Reticle: Structural reversal grid — free, open-source

Auto-detects the dominant swing, subdivides it into an 8×8 fractional lattice, and marks the 50–62.5% retracement band as the zone continuation entries tend to hold.

Retracement tools usually stop at a handful of Fibonacci ratios. Reticle goes further — it auto-anchors to the dominant swing (A to B), then subdivides the move into a full 8×8 fractional lattice rather than a fixed ratio set. Inside that grid, the 50–62.5% band is highlighted as the Golden Exhaustion Box — the zone where trend continuations most often resume — while a diagonal Death Line marks the point structure invalidates if price closes through it. It is a free, open-source read on where a pullback is likely to end and where it is proven wrong, with nothing hidden in the code.

Timeframe: Intraday to swing, with a multi-timeframe read for higher-timeframe context.
