If you are getting Off-Quote you can increase the max deviation to reduce the likelihood of it appearing. If you receive the Off-Quote message, it means the market price is different from the price you requested in your order. You can enable max deviation and set it to 10 or 20, which indicates 1.0 or 2.0 pips. This gives you flexibility in case the price has moved when the order is submitted for execution.
See xgavinc's post 2 up for instructions on how to set a default max deviation for every order.
And finally, just a reminder that trading closes today at 21:55GMT and will open again on Sunday at 22:15 GMT.
Have a great weekend!
