Why is my account like this

I started with £10 and would like to add more but I’m reluctant after it seems I can’t use my money

£9.02 is the amount you invested or used for holding a position ,£3.19 is the free fund you can invest or withdraw…you have to close position to use thta £9.02 but can get less OR MORE depending on your current P\L…

How do I close the position

You have to wait till the markets are open so that the order can be executed
