How APLS put/call volume history Data Feeds Strategy Selection

Strategy selection on Apellis Pharmaceuticals, Inc. 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 25.3% and dealer gamma exposure is positive, so dealer hedging is mechanically mean-reverting. 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 APLS volume data

The volume time-series above tracks Apellis Pharmaceuticals, Inc. 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. Total call OI of 14.1K versus put OI of 13.7K gives a put/call OI ratio of 0.97 - structurally a slower-moving signal than the volume-based ratio.

APLS 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 positive dealer-gamma regime, large OI clusters tend to act as price magnets through expiration cycles.

Using APLS 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 APLS sits at 27 days, so near-dated volume currently dominates the flow reading.
