Hello
Could you change max combinations amount? I can run strategy for days, but I expect more combinations in one test. (now it's 1000)
Cheers, Hoshi.

The more combinations, the more Max heap size should be set or you will get OutOfMemoryError. We have set a limit of 1000 to avoid it.

Please do some extra option in advance settings, because it's very important for people who test multiple options in strategy. (I have heap size on much higher level - using this computer only to test) Please be kind and add some settings for advanced users. (+ if it's possible add some note what max heap is needed to X combinations - but not necessary) Often i get's 1000+ combinations, sometimes little more than 1000 and I am unable to do test. (for example 1024...) Cheers, Hoshi

+ please repair problem with historical tester (when you check in optimization mode and for example you want to check 1000 combinations there is some problem with tester - when you pick (next example) 250 combinations in one check then program should run 4 times 4x250=1000, problem is that after 2 round, at start of 3 (from 500) program refuse to start and calling "preparing on start" and then program window turns black if you would like to click somewhere on screen) It's very annoying because I am unable to check all parametrs (tester stops) and after that i can't start from part where it ended.

Is there a way to change that number with a Java Property or an argument. At least for advanced Java API programmer I would love to use the current fonctionalitiy in JForex rather than having to write a lot of different ITester client. Can this be considered?
