Three richness signals — used together they tell you whether the market is paying you to sell vol that isn't being realized.

• · IV Δ% — current ATM IV vs the symbol's recent 30-day baseline. ≥+30% = SPIKE (sudden jump).
• · IV Rank — where current IV sits in its 1-year (min, max) range. ≥60 = expensive in its own history.
• · IV/HV — current IV divided by 30-day realized vol. ≥1.2 = options pricing more vol than the stock is actually moving. This is the real edge — high IV alone just means a volatile name; high IV above HV means the market is overpaying.

The green EDGE badge fires when IV Rank ≥ 60 AND IV/HV ≥ 1.2 — that's the combined "sell-premium-now" signal. Blue BIG MOVE = |today Δ| ≥ 3%.
