// - Resistance levels (red): Negative gamma, potential price ceiling
// - Support levels (lime): Positive gamma, potential price floor
// - Zero Gamma (yellow): Gamma flip point - thicker line for visibility
// - Max Pain (purple): Strike with maximum option value decay
// - Color intensity: Darker = stronger level (top levels are most prominent)
// - Labels show strike prices, GEX values, and ranking for easy reference
// - Focus on TOP 3 levels for key trading decisions
