Quote from dcunited:
I think the poster is using this strategy to capture quick, minor pullbacks. As long as you covered within the next 4 or 5 prints after the big gap print, I think one could be profitable. (they'd get crushed here and there but overall I could see someone making that work)
Assuming the specialist "spreads up" 15 cents (like for the thread example) we're looking at a 14/13 cents profit (max., if the spread goes back to 1 cent, minus commissions) vs. the risk of another spread in the same direction, say 5 cents loss on average (plus commissions, but it could be easily more than 5 cents). I've seen the trend continuing in the same direction of the specialist spread too many times, even after a relative big print (was the case today in SLB).
I'm not saying this isn't a viable strategy, just evaluating the overall risk and meaning that there are other variables to consider before jumping in (open book hedge, previous prints, state of momentum, specialist "habits").
