All,

I am going to run the results for as long as it takes to either proves this works or doesn't work.

Todays selections where Res of 1 means a win and Res of 0 means a loss.

Rather than taking a double bank method which i tested against I think this is good enough to work on a day by day basis and that makes it easier for me to post so based on that I will do the following:

For progressive:
If in profit at end of day : Take profit and start a new bank
If showing loss at end of day : Continue using same bank for tommorrow or till bank busts.

For level stakes : Start new bank every day as it doesn't matter.

WOW look a losing level stakes system is in profit ... OH MY ...

The reason backing and laying are both in the negative for level stakes is because the 5% commision has already been taken into account on all winning bets.

Oh and max bet is 10% of starting bank (or $100).

Good Luck.
