How do we go about getting 5.2? I'm currently running 5.1.
Also, is there a way to "restore" from its previous state after being closed? Would be awesome if every time I opened the program it'd bring up full trade history for markets.
5.2 is still at beta stage, it will be released around the middle of January.
And yes, there is a way to restore all open markets, settings and orders.
You don't get to restore trading history though. This is stored at separate logs.
Check
File => Save and
File => Load for each exchange.
