On Monday, MetaQuotes released the new MT4 build 600, which have already been rolled out by a number of brokers. The update introduces a number of changes, which are already causing issues for virtually everyone developing software for MT4. The video below goes through the changes and the issues. We highly recommend that you watch it.
We are currently working on updating all our products to reflect the changes in the new version of MT4. Our first priority is FX Synergy, and we expect the update to be released no later than Friday this week.
