EDIT$-two accounts....short term.Futures..mainly SPX...on IG Index...(UK broker-CFDs or spread betting-highly leveraged)..you basically enter how many dollars per point you would like to risk...and they credit or debit your account with the difference when you close the trade...(or when they close it for you lol lol-(feed very close to cash prices)- Have been trading the cash market less and less using my Etrade account..(mostly ATM or ITM options and leveraged ETFs)....but this is for longer term moves..
I also trade FTSE, OIL futures, and DAX...been playing with high grade copper for a couple of months....shifts...but OUCH...lol
