Trade by symbol is disabled by the trading server

[PhotonAD]

Hi team

I have this message when I try to place a trade with MT4 Trade Assistant: "Trade by symbol is disabled by the trading server"

I still can place a trade for the same Symbol manually... Never had this problem before with the trade assistant. 

How can I fix this?

thanks

I had the same issue once. Just contacted my broker and they solved the issue - probably some brokers put some kind of limitation when it comes to trading with expert advisors.
