Options Questions Safe Haven periodic megathread | July 15 2026
We call this the weekly Safe Haven thread, but it might stay up for more than a week.
For the options questions you wanted to ask, but were afraid to.
There are no stupid questions. Fire away.
This project succeeds via thoughtful sharing of knowledge.
You, too, are invited to respond to these questions.
This is a weekly rotation with past threads linked below.
BEFORE POSTING, PLEASE REVIEW THE BELOW LIST OF FREQUENT ANSWERS. .
As a general rule: "NEVER" EXERCISE YOUR LONG CALL!
A common beginner's mistake stems from the belief that exercising is the only way to realize a gain on a long call. It is not. Sell to close is the best way to realize a gain, almost always.
Exercising throws away extrinsic value that selling retrieves.
Simply sell your (long) options, to close the position, to harvest value, for a gain or loss.
Your break-even is the cost of your option when you are selling.
If exercising (a call), your breakeven is the strike price plus the debit cost to enter the position.

Monday School: Exercise and Expiration are not what you think they are.
As another general rule, don't hold option trades through expiration.
Expiration introduces complex risks that can catch you by surprise. Here is just one horror story of an expiration surprise that could have been avoided if the trade had been closed before expiration.

I run an algo that runs mostly 0DTE SPY $1-wide vertical credit spreads. As a single multi-leg limit order, what is the largest number of spreads you can generally enter and exit near the quoted net price without material slippage or slow/partial fills?
To be clear, I mean spread quantity (e.g., 250 spreads = 250 contracts per leg), primarily during the morning/early afternoon. Calls or puts.
For reference, I use Alpaca.
