Tickstory v1.7.3 has just been released.  In this version we have notably included support for the latest MT4 Build 920.  The changes include:
• [artf297155] MT Export: Now exports actual server name instead of info from MT4 settings.
• [artf297156] MT Launcher: Now supports Build 920+.
• [artf297001] MT4 Export: Fixed zero-divide error sometimes occurring in TickstoryExpertEA.
Please note that as a result of a breaking change in MT4 Build 920, you will need to regenerate your MT4 exports.
