SPY Daily Gamma Levels [Manual Input With Alerts]

Overview This indicator plots key options-based support and resistance levels (Gamma Exposure / GEX) directly on your chart. Unlike standard technical analysis, these levels (Call Wall, Gamma Flip, Put Support, and Volatility Trigger) represent where Market Makers are positioned, often acting as "magnets" or "repellents" for price action.
Important Note: TradingView Pine Script cannot currently access external options open interest data natively. Therefore, this is a Manual Input Indicator. You must update the four price levels in the settings each morning before the market opens.
Key Features:
4 Key Levels: Plots the Call Wall, Gamma Flip (Zero Gamma), Put Support, and Volatility Trigger.
Auto-Cleaning: Automatically deletes yesterday's lines to keep your chart clean; lines only show for the current session.
Alerts Included: Built-in alert conditions allow you to set notifications when price crosses the Gamma Flip or breaks the Vol Trigger.
Customization: Fully customizable colors and line styles.
Best Practices:
Timeframe: Works best on 15-minute charts for trend identification and 5-minute charts for entry execution.
Strategy:
Above Gamma Flip: Market generally stabilizes; dealers buy dips.
Below Gamma Flip: Volatility expands; dealers sell rips.
Below Vol Trigger: "Danger Zone" – expect accelerated selling pressure.
How to Get the Data (The AI Workflow)

1. The Prompt You can ask Gemini (or your preferred AI) the following prompt manually each morning:

"Can you schedule a daily task to search for these SPY Gamma levels and send them to me every morning at 8:00 AM?"
3. Updating the Chart
Receive the notification from the AI.
