expert testing in MT5 with demo account

 

is it possible to test an EA while on Demo account?

when the EA sends an order. I receive always the annoyiong runtime error:

4756

Trade request sending failed

The advisor compiles without errors....

 

Same here...After MT5 "live update" to version 5.00 build 540.

With the previous build all trade requests were executed with no error but unfortunately, with the current version (build 540) all orders fail with run-time error 4756. Obviously I am using /testing the very same EA...

I really do not what to do...any suggestion/help would be appreciated.

Cheers
