This is read-only version of AFL library entry. Ability to add user formulas and comment is only available from members-only area.

DISCLAIMER: Most formulas present in AFL on-line library are submitted by the users and are provided here on an "as is" and "as available" basis.

Description:

AB version 5.08 is used with this formula - please check your version to insure there are no conflicts with new features.
This formula uses Peaks/Troughs to identify pivots for calculations. Pivots may also be identifed by using your mouse to select any point in the chart. Pivots will be located from the point selected using the % you have chosen for the high and low pivots. Parameters provide funtionality for plotting lines forward (on blank chart), plotting full left extensions, plotting price text, shifting text and plotting retracement lines.

Formula:
