Need help with Momentum

justize:
int pos=Bars-counted_bars;

double dMedian ,dMedian1, dResult;

//----main calculation loop

while(pos>=0)

{

dMedian = (High[pos] + Low[pos]) / 2; //medianPrice

dMedian1 = (High[pos+3] + Low[pos+3]) / 2;

dResult = dMedian*100/dMedian1; //Momentum of medianprice

ExtMapBuffer1[pos] = dResult; //fill buffer with results

pos--; //calc next bar

}

In the beginning, you will find two bars for which dMedian1 would be zero, and I suspect MT4 gets quite uppity with division by 0. Thus, make sure that pos < Bars - 2.

Thank you very much, that was it!

I have coded this now:

while(pos>=0)

{

dMedian = (High[pos] + Low[pos]) / 2;

dMedian1 = (High[pos+3] + Low[pos+3]) / 2;

if (dMedian1 == 0) dMedian1 = 1;

dResult = dMedian*100/dMedian1;

ExtMapBuffer1[pos] = dResult;

pos--;

}

Now it seems to work.
