Hi all,
I hope this is the right place to post this - apologies otherwise & please redirect me to the right place.
I'm trying to filter some signals using a for loop.
I print the variables in the loop and I 'plotShapes' the same variables. Results are erratic and inconsistent.
If I move the selection bar, the values printed with printf do not match what is displayed with plotShapes, and both seem to be incorrect [they do not reflect the code in the loop, in some instances].
I use this on EUR.USD-IDEALPRO-CASH , 1 min chart, but the same problem happens with other tickers and timeframes. I use Amibroker 5.24 beta, but it happens with 5.20 as well.
Has anyone encountered this before? What could be the problem?
Thank you,
Alex
Here's the code, with a few debug aids included:
