I think this is the result of the indicator.. (red Line)

I’m not sure because the SierraChart language is very, very difficult and I’m programming whit it from 5 days..

I would have preferred to continue the studies on proreal .. maybe if the problem with the v11 is solved it would be excellent..

News from Nicolas?

This the Sierra code:
