Exactly! And it’s also significant to the market maker. And the market maker is likely saying “hey, why should I give that guy (you) the extra nickel, dime, or quarter on something that ends in a few hours?” Instead they create wider spreads to discourage the act of rolling to capture that nickel, dime, or quarter.
It’s also important for us to remember that it’s not JUST the market makers that create the spreads. As far as I am aware, best bids and best asks MUST be displayed on exchanges (in a timely manner). If there are people out there, aside from the market makers, that are willing to put a certain bid or a certain ask, and if those spreads are tight, then they will be displayed as tight. And if they are wide, they will be displayed as wide. But just as this is true, the market makers have a much larger effect on bids and asks because many times they are the only bid or ask.
When I sell options, I place an order at my desired price. But I periodically look to see how they are trading, and I’ll look at the level 2 book bids and asks, and sometimes I’ll decide to move my ask by a nickel or a dime. It all depends.
Just as an example, looking at an option I sold a while back, the Berkshire Jan '27 400s. Right now the bid/ask is VERY wide at 9.25/9.75, and the book is very deep at those numbers. It only traded 3 contracts today and nothing is moving. If I wanted to sell some more (I don’t right now), I would have to move the ask down, first to 9.70, but I bet that wouldn’t get any takers. I’d probably have to step all the way down to 9.45 … I’m tempted to do the trade for fun just to check my instincts, LOL (but I won’t because I’d want $15 or so for that options … anchoring is a real thing). As I type this, the bid went up to 9.30, and now 9.40. The book isn’t that deep, but these kinds of long term options (especially on Berkshire) usually aren’t.
I don’t mind the bids and asks meandering, and I don’t even necessarily mind wide spreads when warranted. What I don’t like is “knowing” that I probably could get an execution my lowering my ask by 2 cents, but being forced to lower it by 5 cents.
[EDIT: Now the spread on that option is 9.35/9.90, still very wide. No new trades of course.]
