Hello bofygym7,

Thanks for your post.

There is no means to enter based on a color change.

The indicator does not expose the series that is being used to determine the color change: private WMA wmaDiffSeries; By keeping it private the Strategy builder or any Ninjascript would not have access to the color change criteria.

Looking at the code for the color change, it looks like they are doing a simple check to see if the plots current value is greater than the previous value: if(wmaDiffSeries[0] > wmaDiffSeries[1]) the plot would be green, otherwise the assumption is that it is Red.

You could do this same type of check in the strategy builder by comparing the current bar of the indicator to the previous bar of the indicator.
