In communicating with scalpers and reading posts on ET, it is apparent that one of the main gripes is that decimalization has narrowed the spreads to the extent that traders who used to scalp teenies are now scalping for pennies. I'm thus wondering why scalpers aren't trading the e-minis, where the S&P e-mini has tick values of $12.50 per contract = 1/8th increment, and the Nasdaq e-mini has tick values of $10 per contract = 1/10th. I thought those wider spreads, combined with extreme liquidity, relatively low commissions (IB charges $4.80 roundtrip), low data feed costs compared to stock data feeds, the absence of market makers or specialists, and data feeds are available in Level II form, would make it highly desirable by scalpers. I want to get back into trading and am looking at all the options out there, and in researching the e-minis I couldn't help but pose this question. I may be mistaken in the above assumptions; please correct me if I am! Comments greatly appreciated.
