First, check if trading is allowed by going to Tools -> Options -> Experts tab -> Allow automated trading. Then make sure that the expert advisor button on the main toolbar is selected. You should be able to see a smiley face in the top right-hand corner of your chart which shows that you have activated your EA correctly. If everything is alright, but the EA still does not work, check your log files via the Experts tab in the Terminal window (you should be able to see what error occurs).
