AtCommentaryBar

This reserved word returns a value of True on the bar clicked by the user. It will return a value of False for all other bars.

This allows you to optimize your trading strategies, analysis techniques, and functions for speed, as it will allow PowerLanguage to skip all commentary-related calculations for all bars except for the one where the commentary is requested

Usage

AtCommentaryBar

Notes

• The difference between AtCommentaryBar and CommentaryEnabled is that CommentaryEnabled returns a value of True for ALL bars when the Expert Commentary window is open, while the AtCommentaryBar returns a value of True only for the bar clicked.

Example

The following statements display a 50-bar average of the volume in the Expert Commentary window but avoid calculating this 50-bar average for every other bar of the chart:

if AtCommentaryBar = True then 
    Commentary("The 50-bar vol avg: ", Average(Volume, 50));
