In the next few days, I have to decide whether to switch to TT 7.x or keeping for other few weeks the old but reliable release 6.x. Also the broker informed me that the 6.x server will be disabled over time. Nearly one year after the 7.x release, it seems the 7.x is not so 'perfectly' reliable even if (maybe) faster, at least in some condition. However I don't know whether major steps forward have been reached in term of reliability with the latest fixes. Currently I do not need the X_Study and also I do not use the Pro version. - Anyone is willing to share his experience with this transition?
