Unable to trade, no "new order" button

 
I just recently change from an android phone to iphone 6, in my new phone i can't seem to make a new order on Metatrader 4, there is a Trade button on the chart view on the top right side but when i click on it nothing happens. when i click on the chart the only options it give me is Indicators,Object, Settings, and Cancel. I have tried to use a demo account and was able to make a new order.never had this issue on my old phone. and yes I have already re-install the app....please help
 

which broker?

 some brokers got broke (: last week. For instance, Alpari UK has stopped working and are waiting to be bought by FXCM - this week there's no trading in ALPARI. 

 
FXunited, my friends who are using the same broker can trade with no issues...
