As of May 28, 2026, ProAssurance Corporation (PRA) has 507 contracts traded today against 11.6K contracts outstanding. Open interest breaks down as 428 calls and 11.1K puts. Turnover ratio is 0.04: typical maintenance flow relative to existing positions. Gamma concentration is 0.84: open interest clusters at a few strikes, creating localized hedging pressure.

How PRA volume & open interest Data Feeds Strategy Selection
Strategy selection on ProAssurance Corporation options does not derive from any single metric in isolation. The volume & open interest view above sits inside a broader read: ATM IV currently sits at 42.7% and dealer gamma exposure is negative, so dealer hedging amplifies directional moves. Combine the volume & open interest 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 PRA volume and OI data
The two-panel chart above splits ProAssurance Corporation contract activity into volume (daily flow) and open interest (cumulative inventory) per strike. The per-strike grid table beneath gives the precise numbers for the densest 30 strikes. Current put/call ratio is 100.40, put-heavy - protective or bearish positioning dominates. Total call OI of 428 versus put OI of 11.1K gives a put/call OI ratio of 26.01 - structurally a slower-moving signal than the volume-based ratio.
PRA 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. The per-strike grid distinguishes the strikes attracting flow today from the strikes carrying accumulated inventory - high volume at strikes that also carry high OI typically means rolling activity (closing front-month, opening longer-dated), high volume at low-OI strikes typically means fresh directional positioning. Combined with the current negative dealer-gamma regime, large OI clusters tend to act as price repellents that accelerate moves through key strikes.
Using PRA 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 PRA sits at 21 days, so near-dated volume currently dominates the flow reading.

- What is the PRA options turnover ratio?
- As of May 28, 2026, PRA turnover ratio is 0.04 (507 contracts traded against 11.6K contracts outstanding). A turnover ratio below 0.5 is typical maintenance flow against existing positions.

- Why does volume-open-interest matter for PRA options?
- Volume tells you what is being traded today; open interest tells you what was already there. The combination separates opening flow (today's volume building new positions) from closing flow (today's volume unwinding existing ones), and locates the strikes that carry hedging-driven support or resistance based on dealer-gamma concentration.
