Tj,As always, thanks for the suggestion. I will go through each line and verify that any operations involving division are only using variables that are verified to be appropriate for that equation.Part of me wonders, though, whether it's possible any of the built-in indicators could be causing this. You see, I had seen similar errors in the past, and when I took out certain indicators (for example, the RSI and ADX), the errors went away. I never determined why those particular indicators would cause this floating point error though. Tj,As always, thanks for the suggestion.
Allows some control over floating-point exception (divide by zero, overflow, invalid operation, underflow, denormalized number, positive infinity, negative infinity or a NaN) handling for the main program at runtime.

And you would be right. It turns out that the issue had to do with trying to calculate performance-related statistics when there were no trades. I had thought I had programmed a catch for this, but apparently not!Oh for a run time debugger Even a rudimentary one! AS TJ helpfully suggested divide by zero is often the problem so looking for things like zero volume, zero range (h=l), zero trades and other similar occurrences will get you there.

Can become much more difficult to find as the code gets longer.
Going back in time, I always had a problem with mathematics. It was a great subject and I loved it a lot but I only mastered it after practices a lot. I learned that mathematics problems should be addressed systematically and being verbose is not a trick, I learned to solve any problem.
Recently one of reader sent me an email with the title “ Mathematics problem – please help!” and I was a bit scared. I was good at mathematics but not the best. When I opened the email I was relieved as it was Mathematics problem with SQL Server. My friend received following error while working with SQL Server.Msg 3623, Level 16, State 1, Line 1An invalid floating point operation occurred.The reasons for the error is simply that invalid usage of the mathematical function is attempted. Let me give you a few examples of the same. SELECT SQRT(-5);SELECT ACOS(-3);SELECT LOG(-9);If you run any of the above functions they will give you an error related to invalid floating point. Honestly there is no workaround except passing the function appropriate values.
SQRT of a negative number will give you result in real numbers which is not supported at this point of time as well LOG of a negative number is not possible (because logarithm is the inverse function of an exponential function and the exponential function is NEVER negative).When I send above reply to my friend he did understand that he was passing incorrect value to the function. As mentioned earlier the only way to fix this issue is finding incorrect value and avoid passing it to the function. Every mathematics function is different and there is not a single solution to identify erroneous value passed. If you are facing this error and not able to figure out the solution.
Post a comment and I will do my best to figure out the solution.Reference: Pinal Dave. Just in addition, you will have no problem with +ve values on those functions, like1.
SELECT SQRT(5);2. SELECT ACOS(3)3.

SELECT LOG(9);Only number 2 ACOS(3) throws error, because we need to pass floating expression, alas passing the floating expression also throws error, please execute this oneSELECT ACOS(2.555665555)But if execute this oneSELECT ACOS(0.55555), the generated result is found, I meant the error is not thrown. So in case of ACOS fundtion we have to be cautious to choose the value.Thanksspwho. ACOS value, should not be 1–Not working—-select 69.002. ( 57.2958.(ACOS(COS( 0.0174533. 38.27 ).COS( 0.0174533.
