Agree with every word phil......
Started off my spread betting day trading the indices......kept pressing buy when I meant sell and vice verse...nearly had heart attack watching the graphics reverse direction every time I jumped in...
I had a call from Capital Spreads offering me free technical analysis and he was telling me I was in their top frequent traders group...I then knew it was time to stop!
Only very rarely trade an index now and to be honest I only do that for a bit of fun with low stakes.
