Re: Trendline - Strange results

["akaloustian" <ara1@xxxx>]

Stephane,

Thanks for the quick reply.

I was using the DLL inproperly. The code is now works OK with my 
indicator, with one exception.

I still have a problem with the first point of the trandline 
(endpoint). The trendline array is empty at the end point, so the 
point takes the value of the next bar, producing a horizontal line 
for 1 bar, then the line is correct.

Any suggestions?
