i have attached indie Pollan.mq4.
The problem with this language, is the point that vendors, traders who post their code, invariably use the language to enable the indicator to cheat, i.e., repaint, such that results are flawed, deliberately!
That's a constant problem.
Now here again, re the indicator pollan attached. Looking at the code, can a competent coder tell me how many bars of lag this indicator has when it crosses 0, i.e., when it crosses 0, and repaints, did it cross 1 bar or 2 bars later or even more?
