AlphaGBM Greeks
Prerequisites
- API Key: Set env
ALPHAGBM_API_KEY(formatagbm_xxxx...). - Base URL: Default
https://alphagbm.zeabur.app. Override with envALPHAGBM_BASE_URL.
What This Skill Does
Provides a comprehensive Greeks dashboard for any single option contract or multi-leg position. Calculates first-order and second-order sensitivities, and generates scenario heatmaps showing how Greeks change as price and IV move.
Greeks Covered
| Greek | Order | What It Measures |
|---|---|---|
| Delta | 1st | Price sensitivity -- how much does the option move per $1 in the underlying? |
| Gamma | 1st | Delta sensitivity -- how fast does delta change? (acceleration) |
| Theta | 1st | Time decay -- how much value does the option lose per day? |
| Vega | 1st | IV sensitivity -- how much does the option move per 1% change in IV? |
| Rho | 1st | Interest rate sensitivity -- how much does the option move per 1% rate change? |
| Charm | 2nd | Delta decay -- how does delta change as time passes? (delta-theta cross) |
| Vanna | 2nd | Delta-vol cross -- how does delta change as IV moves? |
| Volga | 2nd | Vega convexity -- how does vega change as IV moves? |
Position-Level Analysis
For multi-leg positions, the skill aggregates Greeks across all legs and shows:
- Net Greeks: Total delta, gamma, theta, vega for the combined position
- Greeks per unit of capital: Normalized by margin requirement or net debit
- Risk concentration: Which leg contributes most to each Greek
API Endpoints
