If I manually draw a trendline on a chart, is there a way to reference that trendline within a strategy?

This may or may not pick up trendlines. But it is something worth checking out.Comment

Thankfully it's already handled.
I hacked up the PKPriceAlert2.
The usage of "Value" was incorrect in the post I referenced earlier. I'm sure I compiled that on my desktop at some point, but I can't find it. Wait - that was in NT 6.5. Now I remember.
I unknowingly upgraded this to NT7 version.
