Here's one I'll try today. Won't be the first time that I have made a fool of myself.
1-Stop betting as soon as you make a profit of say 10% at least. That is up to you as to what % you reckon is a fair thing.
2- use fixed odds . Win or place that is up to you.
3-Most importantly is to stop after two losing bets. Don't ever chase money you have lost.
4--Like all systems it still comes down to what you pick. Today I went to the Herald Sun site and took four shorties .Paper prices
Therefore we will see what fixed odds that they put up for M 1/5.
I'm aiming for 10% profit or more but will only bet $1 = 1 Unit.
