tstpierre, I’m noticing the same problem. I can use the strategy tester on MT4 but it doesn’t work on MT5. I get a similar message. The test will run but I will get 0 executions. I even tried speaking with a broker but they were unable to figure out why the EA wasn’t working.
I’ve tried several MT5 brokers but none of them work. It would be nice to have this option because some companies only use MT5 and the MT5 strategy tester is faster.
I hope he can figure this out.
