MetaTrader 5 Enters Beta Testing

On September 9th, which they refer to as a "Red-Letter Day", MetaQuotes announced on the MQL forum that the arrival of the long awaited MetaTrader 5 has just got one step closer. They have now started "closed beta-testing of the MetaTrader 5 terminal":

The new client terminal has been sent to some members of the MQL4.community for testing. They will help us find errors that unfortunately always accompany the developments of new products. Being created from scratch, MetaTrader 5 is not an exception.

They also promise that "the closed testing will be followed by the public beta-testing; and all persons interested can participate in it. Follow the news!". We will certainly be eagerly awaiting any further news on the progress of MetaTrader 5 here at the Trading Gurus!

Of particular interest to us is how compatible the new client terminal will be with existing expert advisors written using the MQL4 language. This question should also be taxing the brains of all the MetaTrader 4 "robot" vendors out there too. Since MetaTrader 5 is "created from scratch" and includes new object oriented programming features they might all have a lot of work to do to get their creations working on the new platform by the time it ultimately arrives on all our desktops.
