MQL4: isTradeAllowed() always returns false

I'm using a demo account on Alpari and I can do manual trades just fine, and I've also enabled the option that allow EAs to trade. So I don't understand why isTradeAllowed() always returns false?

The only reason TradeAllowed() returns false is you have not enabled trading for the EA on that chart. Check the EA properties and look for the smiley face on the upper right hand corner of the chart.

I wonder if an expired demo account would do the same thing? (not that this is the problem though.)

You would not get any tick updates for an expired account.

It's fixed now, I had to remove and attach it again. Thanks
