There wont be any smiley on all ea's so not just this one.
For the not ordering this is probably an issue with the ea itself and not related to the smiley.
Did you install Microsoft Windows Fonts when you installed PlayOnMac?
Regarding the trading: Press F7 and check that "Allow live trading" is ticked in the Expert's Common tab.
This needs to be enabled in addition to the AutoTrading button.
If I look up the installation in Library/PlayonMac/wineprefix/Forextrader/drive_c/windows/Fonts - that dir is empty - so no fonts seem to be installed.
