Monitoring PFIX open interest helps you see where real money is positioned on Simplify Interest Rate Hedge ETF's options and which strikes are attracting the most commitment from traders. Simplify Interest Rate Hedge ETF's open interest reflects the total number of outstanding contracts that have not been closed or exercised, making it a powerful gauge of liquidity, conviction, and potential support and resistance zones. Use our scanner to monitor PFIX options open interest in real time and find the strikes that matter.
Open interest is distinct from volume: volume counts how many contracts are traded in a session, while open interest counts how many remain open at the end of the day. Rising PFIX options open interest alongside rising volume suggests new positions are being built, while falling open interest signals positions are being closed. Heavy open interest at specific strikes often acts as a magnet near expiration and can hint at where dealers and large traders expect Simplify Interest Rate Hedge ETF to settle.
The Simplify Interest Rate Hedge ETF (PFIX) seeks to hedge interest rate movements arising from rising long-term interest rates and to benefit from market stress when fixed income volatility increases. The fund holds a large position in over-the-counter (OTC) interest rate options intended to provide a direct and transparent convex exposure to large upward moves in interest rates and interest rate volatility. Using OTC derivatives, usually only available to institutional investors, PFIX is designed to be functionally similar to owning a position in long-dated put options on 20-year US Treasury bonds.
Since the option position is held for an extended period, the ETF provides a simple and transparent interest rate hedge.
Pin risk into expiration, dealer positioning, liquidity checks for large orders — all of it starts with knowing where PFIX open interest is concentrated. Our scanner maps Simplify Interest Rate Hedge ETF's open interest across every strike and expiry, flags unusual buildups, and lets you drill into the contracts that institutional money is actually holding. Trade Simplify Interest Rate Hedge ETF's options open interest as the signal it is, not as an afterthought.
