Vastly different prices for options?

Right now OptionsHouse is quoting WTW 5-5-17 23.5 call for 1.10/1.40 bid ask and tradingblock.com is quoting it for 0.15/0.30

What gives?

 

Yeah -- at the close, I got 10-bid-20.

Somet'in' be up wit' yore numberrrs.

 

Checked again, this morning. (I'm a curious nerd -- nothing new...)
The PUTS[!!!] were 70-bid-1.10-ask.
I suspect you had a put quote from OptionsHouse -- take that 1.10/1.40, subtract a day's theta-burn, and "Could be!"

Looks like good quote,Robert, but i really dont know that market; it can pay to focus on a few in addition to many. I was 99% sure i got a bad/bad/LOL quote on SPY, this month , on one of my charting services. IT was a bad[very wrong] quote.

And the lower the volume the more in-accurate the quote maybe; look @ some FSBO ,ask prices.LOL For Sale By Owner, Asking Price.One real estate appraiser said ''ask price tells you what it is NOT worth''

 

It is just the OPRA feed. Can't tell you what he was looking at.

Even though he was noting real estate bookish; applies to many things .LOL

 

Too many people and machines for this large a difference - the trade engines would have traded over linkage. It has to be a bad quote or a misunderstanding of some sort.
