Quote from learner2007:
I'm sorry, Martinghoul, I should have been clearer.
HFT is just getting started in stocks here, and lacking first hand experience we only know what we've heard here and there. His concern is if HFT is being done in these contracts to the extent that it makes execution quite difficult when placing orders at Best Bid/Ask 1 to 3. He is not a scalper, and is not placing very large orders. So maybe HFT shouldn't even be a point of concern for him?
Hope this is clearer, and thank you for your help.
