The Call Resistance is the strike price with the highest net call gamma exposure. It represents a zone where dealers have significant exposure to call options, and therefore are likely to hedge more actively as price approaches.
On the Net Gamma Exposure Chart, Call Resistance is identified by the widest green bar—indicating the largest buildup of call gamma at a specific strike.
Here’s why it matters:
- As price approaches the Call Resistance level, dealers who are long gamma begin to sell the underlying asset (futures) to stay delta neutral. This selling can create resistance to further upside movement.
- Many traders also take profits or close positions at this level, reinforcing the potential for a pullback or pause in price.
- If the market is strong, call buyers may roll their positions up to higher strikes. This can cause Call Resistance to shift higher—and dealer hedging behavior to shift from selling to buying again.
So, Call Resistance is not just a technical ceiling—it’s a structural ceiling driven by options positioning and dealer flows.
We have created a Video Tutorial to show you how to use and trade the Call Resistance Level.
How to trade the Call Resistance Level
Let’s walk through two primary scenarios for trading Call Resistance (CR)—Rejection and Breakout.
Call Resistance Rejection
When price rallies into the Call Resistance level, it is approaching a zone with the highest net call gamma exposure. This is where dealers—who are often long gamma need to sell the underlying (e.g., futures) to stay delta-neutral.
Here’s the mechanical flow that creates resistance:
- Dealer Hedging Pressure. As price nears CR, delta increases rapidly on the calls dealers are short. To stay neutral, they must sell more futures. This creates real, mechanical selling pressure into the level—even if no news or fundamentals suggest resistance.
- Profit-Taking from Longs. Many retail and institutional traders use options to express bullish views. As price reaches the strike where these calls were purchased, traders begin to take profits. This leads to call closing, which causes dealers to unwind long hedges—again, selling the underlying.
- Flow Imbalance. Without fresh call buyers or bullish positioning above CR, the hedging flows dominate. This is often why price stalls, rejects, or reverses at CR—even when it seems technically “bullish.”
- Psychological Layer. CR often aligns with round numbers or prior highs, adding psychological resistance that reinforces trader behavior (profit taking, short entries, etc.).
So in a positive gamma regime, dealers sell into strength and buy into weakness to stay delta-neutral. That’s why CR often acts as a ceiling in this context.
Here is an Example on PLTR.
Call Resistance Breakout
We then have a second scenario where we can trade the Breakout of the Call Resistance. This is where Call Resistance becomes an Inflection Point for an upside momentum.
What’s Happening Behind the Scenes?
- Call Buyers Step In. As price approaches CR, bullish traders start opening or rolling call positions to higher strikes.
- Dealer Hedging Flips. Dealers, who were previously long gamma (hedging against price), now face rising delta exposure on new calls. Especially near expiration or in fast-moving markets, dealers may become short gamma and must hedge with the price—buying futures as price rises.
- Structural Shift. CR is no longer a ceiling—it becomes a support zone. On the retest, price holds above the level, confirming that dealers and traders are reinforcing the new higher strike structure.
Here is an Example on the Call Resistance Breakout.
