Why? If the HFT firm was willing to offer me $X 2 milliseconds ago they are probably still willing to offer $X now. It isn't like there has been time for anything to change; there are going to be short periods of time where there is literally no new information.

And they are just as likely to be offering me more now than less as conditions change.

if they weren't able to move their price 2 milliseconds later, they wouldn't offer $X in the first place.
