In three sentences
  • Equal highs and lows are clusters of swing extremes that sit within a tolerance band of each other.
  • The engine groups swing pivots within 0.25 x ATR(14) and treats the cluster as one liquidity pool.
  • A cluster stays on the map only while untapped; once price trades through it, it is gone for good.

What it is

When price turns at nearly the same level twice, chart-drawing tradition calls it a double top or double bottom and treats it as a wall. This engine reads the same picture differently: two rejections at one price means two batches of stop orders parked just beyond it. That is not a wall — it is fuel.

Mechanization v1 Confirmed swing pivots of the same kind are clustered when they sit within 0.25 x ATR(14) of one another; the cluster's mean price becomes one level on the liquidity map, alongside prior-day and prior-week extremes. A level is dropped as soon as price trades through it (tapped), and only untapped levels can arm a setup.

Why the tolerance matters

Set it too tight and equal highs almost never form; set it too loose and every wiggle joins a cluster until the chart is wallpaper. Tying it to ATR means the same rule behaves consistently on a quiet BTC afternoon and a violent SOL session, which is what lets one parameter serve eight markets.

Common misuse

Treating the level as a target in itself. In this engine a cluster is only interesting when it is swept and the structure answers — the pool is where the move begins, not where the trade ends.

Common questions

How equal is equal?

Within 0.25 x ATR(14) of each other. Absolute equality never happens on real charts, so the tolerance scales with volatility rather than being a fixed number of points.

Why do these levels attract price?

The premise is behavioural, not mystical: a visible double top is where stop orders accumulate, and resting orders are what large participants need in order to fill. Whether that premise pays after costs is what gate G2 tests.

Do equal highs guarantee a sweep?

No. Most mapped clusters are never swept at all, and plenty get broken outright. The map is an inventory of possibilities, not a forecast.
