Hi guys,
I'm new to options trading and I'm curious about what these numbers mean. I'm looking at the puts for AVY.
I'm looking to sell a put for AVY.
For the 190 strike: the open interest = 7, volume= 1, bid size= 120, bid = 0.25, ask = 2.50, ask size = 147.
Is the bid size large enough? Do I look at the bid price or ask price when selling?
Thanks
Avery Dennison (AVY) is a *VERY* thinly traded symbol with little volume or open interest. Many strike prices have zero Vol or OI. The Bid/Ask spreads are wide because of that. If you're new to options you need to pick symbols that are much more liquid with much narrower Bid/Ask spreads. E.g. SPY options usually have a Bid/Ask only a penny (.01) apart. Ditto the QQQ.
Right now the July 21 Avery 190 Puts have a Bid of .25 (what someone is willing to pay to buy the option) and Ask of 2.15 (what someone wants to sell the option for.) Right now the 190 Put has a Vol of 0 (zero) and an OI of 7. That means that so far today no one has traded the 190 Puts and only 7 contracts are in play since the contract began trading. The Bid Size is 29 and the Ask size is 30 but consider the Volume which is 0. No bidder want to pay the ask and no one who is selling wants to accept the (low) bid.
I advise you to move on to symbols that are much more liquid. Either ETFs or individual symbols.
That said, it sounds like you need to educate yourself on options and how they work. Here's a list of my resources that's in my library. Start with a book or two and visit the web sites I have listed. You'll find a lot of valuable information that will help learn about options in general and the Bid/Ask Spread, Volume and Open Interest in particular.
As an aside, I trade futures options (/ES exclusively) which is has little higher learning curve that equity options (derivatives of derivatives.) I don't recommend that you start with futures options but have included one recent book (Garner's) in case you want to read more about the subject.
