Why MT4 do not autotrade?

Hi all. I made an advisor. On test it works fine. But when I put it in a system it not autotrade. And when I tested advisor on latest data it doesn't pick it up. Help please. (I use MIG Demo).

If the indicator is trading there is a smiling face in the upper right corner of your chart.

If it's not smiling, check that the Expert Advisor button in the toolbar is clicked green (not red).

Also in the Common Tab of your EA, when you add it, make sure "Allow Live Trading" is checked.
