my first post here, but i have to say very good site!
I'm working a custom indicator that i have made. So far so good but i can not get values from it older than lets say x bars. Why is that, when i'm reading all bars with Bars-1 function?
Maybe the problem is in Time[i+j] function? Is that possible? Or may be the drawing arrey is restricted some how?
This is a simple correlation indicator. Please take a look at my code:
