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.

Path parameters
symbolstring required
Example:SPY__250516C00580000
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.)
