Default columns: ticker, current IV, IV rank, IV percentile, 52-week IV high/low, expected move (30 DTE), and earnings date. Sort by IV rank descending to find premium-selling candidates; sort ascending to find premium-buying candidates. Add custom columns for delta-30 strike, ATR percentage, or whatever metrics drive your strategy selection.
Update frequency is sub-minute during market hours. Set IV alerts to trigger when a watchlist ticker crosses an IV rank threshold — useful for catching IV expansion during volatility events or IV contraction after earnings. The watchlist is the workspace from which most active premium sellers run their daily process.
