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 AON Max Pain
The AON options chain represents Aon. Evaluate its open-interest distribution alongside business context that includes underwriting, claims, pricing, and investment income. Compare Max Pain across available expirations because the distribution can differ from one expiration to another.
For AON, 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 Aon will trade.
How the AON 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 AON Max Pain.
This calculation uses the selected options chain. It does not measure dealer inventory, intent, future order flow or the probability that AON will finish at the calculated strike.

AON Max Pain FAQ
What is AON Max Pain?
AON Max Pain is the candidate expiration price where the combined intrinsic value of outstanding AON calls and puts is lowest for the selected expiration. It is a calculation based on open interest, not a prediction of where AON will trade.
How is AON Max Pain calculated?
For each candidate price, QuantWheel calculates call and put intrinsic value across the selected AON 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 AON expiration should I select?
Select the exact AON 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 AON Max Pain?
Compare the calculated strike with AON 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 AON Max Pain a price target?
No. AON Max Pain does not forecast price and does not prove that traders or market makers will move AON toward a particular strike. News, volatility, liquidity and positioning can outweigh any expiration-related pinning effect.
Is the AON Max Pain calculator free?
Yes. QuantWheel provides a limited number of free AON Max Pain calculations. The calculator shows how many free calculations remain before you run another expiration.
