Thanks for testing! I can confirm the STEPWISE problem, but no MT4 problem. The MT4 bridge is new, so make sure to install the new version. Check also if automated trading is enabled on the MT4 terminal. The access violation error happens when it is not enabled or when a wrong version is installed. If you checked everything and the error still happens, please post again - I'll then would like to look into the Zorro and the MT4 logs.
