Re LUK 1/15 puts:
They do show up in Think or Swim (TDAmeritrade), but are "non-standard"
09:22 me: get a msg when I try to trade these that they are "nonstandard"?
09:22 me: .LUK2150117C25
09:25 p.espinosa: hi. the reason they are non standard is that upon exercise, the LUK Jan15 options would deliver 81 shares of LUK instead of the standard 100. non standard adjusted options such as LUK Jan15's can run into liquidity issues, as traders normally just trade the standard option contracts
09:28 p.espinosa: the non standard split adjusted options need to be priced off of this: LUK stock price x .81
