MT4 Expert Advisors EA error 133 trade is disabled

Sometimes your EA runs well without any issue on demo account, but it will give error such as code 133 "trade is disabled" when using it in realtime account.

This usually can happen when your broker has more than one symbol for the same currency pair, for example EURUSD and then the same pair with some suffix at the end like EURUSD_Ask.

Another reason for such error can be when trading on some or all pairs is disabled by your broker. Trading might be disabled temporarily or permanently. Maybe it’s your new account and your broker needs to enable auto trading option on their side. You should contact your broker about this.
