I see, now it makes sense!

As to the Hredot point, about reinvesting...
With the default asset list test starts with Balance=5000. Margin is approx. the same, according to the log (=4989).
However, at the end of backtest balance = 15142 but the Margin = 7041.

I took this numbers from the log. I assumed, that with reinvesting according to pow(..., 0.9) formula, the margin will grow much faster and will be close to 15000 at the end of backtest.

I believe that's why Hredot mentioned that it's still needed to move Capital slider during live trading.

Jcl, could you please explain why margin grows so slowly while most of the profits are reinvested?
