Understanding SO Max Pain
The SO options chain represents Southern. Evaluate its open-interest distribution alongside business context that includes power demand, regulation, fuel costs, and financing conditions. Compare Max Pain across available expirations because the distribution can differ from one expiration to another.
For SO, 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 Southern will trade.
How the SO 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 SO Max Pain.
This calculation uses the selected options chain. It does not measure dealer inventory, intent, future order flow or the probability that SO will finish at the calculated strike.
SO Max Pain FAQ
What is SO Max Pain?
SO Max Pain is the candidate expiration price where the combined intrinsic value of outstanding SO calls and puts is lowest for the selected expiration. It is a calculation based on open interest, not a prediction of where SO will trade.
How is SO Max Pain calculated?
For each candidate price, QuantWheel calculates call and put intrinsic value across the selected SO 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 SO expiration should I select?
Select the exact SO 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 SO Max Pain?
Compare the calculated strike with SO 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 SO Max Pain a price target?
No. SO Max Pain does not forecast price and does not prove that traders or market makers will move SO toward a particular strike. News, volatility, liquidity and positioning can outweigh any expiration-related pinning effect.
Is the SO Max Pain calculator free?
Yes. QuantWheel provides a limited number of free SO Max Pain calculations. The calculator shows how many free calculations remain before you run another expiration.
