So, I start with a £600 betting bank (for example) which I divide into 3 smaller sub-accounts of £200 each. I leave 2 of the sub-accounts aside and start betting with only one of those sub-accounts. I bet with those £200 until I reach £400 (double my sub-account) if I manage to reach £400 I move £200 into the other 2 sub-accounts creating 2 side-sub-accounts of £300 each (matching my initial bank) and I continue betting with the rest of the money (£200) which I had left in the 3rd sub-account.
If I happen to lose the initial £200 from the first sub account I split the remaining £400 into 3 sub-acounts of around £130 each and only start betting with one of them until I reach £400 again and so on.
I only bet on 2 or 3 (max. 4) games per slip with average odds of 2.30 and stake 1/6 of my sub-account (if I have £200 I stake around £30 per slip)
Most importantly you should NEVER neglect the rules above and I guarantee you that after one month of using this money management strategy your balance will be a lot higher.
