I see a lot of rubbish and mis-information being posted and much of it is deliberate I suspect to aid their sponsors, I will try and correct them (yes , as a 400% winner on both Sb and futures, 19 years in the game I think I have a right).
1) A broker is never a SB / market maker, never at least when functioning, to confuse the two shows a backward lack of knowledge.
2) An SB is not some hi-tech, HFT firm which can electronically " transfer " quote requests they don't want to " liquidity providers ".
3)An SB firm does not know who you are when you ask for a price, it's all anonymous, so there is no book " A or B".
4) It all very simple , not need for any fantasy complexities, when you accept their quote, either they accept that as they should or the shanigans may then arise - delay responses, re quotes , you know the story.
5) Stop hunting is not depending on curve fitting, that's an amateur pov.
If the stop, by the SBs judgment is not at a pivot point then they will likely leave it alone. If it is then they may consider hunting it. They hundreds of opportunities a day they won't worry if they miss one or two hunting chances.
6) Stop hunting is NOT, repeat NOT illegal. The SB have the right to move their markets around, this is why they are called market makers !
Anyone who says it is , please tell me in my very clear example of #65, what is illegal in that in terms of SB action ?
