Can someone help me resolve this issue?

Hi,

I have the following codes:-

BP1 = Close[1]-Math.Min(Low[1],Close[2]);
BP2 = Close[2]-Math.Min(Low[2],Close[3]);

and the following output derived from the above codes:-

Close[1] is0.9581
TrueLow is0.9563
BP1 is0.00179999999999991
Close[2] is0.965
TrueLow is0.9632
BP2 is0.00180000000000002

1. Why am I getting solutions to the 17th decimal?
2. BP1 should equal BP2 but in the above, it isn't. How can I resolve this problem so that they will reflect as being equal.

BP1 and BP2 are double values.

Regards

You are handling price data, so you probably want to round your values off to the ticksize of the instrument. That should make them equal, as the difference should be at most a little rounding error caused by the computer computation size structures.

BP1 = Close[1]-Math.Min(Low[1],Close[2]);
BP2 = Close[2]-Math.Min(Low[2],Close[3]);
BP1 = Instrument.MasterInstrument.Round2TickSize(BP1);
BP2 = Instrument.MasterInstrument.Round2TickSize(BP2);

Thanks much Koganam!
