Where is the issue ?

Hi everybody,

Just wondering where is the issue in this little code :

Ninja says "out of range" but I don't get why. My goal is to determine the biggest "drawdown" variation of the RSI since he crosses over the level 30. It means if the RSI do : 30 / 45 / 68 / 60 / and now we're at 70, the biggest Drawdown is 8 (68-60).

if (CurrentBar>200) {

            if (RSI(Close,14,3)[0]>30 && RSI(Close,14,3)[1]<30) {
				Barindex30 = CurrentBar;
		}




            if (Barindex30>0) {
			for (int a = 0; a>=CurrentBar-Barindex30; a++) {
				if (MAX(RSI(Close,14,3), (int)CurrentBar-(int)a-(int)Barindex30)[a]-RSI(Close,14,3)[a]>memoire1) {
					memoire1 = MAX(RSI(Close,14,3), (int)CurrentBar-(int)a-(int)Barindex30)[a]-RSI(Close,14,3)[a];
				}
			}
			}

}

Thanks a lot !

From

a>= CurrentBar - BarIndex30

you obtain

CurrentBar - BarIndex30 - a <= 0

which means that

MAX(RSI(Close, 14, 3), CurrentBar - a - BarIndex30)[a]

is an invalid expression.

Thanks Harry ! I didn't check yet but you got it, it's "<=" and not ">="

thanks a lot !!
