MT3 API problems...

 
Hello guys,

I am trying to send order thru API 3.72. But I get these weird messages. Can someone pls tell me what could be the problem and how can I overcome these problems.

Order failed [symbol is in instant execution mode but not selected]
Order failed [Old version]
Order failed [Unknown error]

I am trying to send orders with s/l and t/p. Moreover my S/l and T/P are 50 pips above current Mkt prices. Thanks in advance
