Hit the Bid
To hit the bid is to sell at the posted bid — you are the aggressor lifting liquidity on the sell side, not joining the offer.
Definition
Hit the Bid refers to you are the aggressor lifting liquidity on the sell side, not joining the offer. Keep that definition fixed when comparing series, managers, or regimes — renaming the same tape does not create a new signal.
Why it matters
It is a named object desks use to frame risk, positioning, or process. When you are the aggressor lifting liquidity on the sell side, not joining the offer shifts, related hedges, limits, and narratives usually need an explicit update rather than a quiet assumption.
Case
Suppose a desk is positioned for the opposite of what hit the bid is saying. If you are the aggressor lifting liquidity on the sell side, not joining the offer moves against that book, the first question is not “is the story clever?” but whether size, hedges, and stop logic still match the observation.
How to read it
Keep the definition fixed, then challenge it with cross-checks before sizing. Prefer a short written null hypothesis for Hit the Bid: what would falsify the current reading in the next window?
