Help please with "removing liability"

[goldfinch77]

I know this is basic stuff but I really don't understand it at the moment.

This is using automation, If I place a back bet at £10 on lets say O2.5 market at 2.8 and a close trade on selection when goal scored ( without ticking greening) if a goal is scored, as I understand it BA will close the bet, remove liability and leave a free bet. if the final result is then over 2.5 goals What will the profit be ?

I have been testing some of the strats using the above ( back Over 2.5 with the drip for example) Just cannot work out what the profit is.

Help.
