Why does volume-open-interest matter for NSPR 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.

How NSPR volume & open interest Data Feeds Strategy Selection

Strategy selection on InspireMD, Inc. 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 21.8% and dealer gamma exposure is positive, so dealer hedging is mechanically mean-reverting. 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 NSPR volume and OI data

The two-panel chart above splits InspireMD, Inc. 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 0.00, call-heavy - speculative or bullish positioning dominates. Total call OI of 469 versus put OI of 0 gives a put/call OI ratio of 0.00 - structurally a slower-moving signal than the volume-based ratio.

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

Using NSPR 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 NSPR sits at 20 days, so near-dated volume currently dominates the flow reading.
