Overflow Error. "Please check 'OnBarUpdate' or 'Plot' Method"

[kcsystemtrader]

On a custom indicator I've built, I occasionally get the following error:

Error on plotting indicator 'MyCustomIndicator'. Please check the 'OnBarUpdate' or the 'Plot' method: Overflow error.

The indicator is an adaptation of the HeikenAshi indicator. I have made no changes to the plot method from that indicator. In OnBarUpdate, all I have is if(Historical), set some values to 0, then return, or if(CurrentBar < 1) return.

I'm overriding onMarketData as that is where most of the indicator logic is. Could the overflow error be generating from this method instead of just OBU or Plot as the log message indicates? What does overflow error actually mean? Memory issue? Thanks

Hi kc,

It will be caused when you perform calculations that result in overflow.

First step is to isolate what value exactly is causing the exception. For this, Try-Catch blocks may work for you:
