In some quarters it is widely accepted that fixed profit betting is better value than level stakes betting. Again this is a matter of personal opinion. With level stakes betting, you are keeping your accounting on the ‘spend’ side of your book ‘fixed’ by sticking to one bet size to suit all. The upside here is that you can control your expenditure and can easily analyse your bank. The down side on the other hand, is that you are limiting the ‘income’ side of your book in direct proportion to the odds available on the bet ie, a 2/1 (3.00) shot will return far less than say a 7/2 (4.50) shot using the same stake amount.
In TSM there are several options. The Fixed Staking Plan allows you to set a target relative to your start bank. It also allows for this to change relative to your cumulative start bank by way of telling TSM when the last bet of the day is by using the last bet filter. See help manual for details.
