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?

Because the current beta version, as I just learned, only partially reinvested profit in the backtest. The mechanism was accidentally switched to a different formula. The next update will have the full reinvesting activated.

Thank you for the update!
I (and Hredot too, as he wrote above) would appreciate if the % of profit reinvestment could be controlled with a parameter. It would make the system more flexible.

How do we change the Start Date with the asset list?

By using assets that existed back then.
