What it measures and how

Past pivots are precedent. This study extends the latest confirmed swing high and low as horizontal references, then draws sloping projections through the last two confirmed highs and lows. It separates an established price level from a projection that updates as new structure enters the record.

Get started

1. Install the complete thinkScript through Charts → Studies → Edit Studies → Create in thinkorswim desktop and apply it to your price chart.
2. Load enough chart history for the selected pivotStrength. Each pivot requires bars on both sides, and each projection requires two confirmed pivots of the same type.
3. Read the latest resistance and support values in the label, then distinguish the horizontal pivot levels from the light-gray sloping projections.
4. When reviewing a historical pivot dot, account for the later bars needed to confirm it. The dot's location is not the time when the pivot first became knowable.

How to read it

A level has to earn its placeA candidate pivot high must match the high across its full two-sided window; the low uses the equivalent minimum test. The study evaluates that candidate only after the required bars on its right exist.

Levels and projectionsHorizontal lines use the latest confirmed pivot prices. A projection takes the slope between the last two confirmed highs or lows and extends it forward from the most recent pivot.

Reading a new precedentA newly confirmed pivot replaces the corresponding latest horizontal reference and can change the projection's direction. The older pivot's price remains the same, but the active reference is updated.

Know the limits

Pivot dots are placed back on their original candles after confirmation. A historical chart therefore displays information that was unavailable at the turn itself.

Projection lines change as new pivots confirm. They describe the slope of prior structure, not a promised future path.

The active confirmation window uses the current bar's high and low, so a developing candidate can still change before that bar finishes.
