Question about some mql4 code lines

Hi everyone, I have a question about the use of iHighest

A compile results in zero errors.

I want the indicator to place an arrow at the bar that meets the criteria, but it seems the third and fourth condition are not taken into account, so I get arrows at every candle that meets the first two criteria.
if(iMA(NULL, PERIOD_M15, MainTrend, 0, MODE_EMA, PRICE_CLOSE, 2+i) < iMA(NULL, PERIOD_M15, MainTrend, 0, MODE_EMA, PRICE_CLOSE, 1+i)
&& iMA(NULL, PERIOD_M15, 21, 0, MODE_EMA, PRICE_CLOSE, 2+i) > iMA(NULL, PERIOD_M15, 21, 0, MODE_EMA, PRICE_CLOSE, 1+i)
&& iVolume(NULL, PERIOD_M15, i) >= iHighest(NULL, PERIOD_M15,MODE_VOLUME, 100, i)
&& iLow(NULL, PERIOD_M15, i) <= iLowest(NULL, PERIOD_M15,MODE_LOW,50,i)

Can anyone tell me what I'm doing wrong here?

Robert

iLowest() isn't giving the lowest price but the candle shift for the lowest price.

You must write Low[iLowest(NULL, PERIOD_M15,MODE_LOW,50,i)]

The same for iHighest().

Also noticed you are comparing volumes with high ... Not sure what you are expecting here ... Volumes is just a ticks count ... Nothing to do with price itself.

Thanks FerruFX, I will try to get the code right and working with your remarks

enjoy your weekend

Hi FerruFX,

I adjusted the code according to your remarks, and now it works like a charm.

thanks for your help, have a nice day

Great!
