Back when I started, the required capital for Z12 was higher than the initial capital. So when I started my account with a $5K deposit, I set the capital slider to about $4K.

After version 1.83, the Z12 backtests began showing a required capital number that was less than the initial capital. I'm not exactly sure how to interpret that, but I've since adjusted the capital upwards to be just a bit under the actual equity in the account.

I changed nothing in the ini file except the max capital setting.
