How QSI open interest history Data Feeds Strategy Selection

Strategy selection on Quantum-Si incorporated 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 93.0% 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.
