Thanks,
I see as expected that the "least square fit" method is used. Just had to get it confirmed. Source code helps

Hello,
Can you give some details on what method is used to fit a series of data to a straight trend line in the TTrendFunction (TTrendStyle = tsNormal)?
We are using this in our product and have customers who wants to know the method used to generate the trend line.

Thanks,
Kjetil
