My indicator draws multiple pair's daily percetage change as line in the indicator window.
However I noticed a very weird problem, that the value are sometimes wrong as the ticks goes by on chart, but if I refresh or reload the indicator,
the value goes back to the correct value. But this does not happen in the strategy tester using everytick mode, everything is correct there when I ran the indicator.
You could see this happening if you put it on the M1 chart and let it tick for a few bars then reload the indicator.
Have anyone ever encounter such problem? Any help would be appreciated. Thanks in Advance.
Below are the codes:
