Redman you raised good points. In 1997-99 I sat next to a guy in Atlanta flipping $2 stocks making 1/8, then 1/16. At that time there were no ECN rebates and he was prob paying 1.5 cents/ During the 1/8's if he makes min tick move he makes $95 on a 1000 lot, when 1/16 he made $47.5. Now, if he scalps the min ticks and assuming hemakes both side of rebate , at .0025per sh his net pnl is $9.Obviously he can hold out for more than 1 penny albeit at a little bit more risk. Maybe the trick is to find stocks that moves a tad more than LU in order to get that 2-4 penny profit. Flipping these stocks for 2-4 cents is what you mean by high vol scalping correct?
