wondering if I'm blind or is this trade too good to be true. TZA @13.60 current price Nov 28 13.50 CALL 1.15 Nov 28 13.50 PUT 0.4 This looks like an arbitrage risk free profit...or is bigcharts glitched out? http://postimg.org/image/8uca61pt5/ image URL
Are those last sales or where you can do that trade by taking the offers in the put/stock and sell the bid on the call? This is not the best source for NBBO markets. Plus, you left out the column headers.
from what i know they are last sales. right side is puts and left side is calls. far lefts column on respective sides are last sale. last 2-3 columns on right of respective sides are bid ask
It's not a trade you can put on with the spreads in place. You should not look at last sale. You have to look at the current market. Last sale could have been 1 second or 1 day earlier. With electronic trading and hundreds of remote option MM, you will never be able to enter a risk-less spread without execution risk. Not even worth looking for trades like that. 1245
