How do institutions buy/sell large amounts of options?

Oh that's not a function of the executing broker, but rather that when the SHTF I watched prime brokers that you thought would be able to handle the heat and couldn't, when in fact, Lightspeed did. Amazing how those 5-sigma days separate wheat from chaff.


  • Very vague post.
  • Could you be more specific?
 
So those dealers or MM's are not available to take the other side of an order from a retail trader because they are more exclusive and not on an exchange I guess? Cuz when I send an option order for a 100 in IB, I see it gets split into ten thousand partial fills with some of the fills for like 5 contracts from the exchanges. And it takes forever for it to get filled. If the smallest contract size those MM's can fill is 100, my option order should've been filled with ONE fill.

So how do I get access to those MM's?

I get the same thing from IB. Send 100 and get 7 or 31 and then the market moves away and you have to chase it. This gets alleviated a little if I am less aggressive on the price, walk it down much faster and/or put it out there when the market is pretty calm. This is on ES FOP spreads.

One thing I found is that when the market moves away from you, all you have to do is remove the rest of the order that is not filled and then you will see your unfilled order was actually at the NBBO price and your order was the ONLY one at that price. And if you remove your order, the market will actually come back to the previous price and will even price improve. That happened to me many times. I used to chase all the time until one day I got so fed up I just removed my unfilled order and I discovered this.

I trade one of the most liquid instruments in the market with extremely high volume, there is no way that my mere 100-option order would move the market when option orders of 1K or 10K can get filled without a blip on the market. I dunno if that's IB's TWS being slow in updating the prices or if it's MM's playing games on exchanges.

I will be interested to hear what Mr. Morse says.

Not sure what to respond to. If you trader QQQ or SPY front three expiration and the options is not close to 100 delta, I have seen brokers selling that the offer is 25,000+ options to get an institution to take it as they can play without moving markets. Size has more effect with liquid stocks that are hard to hedge or when there are no customer orders in other strikes of the same symbol.

And, if you better wide markets where your bid or offer still provides an edge, you can expect an automated MM to match or better your order to play. They have no incentive to show their best without competition.

This is my original question:

I second or third support for Robert Morse. Very helpful, and pretty much everything he says makes sense. Plus I think he was the first person to respond to my first ET post (question). Top notch!
 
Even an order of 2 contracts on high volume option contracts such as GOOGL, AMZN, TSLA at the respective bid/ask can be split into 2 and filled one contract at a time seconds apart.

I have had that happen a few times through BMO Investorline. Perhaps by the time I hit enter the bid/ask as changed hence the splitting up the order.
 
You can't access market makers as a customer. You can only work an order looking for liquidity electronically.

You mentioned earlier that:

An institution would likely use their broker's trading desk or a third party trading desk like BTIG. Those desks have access to a small list of large MM, a larger list of smaller MM and a group of hedge funds that focus on providing liquidity. They communicate over the phone and through a messenger service like Pivot, to "shop" the order. As a small market maker, up to 2010, I used AIM to respond to institutional option orders. I was required to respond with a 2 sided market for any request with a size of at least 100 up or I would be ignored. Most orders that came across were between 1000 and 10,000 and many paired with stock.

I am just curious how do I get access to those "small list of large MM or a larger list of smaller MM...that focus on providing liquidity" that you mentioned above? Looks like they are not on the exchanges if my mere 100-contract option order has to be filled in ten thousand partial fills when I sent the order to the exchanges via IB when those 1K or 10K option orders from institutions can be filled with one complete fill.

When those institution orders get filled by those "small list of large MM or a larger list of smaller MM's", do those orders get reported to the exchanges or the regulatory bodies or do those orders just stay private completely and nobody knows about them? Another of my curiosity question.
