# Chain-level call/put-aware bull/bear pressure

`GET /v1/chain-bull-bear/{ticker}`

Folds option type into the bid/ask/mid signal: a call lifted at the
ask is bullish, a put hit at the bid is also bullish (put selling),
etc. Returns overall bull/bear/neutral percentages plus call-only
and put-only bull breakdowns so callers can tell whether the
directional pressure originates from call buying, put selling, or
both.
