Overflow Error

[molecool]

I'm getting the following error when performing log and other math calculations:

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

What could cause this to happen? I am plotting pre-values nicely but suddenly I get this error after adding a Math.Log(myval) to the data to be output.

Thanks.

Additional info

It seems I'm getting those errors when performing a Math.Log call on my data, for example:

double logged = Math.Log(myVar);
mySeries.Set(logged);

Prior in my code I am also performing various log operations and have observed strange behavior. I am only passing it absolute data and I am observing negative values in the logged data when plotting it. That should be impossible, correct? When handing a set of positive vars to a Math.Log function it should only produce positive numbers.

Any input/help welcome.

molecool,

Have you tried this on a very very simple indicator with only those two lines? What is the value of myVar?

No, I haven't - the issue here is that the log function works fine the first two or three times. But as you add more Math.Log operations at some point things start breaking. I am not sure as to why this is happening - perhaps it's some internal pointer problem, who knows.

I'm sure however that it would work fine in a simple script. But in general - math operations like this should not break no matter what.

BTW, the value of myVar is just a double below 10.0.

Huh? Please consult the MS docs to understand that you e.g. can't create the Log() of a negative value.

Yes, of course I am actually testing for that - I'm not a complete noob. The strategy I'm migrating has successfully run for over a year in ThinkOrSwim. Checking for negatives is kind of essential when performing log operations.

myVal > 0 ? Math.Log(myVal) : 0;

You know - if you're treating me like a noob I might as well not bother help you test your beta. I used to write software for 20 years before I retired and started trading - used to be director of technology for two companies and I am currently CTO at a firm I started. So, you might not want to jump to conclusions unless it's clearly established that I don't know what I'm talking about.

molecool,

Please provide an as simple as possible reference we can use that highlights your issue. Thank you.
