How BCYC put/call volume history Data Feeds Strategy Selection

Strategy selection on Bicycle Therapeutics plc options does not derive from any single metric in isolation. The put/call volume history view above sits inside a broader read: ATM IV currently sits at 131.9% and dealer gamma exposure is negative, so dealer hedging amplifies directional moves. Combine the put/call volume history data here with the volatility-skew surface, dealer-gamma exposure, max-pain level, and upcoming-events calendar to build a positioning thesis. Risk-defined structures (credit spreads, debit spreads, iron condors) are usually safer than naked positions while the regime is uncertain; the data on this page anchors the inputs but does not by itself constitute a trade thesis.

How to read the BCYC volume data

The volume time-series above tracks Bicycle Therapeutics plc options trading activity day by day. Volume is a flow measure - contracts traded per day across all strikes and expirations - so spikes flag activity, not positioning. Current put/call ratio is 0.82, roughly balanced. Total call OI of 5.0K versus put OI of 6.9K gives a put/call OI ratio of 1.36 - structurally a slower-moving signal than the volume-based ratio.

BCYC flow vs positioning

Volume tells you what flows happened today; OI tells you what positions accumulated. Both can move in opposite directions: rising volume with falling OI means contracts are being closed (covering); rising volume with rising OI means new positions are being opened. The combination matters more than either alone for reading sentiment. Combined with the current negative dealer-gamma regime, large OI clusters tend to act as price repellents that accelerate moves through key strikes.

Using BCYC OI/volume data alongside other surfaces

Per-strike OI is the input to dealer-gamma calculations: strikes with elevated call OI generate gamma walls that dealers must hedge into as spot approaches them. The gamma-exposure page combines this distribution with the dealers' assumed-long-gamma assumption to project hedge flow. Volume cross-checks recent positioning shifts in the chain that haven't yet shown up in cumulative OI. Pair both with the term-structure view on the volatility page to determine whether the activity is concentrated in near-dated event hedging or longer-dated structural positioning. Front-month expiration for BCYC sits at 28 days, so near-dated volume currently dominates the flow reading.

How much BCYC options volume traded today?

As of Sep 18, 2026, Bicycle Therapeutics plc (BCYC) traded 193 total options contracts, split as 106 calls and 87 puts. Volume measures today's flow only; standing inventory is captured by open interest, which reconciles after the close.

What is the BCYC put/call volume ratio?

As of Sep 18, 2026, the put/call volume ratio is 0.82. Equity-only PCR has three competing interpretations - sentiment-contrarian (extremes signal turning points), hedging-flow (high PCR can be portfolio insurance demand rather than bearish bets), and informed-flow (the volume signal carries short-horizon predictive content per Pan and Poteshman 2006). Resolving which frame applies requires context on whether the flow is opening or closing and which strikes carry the activity.

Is BCYC options volume elevated?

Elevated flow relative to the BCYC recent average is one of the strongest signals of institutional positioning, pending news, earnings expectations, or hedging activity. The most informative reads combine elevated volume with directional structure (single-leg or vertical), aggressive execution (at the ask or sweep), and an upcoming catalyst on the calendar.
