SPY Options Position Size

[HtownTrader]

Hello,

I'm looking to get into options trading, and I have a question more about understanding the market and position size/liquidity than trading strategy:

How big a position size (dollar amount) could someone take in SPY and it be normal (not market-moving or anything like that)? In the hundreds of thousands? In the millions? Tens of millions? More?

And how quickly and in what dollar amount could that position size be quickly bought or sold while still getting a good price/minimum spread?

Thanks.

How much have you in the brokerage account?

knee-jerk unqualified response: One notion would be to limit your size to < 10th the open interest, if concerned your size may impact your fills.

This is a start to answer your question from the CBOE website:

Position and Exercise Limits
Limits vary according to the number of outstanding shares and past six-month trading volume of the underlying stock. The largest in capitalization and most frequently traded stocks have an option position limit of 250,000 contracts (with adjustments for splits, re-capitalizations, etc.) on the same side of the market; smaller capitalization stocks have position limits of 200,000, 75,000, 50,000 or 25,000 contracts (with adjustments for splits, re-capitalizations, etc.) on the same side of the market. The number of contracts on the same side of the market that may be exercised within any five consecutive business days is equal to the position limit. Equity option positions must be aggregated with equity LEAPS positions on the same underlying for position and exercise limit purposes. Exemptions may be available for certain qualified hedging strategies.

Ask your broker if their router offers preferenced liquidity. What would they expect to get filled on with sweep order?
No unusual market conditions or time I would expect at least 10,000 if you're on the Citadel or SIG router - at the posted b/a. Talk to your broker's help desk.
Greater size and I would get out of the retail system and work with a broker who can facilitate greater size.

Ask the Market Maker...
You can analyse the intraday volumes to get an estimate...

So I could have a position size of thousands of contracts in a SPY option and it would be a drop in the bucket/nothing significant?

There’s a guy on here who plans on trading 100,000 spx options at a clip. That’s a million SPY.

Might be significant for your wealth, but otherwise you should chat with your broker. S & P 500 products are pretty much as liquid as you get in equity derivates. Are you just on a fishing trip or do you have a genuine need?

Everyone is thinking about the dollar value of the underlying shares--including me.

And I did start to wonder, y'know, is this guy serious, why would someone with that kind of capital post this question in this forum, i.e., wouldn't they have access to better resources? And it doesn't help that the guy only has eleven posts in this forum.

But then I got to thinking...

The guy could be talking about, say, for example...

A position of 7500 vertical call spreads, with strikes that are only one dollar apart.

On a debit call spread that costs $.08, with a position size of 7500 contracts...

You only need $60,000 plus commission.

You don't need seven figures in your account to trade thousands of contracts in SPY options. You don't even need six figures.
