x = iif(h == hhv(h, 30), 1, 0);
y = barssince(x and not ref(x,-1));
As a non-programmer, can someone explain the 2 lines of code in plain
english?
If I correctly understand it, the 1st line will return a 1 if the
argument h==hhv(h,30) is true and a 0 if it isn't. However, what
confuses me is why the iif statement is needed in the first place.
Shouldn't the 1st line simply say x = h == hhv(h, 30)?
Also, what does "and not ref(x,-1))" mean in the 2nd line?
Apologies for the very basic question...
