Read the figure
107.64 lies inside 107.5–108.0. Overlap is one observation, not two independent sources of evidence.
Learning objective
Distinguish a cluster of related levels from genuinely independent information.
Confluence means that selected references lie near one another: for example a retracement near an earlier swing area. Define near using a fixed price tolerance or volatility fraction. Without a limit on grids and anchors, adding enough levels almost guarantees that some will sit close together by coincidence.
Two Fibonacci grids from overlapping moves share many underlying prices. A moving average from the same candles also shares information. Do not multiply claimed probabilities as if these were independent events. Treat the combination as one defined rule and evaluate its outcomes against a simpler baseline.
State a maximum number of grids, anchor selection and a clustering tolerance before viewing future reactions. Study whether the cluster offers useful risk distance after costs, not merely whether a wick touches it. Include cases where the price cuts straight through every nearby level and preserve the original anchors.
Worked example
Illustration: 61.8% retracement is 107.64 and prior support is 107.5–108.0. They overlap under a 0.5 tolerance. This defines one study zone; it does not establish two independent bullish signals or an improved win rate.
Common mistakes
Avoid adding indicators until a trade feels certain. Clusters discovered retrospectively suffer selection bias even when the arithmetic is correct.
Practice
Choose at most two grids and one prior area. Document anchors and tolerance, then compare a cluster rule with the prior-area-only rule using identical samples and costs.
Fibonacci workbench
Enter swing start A, swing end B and pullback C. C must lie between A and B. Retracements start at B; projections start at C. These are reference levels, not trade instructions.
