. Gold letters are added explanations, not indicator signals. All 129 consecutive candles in each view are retained. In the April example, −6 is an unmarked Rank bar; the triangle is at −7.

Dashed ±4 and ±6 lines are strength guides, not Extreme thresholds. No Rank bar means 0. These examples use v11 default settings with the 24H session selected. The April oversold triangle follows the checked publication view with more loaded history; the earlier export marked both bars. Available overnight data varies by date.
