I'm obviously doing something very wrong in my pair selection, I have decided to halt my current trading as I am now down 18%, having had 7 of my last 8 trades lose!! I seem to be very good at picking trades where a fundamental price ratio change has happened and no revertion. As a result I am also not getting enough trades as these bad trades are using my margin up for 7 days or so until I close them.
I think my key problem is I don't know my stocks well enough, like SKC who I notice is very knowledgeable based on his posts. I'm just not in a position to get to know every Stock in the FTSE350 that well...maybe time will help...
Anyway, i'm going to have a rethink of my strategy and paper trade for a bit.
Thanks everyone for your help, especially SKC. Good luck everyone with your trading...
