From the code it seems that you should check the 6th decimalsalexes wrote: Thu Aug 03, 2017 3:30 am I have a strange problem regarding rounding numbers.
I was using the Buy Sell Volume V 1.0 indicator via iCustom but now I wanted to integrate it directly into my indicator.... So I did that.
Below you will find the sourcecode of the indicator and my integration into my indicator.
Here is a picture of the strange rounding:
If I round it via NormalizeDouble it Roundsup 76.5 to 77.0 and 25.5 to 26.
Why are the values different ?
What do I need to do to get the exact same values? ("Note: I can not use IndicatorDigits(0); because for the other buffers i do need the numbers behind the . )

The calculation is exactly the same:
Code: Select all
int BuySellVolume(int offset, int limit){ for(int i=offset; i<limit; i++) { double bullp = MathAbs(iBullsPower(NULL, 0, 1, PRICE_CLOSE, i)); double bearp = MathAbs(iBearsPower(NULL, 0, 1, PRICE_CLOSE, i)); double vol = iVolume(Symbol(), 0, i); double Buyers = (bullp * vol) / MathMax((bullp + bearp),0.000001); double Sellers = (bearp * vol) / MathMax((bullp + bearp),0.000001); ExtVolumesBufferHisto[i]=NormalizeDouble(vol,0); ExtVolumesUpBufferLine[i]=NormalizeDouble(Buyers,0); ExtVolumesDownBufferHisto[i]=NormalizeDouble(Sellers,0); } return(0); }
Do that and it should be clear
