EP2: TWI x OD Gamma Playbook Review + Q&A
Trade With Insight
Overview
This video explains how to use options dealer positioning data, specifically focusing on gamma and charm, to identify potential support and resistance levels for trading SPX. The presenters emphasize the importance of using institutional-grade data, like that provided by Options Depth, over 'naive' gamma data. They demonstrate how to interpret gamma flips and charm flips as key pivot points that can signal likely price rejections, especially in trending markets. The discussion also touches on the concept of 'magnetic' price levels and how dealer positioning provides a more quantifiable and actionable approach to technical analysis compared to traditional methods.

Chapters
- Retail traders now have access to sophisticated tools like Options Depth to analyze options dealer positioning and gamma.
- Not all gamma data is equal; 'naive' gamma often misinterprets order flow, while Options Depth provides institutional-level, accurate data.
- This data helps identify potential rejection points and trading strategies based on dealer hedging behavior.
- The TWI (Trade With Insight) team uses this data to develop a 'gamma playbook' for reviewing trades.
Understanding the source and accuracy of gamma data is crucial for making reliable trading decisions, as flawed data can lead to poor execution.
The presenters highlight that Options Depth's data is more expensive because it's derived from institutional-level analysis, unlike cheaper, less accurate 'naive' gamma providers.
- The Gamma Flip is the price level where dealer gamma exposure shifts from negative to positive (or vice versa) for the day.
- The Charm Flip is the level where dealer charm exposure shifts between suppressive and supportive.
- Trading into these pivots, especially from below in a negative gamma environment, can lead to significant rejections and accelerated moves.
- These pivots act as potential resistance or support levels where traders can look for shorting opportunities.
Identifying these specific pivots provides actionable levels for entering trades, particularly short positions, by anticipating price rejections.
If price moves up into the Gamma Flip in a negative gamma environment, it's likely to reject, offering a shorting opportunity with potential for a large downside move.
- In a negative gamma environment, price moving up to the Gamma Flip can act as a ceiling.
- The first test of the Gamma Flip rejected, and a subsequent retest also resulted in rejection.
- When price rejects the Gamma Flip and moves lower in a negative gamma environment, the downside move accelerates.
- Breakdown by strike shows large dealer long gamma above (resistance) and short gamma below, creating an 'air gap' for rapid downward movement.
This example demonstrates how understanding dealer positioning and gamma flips can lead to profitable short trades with defined risk and high probability of significant moves.
Yesterday's trade where the SPX rejected the Gamma Flip around 6650 and moved down to 6570, illustrating an accelerated downside move due to negative gamma.
- The second example uses the Charm Flip as a rejection point, especially relevant in bearish market conditions.
- Opening directly below the Charm Flip often signifies it will act as a ceiling for the day.
- A second backtest of the Charm Flip provided another shorting opportunity.
- In a negative gamma environment, rejecting this level can lead to a rapid sell-off due to lack of supportive positioning below.
This illustrates how market context (e.g., bearish trend) combined with specific pivots like the Charm Flip can create high-probability short setups.
On Friday, the SPX opened below the Charm Flip at 6590, rejected it twice, and subsequently sold off over 50 points, confirming its role as resistance.
- Naive GEX relies on open interest, which doesn't distinguish between buyer and seller or market maker vs. retail positions.
- Accurate dealer positioning requires real, signed exchange data that identifies who is buying or selling.
- Options Depth uses this signed data to accurately track market maker hedging, providing actionable insights.
- This distinction is critical because market maker hedging is what drives significant price movements at key levels.
Using accurate dealer positioning data allows traders to understand the true forces driving price action, rather than relying on potentially misleading open interest data.
Elias explains that open interest of 1,000 contracts doesn't tell if market makers are net long or short, whereas signed exchange data reveals their actual position.
- Market maker long option positions can act as both support/resistance and have a 'magnetic' effect due to charm (time decay).
- Market maker short option positions, especially with negative gamma, can cause price acceleration away from those levels.
- A 'white' landscape (low gamma and charm) means price is more vulnerable to small flow changes.
- Trend days often occur with specific combinations of positive gamma and supportive charm, or significant customer short options creating a tailwind.
Differentiating between the effects of gamma (hedging response to price change) and charm (hedging response to time decay) provides a deeper understanding of price behavior at key levels.
Market maker long positions create a magnetic pull towards them due to time decay, while short positions with negative gamma can accelerate price away from them.
- The TWI bundle integrates Options Depth data with TWI's commentary and alerts into a customizable widget.
- The goal is to simplify complex data into actionable trading strategies, not necessarily to become an expert in all the mechanics.
- Quantifiable dealer positioning confirms traditional technical analysis levels, adding a layer of confidence.
- This data provides a roadmap for the day, helping traders manage expectations and make better decisions.
By simplifying complex data and integrating it into a usable format, traders can leverage advanced analytics for more effective decision-making without needing a deep theoretical understanding.
The TWI feed can be pulled into the Options Depth platform, allowing users to see both the data and the TWI team's real-time commentary and alerts in one place.
Key takeaways
- Accurate options dealer positioning data, like that from Options Depth, is essential for identifying reliable trading levels, far superior to 'naive' gamma.
- Gamma flips and charm flips are critical intraday pivots that can signal potential price rejections and trading opportunities.
- In negative gamma environments, rejections at resistance levels can lead to accelerated moves to the downside.
- Understanding whether market makers are net long or short options at specific strikes is key to anticipating their hedging actions and subsequent price impact.
- Dealer positioning data quantifies the significance of support and resistance levels, adding a crucial layer to traditional technical analysis.
- While complex, the application of dealer positioning data can be simplified into actionable trading strategies and daily roadmaps.
- The 'magnetic' effect on price is primarily driven by charm (time decay) on long dealer positions, while short dealer positions with negative gamma can accelerate price moves.
