How SEA iv/hv history Data Feeds Strategy Selection

Strategy selection on U.S. Global Sea to Sky Cargo ETF options does not derive from any single metric in isolation. The iv/hv history view above sits inside a broader read: ATM IV currently sits at 43.7% and dealer gamma exposure is negative, so dealer hedging amplifies directional moves.
