PARAMETERS+RULES(PATTERN+FUZZY) WFO = OOM - 05/12/15 06:01

A Strategy using RULES+PARAMETERS &
adviseLong(PATTERN+FUZZY) with 8 inputs &
NumOptCycles = 2;
NumWFOCycles = 7;
over merely 1 year of H1 bars

It consistently crashes 44 minutes into Train, on Walk[5]O[1] P[1], for "out of memory". Is this expected?

Code:

Profitable patterns: 204.
Parameter 1 step  1:  100.00 => 2.66  56/39

Generating EURUSD_S rules...

Running out of memory is always expected when you program something. In strategy scripts, the two most frequent reasons for running out of memory are too many trades, and too many price ticks.

Thanks.
These are soft limits, and Zorro is not aware when it approaches or exceeds them?
