# Is is possible to automatically to add a study on the trendline?

Hi, guys

I know there are ways to detect the study crossover for multiple symbols with the use of Scan loke the link. I have to manully draw a trendline.How can I atuomaticlly add a study on the trendline I create with Linearry? Thanks.

You can draw a trendline using Plot() function or MoveTo/LineTo programmatically. Just use GOOGLE, it answers all questions. Type "AmiBroker trendline" into google.
