Per-contract call/put-aware bull/bear pressure
Single-contract counterpart to /v1/chain-bull-bear/{ticker}.
Maps a contract’s trades to bull/bear/neutral buckets using both
side (bid/ask/mid) and option type, so a bullish put-seller and a
bullish call-buyer both register as bullish pressure.
Authorizations
Skylit API key in the Authorization header
(Authorization: Bearer fs_live_<key>). X-API-Key is also accepted.
Path Parameters
OPRA option symbol in URL-safe form:
{ticker}__{YYMMDD}{C|P}{strike×1000, 8 digits} — the ticker and the
15-character contract block are joined by a double underscore
(__). For example, an AAPL $250 call expiring 2026-01-17 is
AAPL__260117C00250000. (A space-padded 21-char OCC form such as
AAPL 260117C00250000 is also accepted on some endpoints, but the
__ form is canonical and works across all contract routes.)
"SPY__250516C00580000"
Query Parameters
