I don't understand how it can get to -£20,000 when I started with £10,000, all my shares have gone up in value so £12,000 looks right to me, I didn't get the -£20,000 because I don't understand how a share can get to a negative value, I thought £0 would be the lowest possible. I don't understand how this thing works, I just thought I was buying normal shares.
It is a spread bet account.
