Yes version 4.2, the time frame is correct according to the manual in the course. I suggest you check your coding again, I have tried compiling several times in the MT5 metaeditor, but the results are the same. There are no open orders for the USDJPY pair on MT5 because of the error message on the MT5 terminal. Have you tried installing EA on the MT5 terminal? In the mq4 version the USDJPY pair is no problem.
