Need help urgently. I have this problem and unable to solve it. I've tried restarting my computer and reinstalling the MT4, but none works. I can't see and load any chart, and unable to switch periodicity.
This is showing in my journal:
2012.04.24 07:24:51 HistoryCenter: unknown chart 'EURUSD1440' in history synchronization
2012.04.24 07:24:48 HistoryCenter: unknown chart 'EURUSD240' in history synchronization
2012.04.24 07:24:45 HistoryCenter: unknown chart 'EURUSD60' in history synchronization
And the same thing for all other currencies. Look at the screenshot:
1st - First make sure your mt4 has internet connection and is authenticated
2nd - Close those chart windows and right click on "Symbols" and right click on the market watch window and click in "show all"
You should see a list of symbols.
From Navigator windows I think you using MetaTrader from tradeorbitz.
