also,
if(iHigh(NULL,0,xi) ==1.32){ZV = true;}
it does not work, too
Im confused.
I wrote something in loop script and encountered a wired thing.
if(iHigh(NULL,0,xi) == levelnum) {ZV = true;}
it does not work.

Im confused.
I wrote something in loop script and encountered a wired thing.
if(iHigh(NULL,0,xi) == levelnum) {ZV = true;}
it does not work.
first check:
if(1.32 == 1.32){ZV = true;}
It works.
if(1.32 == levelnum){ZV = true;}
it works.
if(iHigh(NULL,0,xi) == levelnum){ZV = true;}
It does not work...
so I printed all values of iHigh to check
1.3300000
1.3200000
1.3100000
1.3000000
What is wrong? Thank for your helps!
I'm amazed that you found 4 bars that had such convenient highs, are they really iHigh values?
As you don't show the loop, it's difficult to say, but is it possible that ZV is true for one cycle of the loop and then reset to false on a subsequent cycle?
