Good points, and I will get to implementing those features, but I don't think they're necessary before I allow >1% risk.  If you don't want to risk >1% of your investment without the monitoring tools, do nothing and you'll stay at 1% risk.

It's possible for the house to have long losing runs, especially when most players make tiny bets.  The few who make the big bets pretty much affect the house's profitability.  In a long enough period I would expect the house to profit.  Wouldn't you?
