Using Gamma Exposure to Scalp SPX Intraday

Key Concepts

• GEX (Gamma Exposure): A metric that measures the sensitivity of option prices to changes in the underlying asset's price, specifically focusing on the gamma of options. It helps identify potential "poles" or "traction points" in the market.
• Gamma Exposure Trades (GEX Trades): Trading strategies that leverage the insights gained from GEX analysis to predict market movements and execute trades.
• Intraday Scalping: A trading strategy focused on making small profits from minor price changes throughout the trading day.
• Zero Days to Expiration (0DTE) Trades: Options contracts that expire on the same day they are traded, offering high leverage but also high risk.
• Long Put Spread: A bearish strategy where a trader buys a put option and sells another put option with a lower strike price, limiting both potential profit and loss.
• Short Call Spread: A bearish strategy where a trader sells a call option and buys another call option with a higher strike price, limiting both potential profit and loss.
• Iron Butterfly: A neutral strategy that involves selling an at-the-money (ATM) straddle (a put and a call with the same strike price) and buying out-of-the-money (OTM) puts and calls with the same expiration date, creating a narrow profit range.
• Iron Condor: A neutral strategy that involves selling an OTM put spread and an OTM call spread, creating a wider profit range than an iron butterfly.
• Call Gamma/Put Gamma: Refers to the gamma of call options and put options, respectively. GEX analysis often looks at the balance between these.
• Pole/Traction Point: An area identified by GEX analysis where there is a balanced distribution of call and put gamma, suggesting the market might gravitate towards or be attracted to this level.
• Call Wall: An area with a significant amount of open interest in call options, which can act as resistance and potentially push the market price down as market makers hedge their positions.
• Market Makers: Financial institutions that provide liquidity in the market by quoting both buy and sell prices for securities. They often hedge their option positions, which can influence market movements.
• Hedging: The act of taking an offsetting position in a related security to reduce the risk of an existing investment.

GEX Trading Strategies and Examples

The video details the author's personal journey and experiences using Gamma Exposure (GEX) analysis for intraday scalping, primarily with 0DTE trades. The author emphasizes that this is a learning process and not a definitive guide, but shares specific trade examples to illustrate the application of GEX insights.

Trade 1: November 19th - Long Put Spread and Iron Butterfly

• Date: November 19th
• Strategy: Initially a long put spread, then converted to an iron butterfly.
• Rationale: The author observed a GEX profile with a balanced distribution of call and put gamma, identified as a "pole" or "traction point" around the 6650 level. The expectation was that the market might move back down to this level.
• Execution (Long Put Spread):
  • Entry: 9:57 AM
  • Position: Short 665 put, Long 660 put (0DTE).
  • Market Context: S&P was around 662 at entry. The GEX chart showed a balanced gamma profile around 6650.
  • Outcome: The market initially moved up slightly but then came back down into the anticipated range, oscillating around 6650 for most of the day. The author took a quick $50 profit.
• Execution (Iron Butterfly):
  • Entry: 12:43 PM (same day)
  • Position: Iron Butterfly centered at 6650.
  • Market Context: At this time, the market had moved down to 6606. The GEX profile showed significant negative gamma exposure, but the author was still anticipating a move back up to the 6650 "pole" level.
  • Outcome: The market did move back up towards 6650. The author risked $25 and made a profit, even though the position didn't close exactly at 6650.

Trade 2: November 21st - Narrow Iron Butterfly

• Date: November 21st
• Strategy: Iron Butterfly.
• Rationale: The author identified two "poles" in the GEX profile: one around 6600 and another at 6650. The market opened below these levels, and the author anticipated a move back up to the 6600 level.
• Execution:
  • Entry: 9:40 AM
  • Position: $5 wide Iron Butterfly at 6600, with a credit of $49.95. Risk was $5.
  • Market Context: Market opened at 6559. GEX showed balanced exposure around 6600 and 6650.
  • Outcome: The market moved up, touched and moved through 6600, then moved up to 6650. By the end of the day, the market closed at 6602, very close to the center of the butterfly. The author made $196 profit, despite not being able to take early profits due to the wide legs of the spread.
• Key Learning: The author realized they were too conservative with the $5 risk and should have scaled up to multiple contracts to capture a larger profit.

Trade 3: November 25th - Short Put Spread and Long Call Spread (Bearish Trades)

• Date: November 25th
• Strategy: Two bearish trades: a short put spread and a long call spread (which is equivalent to a bearish bet on the underlying).
• Trade 3a: Short Put Spread
  • Entry: 9:50 AM
  • Position: Short put spread 6650/6645 (0DTE).
  • Market Context: The market had dropped significantly to 6665. The GEX profile showed a prominent "pole" at 6700, suggesting a potential attraction point. The author anticipated a rebound towards 6700.
  • Outcome: The market moved back up to 6700, allowing the author to take a quick profit within two minutes.
• Trade 3b: Long Call Spread (Bearish)
  • Entry: 9:55 AM
  • Position: Long put spread 6690/6695 (0DTE).
  • Market Context: The market was around 6689, having rallied slightly. The author saw 6700 as potential resistance after the earlier move.
  • Outcome: The market fell back down slightly, allowing for a quick profit.
• Trade 3c: Short Call Spread (Bearish)
  • Entry: 12:35 PM
  • Position: Short call spread 6750/6755 (0DTE).
  • Market Context: The GEX profile had shifted. The market had rallied past 6700. The author identified 6750 as a potential "call wall" or barrier.
  • Outcome: The market moved slightly higher and then pulled back, allowing the author to scalp $75 profit. The author notes that the levels don't always hold perfectly.

Trade 4: December 3rd - Short Call Spread (Bearish)

• Date: December 3rd
• Strategy: Short Call Spread.
• Rationale: The GEX profile showed a massive concentration of call open interest around 6850, indicating a strong "call wall" that could act as resistance.
• Execution:
  • Entry: 1:22 PM
  • Position: Short call spread 6855/6860 (0DTE).
  • Market Context: The market had been steadily moving higher throughout the day, approaching the 6850 call wall. The author anticipated resistance at this level.
  • Outcome: The market eventually hit the 6850 level and then pulled back. The author took profits near the end of the day, indicating a longer holding period for this trade.

Trade 5: December 4th - Wider Iron Butterfly

• Date: December 4th
• Strategy: Iron Butterfly.
• Rationale: The GEX profile showed balanced gamma around 6850 and 6855, suggesting these could be "pull areas" or zones of attraction. Due to the balance and lack of a single dominant "pole," the author opted for a wider iron butterfly to capture more potential credit and profit.
• Execution:
  • Entry: 11:34 AM
  • Position: $10 wide Iron Butterfly, entered for a $670 credit, risking $330.
  • Market Context: The market was trading around the 6850-6855 levels. The author expected the market to gravitate within this range.
  • Outcome: The market danced around the 6850-6855 levels for most of the day. The author exited the position at 2:28 PM with a good profit, not holding it for the entire day.
• Key Learning: The author considered adding to the position or entering another one later in the day but chose to take profits. They also noted that a put spread could have been used to capture the upward move.

Trade 6: December 5th - Short Call Spread (Bearish)

• Date: December 5th
• Strategy: Short Call Spread.
• Rationale: The GEX profile showed a significant "call wall" at 6875 with very little put open interest. The author anticipated that the market, after opening at 6872, might face resistance at this call wall and potentially turn over.
• Execution:
  • Entry: 9:40 AM
  • Position: Short call spread 6875/6880 (0DTE).
  • Market Context: Market opened at 6872. The author expected a move down from the call wall.
  • Outcome: The market initially moved slightly higher before turning over and moving down. The author exited the trade at 11:28 AM with a $50 profit.
• Key Learning: The author felt they should have waited for the market to stretch a bit further beyond the 6875 level before entering, as markets can sometimes move slightly beyond identified levels. They also noted that the market eventually hit resistance around 6900, suggesting a potential missed opportunity for a larger profit or a second trade.

Author's Reflections and Areas for Improvement

The author concludes by reflecting on their learning process and identifying areas for improvement:

• Patience in Entries: Waiting for better entry points, allowing the market to stretch slightly beyond identified levels.
• Scaling Positions: Not being overly conservative and scaling up positions when good premium is available and the GEX analysis supports it.
• Multiple Positions: Exploring the strategy of layering multiple positions throughout the day rather than relying on a single trade.
• Market Environments: Gaining experience in different market conditions, such as heavy selling or buying pressure, and observing events like Fed days.

The author expresses enthusiasm for GEX trading as a "blue ocean" territory and encourages community feedback and sharing of ideas.
