The ‘Max Next stake’ (top area) is calculated by the percentage of the ‘Account Funds’ or Balance of your Betfair Wallet.
E.g. If % bank is set to 1% and the funds available are £500 then the stake will be calculated as follows:-
Stake = 1% x Account Funds = 1% x £500 = £5
The % stake setting can be between 0.01 and 100 and is available for backing or laying.
You can also choose to only adjust the stake upwards as the bank increases. If the bank reduces the stake will not be reduced. Here we are using the Virtual Wallet to specify the stake use the £500 Virtual Wallet amount
