It was NOT any problem with AMiBroker just
ridicolously high "max. open positions" setting set to 1000.
With 26 years of EOD data and 10000 symbols that means
10GB of RAM!
And of course he ran out of memory.
Once "max open positions" is reduced to some value
that actually makes sense (100 or less), there are no problems.
The most annoying fact is that this issue was resolved
via support channel weeks ago, yet AmiBroker is target of some unjustified bashing again.
