What is Max Pain?
Max Pain is the strike price at which option sellers (market makers) would lose the least amount of money if the stock expired at that price. The theory suggests stocks tend to gravitate toward this price near expiration.

Understanding PSA Max Pain
The PSA options chain represents Public Storage. Evaluate its open-interest distribution alongside business context that includes occupancy, property demand, financing costs, and interest rates. Compare Max Pain across available expirations because the distribution can differ from one expiration to another.
For PSA, the calculator tests each candidate strike against call and put open interest for the selected expiration. Review the full curve with the result. The calculation describes the selected chain and does not predict where Public Storage will trade.
How the PSA Max Pain calculation works
QuantWheel tests each strike as a possible expiration price. It adds the intrinsic value of open calls and puts at that price, weighted by open interest and the contract multiplier. The strike with the lowest combined value is displayed as PSA Max Pain.
This calculation uses the selected options chain. It does not measure dealer inventory, intent, future order flow or the probability that PSA will finish at the calculated strike.

PSA Max Pain FAQ
What is PSA Max Pain?
PSA Max Pain is the candidate expiration price where the combined intrinsic value of outstanding PSA calls and puts is lowest for the selected expiration. It is a calculation based on open interest, not a prediction of where PSA will trade.
How is PSA Max Pain calculated?
For each candidate price, QuantWheel calculates call and put intrinsic value across the selected PSA options chain, multiplies each value by open interest and the 100-share contract multiplier, then adds the totals. The candidate price with the lowest combined total is the Max Pain strike.
Which PSA expiration should I select?
Select the exact PSA expiration you want to examine. Weekly and monthly expirations can have different open-interest distributions, so compare them separately instead of applying one result to every date.
How should I use PSA Max Pain?
Compare the calculated strike with PSA price and the full call and put pain chart for the same expiration. Use it as expiration context alongside liquidity, gamma exposure and your own risk plan rather than as a standalone trading signal.
Is PSA Max Pain a price target?
No. PSA Max Pain does not forecast price and does not prove that traders or market makers will move PSA toward a particular strike. News, volatility, liquidity and positioning can outweigh any expiration-related pinning effect.
Is the PSA Max Pain calculator free?
Yes. QuantWheel provides a limited number of free PSA Max Pain calculations. The calculator shows how many free calculations remain before you run another expiration.
