    Is there a discrepancy between the DataSeries and the chart data box?

    I have a data series on a chart. When I hover over a bar, I see a value of 0.0000337. The next bar in the data series is 0.0000278. The 2nd is clearly less than the first. However when I test for a comparison they are considered equal.

    How is the data box from the chart calculating the value different from the actual data series? Clearly those two numbers are not equal right?

    The Data Box will display whatever is in there. Please use Print() of your actual values to debug.

    Print(myDataSeries[0] + " " + myDataSeries[1]);

      What I'm saying is that myDataSeries[0] and myDataSeries[1] are being tested as equal even though the data box is showing them as different values.

      Does this have something to do with the inability for computers to store proper floating point values and the introduction of some kind of rounding errors? That is why I'm wondering how NT is extracting the values to show in the data box, because they are definitely different than what is being reported by the dataseries.

      I tried doing Math.Round(mds[0]) == Math.Round(mds[1]) and that resulted in a false, so there seems to be more than meets the eye here.

        DataSeries are double values, the DataBox will display the same data as displayed on the chart. This value is trimmed to the same number of significant digits as the underlying tick size of the instrument.
