Hello

Does anyone know why I am getting this error message " FPInvalidException: Floating point invalid numbers in calculation" when I put in a number that's greater than 10 yrs for the data range on the Format Symbol window? The strategy works fine for any range that is less than or equal to 10 yrs.

I know people usually get that error if their code has a divisor = 0, but my issue doesnt seem like it's caused by this.

Thanks

Within the range of data you're trying to plot, one of the calculations within your strategy is trying to return both an extremely small and extremely large value (if indeed you're certain you're not dividing by 0). If your code is well written, conscise, then experiment with replacing segments of complex calculations with whole numbers. For instance instead of value1=myLongFormula use value1=smallPortionOf_myL ongFormula, or if necessary take it all the way to value1=1; But that's the advanced debugging, before that you should try simply commenting out code until you find the likely target.
