Precision Problem/Question

[dkrumholz]

In my indicator I have an the if condition if(Low[0] < target).

Target has been calculated as follows:

entryPrice = Open[0];
target = entryPrice - (targetticks * TickSize);

entryPrice is double
target is double
targetticks is integer

My if condition is returning true even though I believe that Low[0] and target are equal.

When I print target and Low[0] to the output window they show the same value. Is it possible that there is a precision problem?

Hi dkrumholz,

There could be a floating point issue, but likely has to do with using integer type in double calculations.

You can cast this is a double for your calculation with something like this:
target = entryPrice - ((double)targetticks * TickSize);

To investigate potential floating point issue, please see the following:

Have you tried rounding your target to ticksize?

Thanks for the suggestions. Converting and rounding all priced based variables to tick based variables should eliminate the problem.
