int index_high = iHighest(NULL, 0, TYPICAL_PRICE, stop_candle, start_candle);
What is this TYPICAL_PRICE? On iHighest the third argument must be an ENUM_SERIESMODE. Do you see it? No, then you must code it yourself.

I use this and it works:
int a=0;
int b=20;
iHighest(NULL,PERIOD_M5,MODE_HIGH,b,a);
a and b should be integers representing the count of the bars with the latest bar being 0.
