Optimizer with ZERO (0) value

Hello,


The MT4 Optimizer returns 0.

What could be the problem?

Of course, the robot works on a normal test.


More interesting:

At the same setting, the robot gives a normal value for EURUSD and 0 for the GBPJPY in the optimizer.


Thank you very much,

Szabolcs

Try to indicate the storing folder for optimiser.

.

tester > properties of expert > parameters >  register/store and store something into the .set folder

Sorry but I don't understand exactly what I should do. Can you write down more accurately?

Unfortunately, I still don't understand. Why should I change my backup folder or the name of the rescue? My problem is that the optimizer generates a zero (0) value for testing.
