I see, the behavior changed a little bit with the latest Zorro version (1.74.2). But it's still kind of weird.
When I run Z9 with the custom asset list (attached to the post above) I got:
Capital invested 5000$
Max drawdown -937$ 4.1% (MAE -3551$ 15.7%)
Max open margin 4064$
Capital required 4537$
Capital required is lower then capital invested. However, you pointed out it's normally 10% higher then value of Capital slider (5000).
Also, the first trade in the log is:
IAU 0.50 0 -> 1068
[IAU::L7801] Long 1068@5.85017 at 00:00:00
VGK 0.50 0 -> 133
[VGK::L7802] Long 133@46.71027 at 00:00:00
Vol $12460 Bonds $0 Margin 4984 Levg 2.5
Margin = 4984, however, performance report says that Max open margin = 4064$. So, the max margin is lower then margin of a first trade??
I wonder if it's a normal behavior? If yes, could you please explain these discrepancies.
