Detect optimization mode programmatically

Sorry if this has been asked before but I'm finding it a bit difficult to search for.

I have an expert that writes out a lot of information to CSV files. The problem is, if I forget to turn this off before I start optimization, it will write these CSV files for every thread that it uses. These then gobble-up all the disk space and the optimization run fails.

The ideal solution to this would be detecting when using optimization mode or where the EA is running on a thread other than the first thread normally used by back-testing, and then disable the CSV output.

Does anyone know how I can achieve this?

Documentation on MQL5: Event Handling

www.mql5.com

The MQL5 language provides handling of certain predefined events. The functions for handling these events should be defined in an MQL5 program: function name, return type, a set of parameters (if any) and their types should strictly correspond to the description of an event handling function. The client terminal event handler uses the return...

I'm not sure how that answers the question. Is there something I'm missing here?

I understand about the Tester events but what I want to know is how to detect 'Optimization'.
