How to read it

  • Each expiration has three rows: calls, puts, and the two together. The last block, ALL, is every expiration shown.
  • VolmBuy and VolmSell are the contracts traded today where the buyer or the seller was the aggressor. VolmBS is buys minus sells.
  • OI is open interest.
  • GxOI, DxOI, VxOI, TxOI, VannaxOI, VommaxOI and CharmxOI are a greek multiplied by open interest (gamma, delta, vega, theta, vanna, vomma, charm), added up over the strikes.
  • In the greek columns the puts are subtracted: the puts row shows them with the opposite sign, and the third row is calls minus puts. Volume and open interest are plain sums.
  • stks: the same kind of sum by strike.
  • joy: one parameter at every strike and expiration.
  • flow: the totals of every stock, ranked.
