Understanding CSGP Max Pain
The CSGP options chain represents CoStar Group. 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 CSGP, 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 CoStar Group will trade.
How the CSGP 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 CSGP Max Pain.
This calculation uses the selected options chain. It does not measure dealer inventory, intent, future order flow or the probability that CSGP will finish at the calculated strike.

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