There are several traders with seats on the exchange doing such successfully for many years now. Thats' my point, they have special commission rates and they're automated...one is actually using an algorithm.
I know one of them is not risking 2 - 6 points because that ain't scalping.
Had you said ticks (not points)...that's scalping. Yet, I do understand that new traders (those in the past 5 years) think scalping involves points and not ticks if you didn't mean to say points. Seriously, you said 2:1 gain versus risk while risking 2 - 6 points. That's 4 - 12 points gain versus 2 - 6 points.
I have been with Emini ES futures
since its birth and I've never met anyone that scalps like that but I have met many with those same numbers via
ticks...a few of them profitable but they ain't manual scalpers. Thus, traders looking for points like that...they are just simple day traders...not scalpers.
