I tried but not getting same results.
After converting strategy to indicator I’m not getting same buy-sell signals as original strategy.
I am not clearly understanding the original code as I’m not a programmer. This is important to me. Can some one please convert this code ? I this this is pretty simple but as I’m not programmer i’m not able to do it.
