Three Day Pivot Range

ThinkScripter — Mon, 23 Feb 2009 02:10:36 +0000

Here’s another reader request. The three day rolling pivot range. The pivots are calculated using 24 hour data (vice normal hours) which appears to be a limitation of ThinkScript’s high() and low() functions. If anyone knows a workaround, I’d love to hear it.

The formulas for the high and low pivot range are as follows:

The Pivot= (3day High + 3day Low + Close)/3
The Midpoint= (3day High + 3 day Low)/2
Pivot Range= Absolute Value (Pivot – Midpoint)
Pivot High= Pivot + Range
Pivot Low= Pivot – Range

This script plots the highest regular-hours high, lowest regular-hours low, and midpoint pivot at each bar.
