Hello!.
I keep getting this message and in the mail it says :Failed Trade: Type: BuyMarket Symbol: EURJPY Units: 25000.
I check in the EA setting of EURJPY , the lot size is 0.25. I have max number of positions allowed:2 and sometimes there are 8 positions from the same EA.
Please let me know how to solve this problem.
Thanks

Check you use the same number of digit as your broker. (4 or 5)
If that does not help please post your strategy file and broker name, and account type. 1 lot for micro account is not the same as 1 lot for a normal account.

I tried but the problem persists. The lot size is 0.20 but there are too many incoming mails which said trade could not be completed due to insufficient funds: Failed Trade: Type: SellMarket Symbol: GBPJPY Units: 20000. It does not happen all the times. There are trades entered. I check the digits and it is correct. The broker is OANDA and attached is the file.
Thank you

If 0.20 is equivalent to 20000 units the ea is doing the right conversion. This message "Failed Trade: Type: SellMarket Symbol..." comes from the server so it means that the server tell the ea that cannot execute it due to lack of funds. This is odd since we check for available funds before sending the order. You may need to take a look at the logs when the error takes place. You can post them here or send it by email to support. OANDA has its own integration to mt4 so your order goes to mt4 but it is executed by fxtrade which is different from any other mt4 broker.

Not all trades give error just about 30% of the time maybe once or twice a day. When the trade is executed, the lot size is 0.20. If it happens, it crashed the MT4.
Thank

Again we need to see logs to find out why. The issue may be related to the way oanda connects mt4 to its server. Oanda does not use mt4 like other brokers.
