Firstly, check if trading is allowed by clicking Tools -> Options -> Experts tab -> Allow real trading. Ensure that the EA button on the main toolbar is pressed. On the top right-hand corner of your chart, you should be able to see a smiley face if the EA is activated correctly. If all is fine, but the EA is still not trading, check your log files via the Experts tab in the Terminal window (It should show what errors occur).
