MT4 OrderSend Error 3

Post by elliot_123 »

I tested with open bar only data and it got from 2007-1-1 to 2015-3-5 and then said error mt4 and error 3 in journol. I could not figure out why. I did look on google. do you think it could be the data I exported from tickstory?

Hi Elliot,

I assume you're referring to "OrderSend Error 3" message? If so, this error is due to "ERR_INVALID_TRADE_PARAMETERS".
It means you have either:

1) Specified the incorrect parameters in your "Custom test settings" (eg. Set of a lot step of 0.5 but trying to send an order of lot size 0.1)
2) Specified the incorrect parameters in your EA (eg. Lot size is correctly 0.1 but you are trying to send an order with a lot-size of 0.05).

The best approach is to ensure you are only using your broker settings (i.e. NO custom settings). If you are still getting the error, it means there is a problem with your EA which you will need to trouble-shoot accordingly.

Thanks.
