How O open interest history Data Feeds Strategy Selection
Strategy selection on Realty Income Corporation 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 18.3% and dealer gamma exposure is positive, so dealer hedging is mechanically mean-reverting. 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.
