SAMPLE / ILLUSTRATIVE DATA - layout and logic shown; Live options-chain (Greeks/OI) data requires a paid feed (not connected). Do not trade on these figures.
Strike-by-strike volume across your universe. Sorted by premium ($ flowing in).
SWEEP = multi-exchange aggressive fill (someone in a hurry).
BLOCK = single fill ≥ 1,000 contracts (institutional size).
UNUSUAL = volume/OI ≥ 3x.
Premium-leader rows show where the largest dollar-flow is concentrating.
