Classic and Floor-Trader Pivot Points

Projects the classic floor-trader pivot and two resistance/support pairs for each bar from the previous bar's high, low, and close.
13 min Python + TypeScriptIntermediate
06

Geometric Chart Patterns / Pivots and Levels

Fibonacci Pivot Points

Takes the same (H + L + C) / 3 pivot as the classic variant but places the bands at Fibonacci fractions of the previous bar's range: r1/s1 at 0.382 of it and r2/s2 at 0.618.
13 min Python + TypeScriptIntermediate
07

Geometric Chart Patterns / Pivots and Levels

Camarilla Pivot Points

Anchors its bands on the previous bar's close rather than on the pivot: r1/s1 sit at close ± 1.1 × range / 12 and r2/s2 at close ± 1.1 × range / 6.
13 min Python + TypeScriptIntermediate
08

Geometric Chart Patterns / Pivots and Levels

Woodie Pivot Points

Weights the current bar's open into the pivot, (H_prev + L_prev + 2 × open) / 4, then derives r1/s1 by reflecting that pivot across the previous low and high and r2/s2 by adding and subtracting the previous bar's range.
13 min Python + TypeScriptIntermediate
09

Geometric Chart Patterns / Pivots and Levels

DeMark Pivot Points

Chooses one of three formulas for the intermediate X depending on whether the previous bar closed below, above, or level with its open, then reports pivot = X / 4 with a single band pair r1 = X / 2 - L_prev and s1 = X / 2 - H_prev.

Geometric Chart Patterns / Pivots and Levels

ATR Support and Resistance

13 min Python + TypeScriptIntermediate
13

Geometric Chart Patterns / Pivots and Levels

Pivot Range Width

Measures the central pivot range rather than its bands: bottom is the previous bar's midpoint (H + L) / 2, top is that midpoint reflected through the pivot, and width is the absolute distance between them.
