Definitions — how to read this
Premium $ — mid price × today's volume × 100 = the money actually traded in an option today (not just contract count).
Net (call − put) — share of premium going to calls vs puts. Calls bid (positive) = bullish flow; puts bid (negative) = bearish / hedging.
Cohorts — short-dated (0–5d) = retail / speculative (the 0DTE lottery); longer-dated (21d+) = institutional (hedging / positioning).
Divergence — retail bullish while institutions defensive (or vice-versa) is a classic late-move / reversal tell.
Caveat — extreme short-dated call buying can be contrarian froth; Phase-3 calibration decides momentum vs contrarian per horizon.
