That would be sad but funny, trying to trade one way futures. Is it even remotely feasible? Hit the 1st strong indicator, regardless of system, and it would simply blow up and drive everyone away.
Futures and derivative products were created to hedge against risk. No way they would ban short selling futures. That would mean banning the whole purpose of having futures. IMPOSSIBLE.
No. Index futures are regulated by CFTC, not SEC. Thank God !! Look at the bright side. It'll provide a great incentive to learn option theory: Buy Put and Sell Call.
