How SDP open interest history Data Feeds Strategy Selection

Strategy selection on ProShares - UltraShort Utilities options does not derive from any single metric in isolation. The open interest history view above sits inside a broader read: ATM IV currently sits at 48.1% and dealer gamma exposure is negative, so dealer hedging amplifies directional moves. Combine the open interest 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 SDP open-interest data

The open-interest time-series above tracks the total ProShares - UltraShort Utilities options inventory outstanding day by day. OI is a stock measure - the cumulative position count - so trends flag accumulating or distributing positioning.

SDP 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 SDP 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 SDP sits at 17 days, so near-dated volume currently dominates the flow reading.
