I think that single stock futures SSF will debut this spring but I would like to know how it will impact trading especially on shorting or with bullets. It seems that all the negative aspects of shorting (up tick rule) will be eliminated, the cost will be lower than options, and that leverage will increase significantly. Since I am new at trading, I do not know if you will be able to trade SSFs on ECNs or through MM/SOES. How will this impact the way intraday trading is done? Moreover, would you have to get an additional license to trade futures professionally?
