If you’ve ever seen SPX or SPY gravitate toward a seemingly arbitrary level on a Friday afternoon, you might’ve witnessed expiration pinning in action. Some traders treat it like gospel. Others dismiss it as financial folklore. I used to be skeptical—until I started seeing it play out week after week.
After two decades in the options market, both manually and through automation, I’ve learned that institutional flows shape price behavior. What some call “max pain” is simply a reflection of how market makers manage risk into expiration. It’s not magic—it’s mechanics.
In my broader Max Pain Strategy Guide I break down the full framework, and in my data study Does Max Pain Really Work? Data From 100 SPX Expirations I show how often the theory actually lines up with closing prices. This article is the bridge between those two: the definition, the mechanics, and how I use it in real trading.
Here’s what this article will help you understand:
- What expiration pinning and max pain actually mean
- How to find the level where options lose most of their value
- Why I use this concept in my short-duration iron condor strategy
- How it supports the logic behind my Weekly Premium signal service
What Traders Mean by “Max Pain”
The term refers to the price at which the largest number of options—calls and puts—expire worthless. Also known as the maximum pain point, this level causes the greatest financial loss for option buyers and minimizes payouts from sellers.
Max Pain Simplified:
It’s the price where the fewest options finish in the money, benefiting market makers and hurting retail traders.
Traders calculate it using open interest across all strike prices in the expiration chain. The result isn’t a forecast, but a reflection of where dealers have the least exposure. It becomes more useful in high-volume markets like SPX or SPY where flows are more concentrated, and far less useful on illiquid tickers where open interest is scattered.
What Is the Role of Options in Max Pain?
Options are the entire foundation of the max pain calculation. The level is determined by analysing the open interest of all calls and puts in an expiration cycle. For each strike, you calculate how much money option buyers would lose if the underlying settled there.
The max pain price is simply the strike where the combined payout to option holders is lowest. Because market makers are typically net sellers of options, this is also the point where their overall exposure is smallest. That’s why price often gravitates toward this level in quiet markets: it’s the path of least resistance for dealer hedging.
Why SPX and SPY Respond to It More Than Other Assets
SPX and SPY consistently react to max pain levels because of their liquidity and institutional participation. Here’s why these tickers stand out:
- Open interest is massive
- Large funds and market makers dominate the order book
- Market makers actively hedge short premium exposure
| Instrument | Settlement | Typical Flows | Max Pain Behaviour |
|---|---|---|---|
| SPX | Cash-settled index | Institutional hedging, volatility and index desks | Cleaner pinning around major strikes in calm markets |
| SPY | Share-settled ETF | ETF flows, retail options, intraday arbitrage | Still responsive to max pain, but noisier and more prone to overshoots |
| Small-cap single names | Share-settled stock | Patchy open interest, episodic flows | Max pain usually too noisy to rely on |
SPY, while ETF-based and share-settled, shows similar effects to SPX. When I design 2–3 DTE iron condors, I always check the current SPY max pain zone for extra confidence in strike placement.

How to Estimate Max Pain for Any Expiration
You don’t need a spreadsheet to figure it out manually, although you could. Today, tools automate this using live open interest data. The calculation follows this process:
3-Step Process:
- For each strike, add the dollar value of all in-the-money puts and calls.
- Calculate total option payouts for each level.
- The strike with the lowest total payout is the max pain price.
Max Pain Formula:
Total losses for option buyers (calls + puts) are minimized at this strike.

Use Iron Condors That Respect These Levels
In Weekly Premium, I deliver automated SPX iron condors tuned to where price action is most likely to stabilize—not where we think it’ll go. That means using max pain logic as a filter—not a forecast.
- 2–3 DTE only: Enter midweek for Friday expiry
- Defined risk: Always risk-capped and balanced
- Automation: Set-and-forget execution through Tradier or IBKR
- 5% ROI goal: Based on edge, not guesswork

Why Expiration Pinning Happens Most on Fridays
When expiration nears and the calendar is clear, market makers aren’t adjusting their books aggressively. Instead, price tends to float toward where they’re least exposed. That’s often the max pain point.
It’s not manipulation—it’s the natural result of gamma neutrality and delta hedging unwinding as contracts approach zero DTE. This setup is perfect for defined-risk spread traders like us, especially in SPX where institutional positioning is concentrated.
My Strategy: Iron Condors Built Around Max Pain
Each week, I take the current max pain level into account when structuring credit spreads. Here’s my approach:
- Identify the most recent max pain estimate for SPX.
- Sell strikes just outside that zone (e.g., 5,090/5,110 if pain is at 5,100).
- Open the trade on Wednesday for Friday expiry.
- Automate through IBKR or Tradier for execution efficiency.
This setup benefits from theta decay, volatility crush, and price magnetism—without needing to be perfect on direction. In Weekly Premium, the same rules are codified and executed automatically.
Real Example: SPX Closing Near Max Pain
Expiration: May 10, 2024
- Calculated Pain Level: 5,200
- Actual Close: 5,203.45
- Conditions: No major events, low volatility, heavy open interest at 5,200
SPX drifted throughout the day and finished just above the expected level. That’s textbook expiration pinning—and exactly the kind of environment Weekly Premium thrives in.
What Is the Maximum Profit in Option Trading?
The maximum profit depends on the strategy:
For buyers of calls or puts, max profit is theoretically unlimited for calls and substantial for puts, but only realised if price makes a large directional move.
For sellers of credit spreads, like bull put spreads or iron condors, max profit is the credit received at entry. These strategies profit from time decay and stability, not prediction.
In max pain contexts, defined-risk spreads are often favoured because they avoid the blow-up potential of naked selling near crowded OI levels.
What Max Pain Is Not
- Not a prediction tool – It’s a positioning signal.
- Not dealer manipulation – It’s how they hedge risk.
- Not useful on low-volume tickers – Stick with SPX, SPY, or QQQ.

Frequently Asked Questions
What is the meaning of max pain in options?
It refers to the price where the largest number of options expire worthless, minimizing payouts from option sellers. In practice, it’s the level where dealers have the smallest net obligation if the market settles there.
Is max pain reliable for trading?
It can be, especially in calm markets with high open interest and low implied volatility. I treat it as a context layer, not a standalone signal—most useful when SPX or SPY is trading inside a range and the macro calendar is quiet.
Where can I find the current SPX or SPY max pain level?
Use tools like SwaggyStocks, Barchart, or OptionCharts.io for up-to-date estimates based on open interest. I normally cross-check at least two sources before I trust a specific level.
Should I place my short strikes at max pain?
Not directly. I usually place them just outside the pain level to give trades more breathing room. Max pain is often a crowded strike; I’d rather let price wobble around it without sitting my short strikes right on the bullseye.
Can I automate this strategy?
Yes. My Weekly Premium service does exactly that through platforms like IBKR and Tradier, using max pain, open interest, volatility, and trend filters to decide when to deploy or skip a trade.
Does max pain work the same for SPY as it does for SPX?
Not exactly. SPX is cash-settled and heavily driven by institutional desks, so pinning is often cleaner. SPY is share-settled and influenced by ETF flows and retail activity, so it tends to overshoot more. I explain the differences in detail in SPX vs SPY Max Pain.
Is there any data showing that max pain actually works?
Yes. In my article Does Max Pain Really Work? Data From 100 SPX Expirations, I walk through how often SPX closed near its max pain level, and under which conditions the effect was strongest.
