plugin-option-chain

Multi-vendor options chain straddle table for Jaspers Terminal: calls and puts side by side per strike with Bid, Ask, Last, Volume, Open Interest, Implied Volatility %, and Black-Scholes Delta, plus summary statistics (spot price, ATM IV, ATM straddle, put/call ratios, and max pain).

Install

In Jaspers Terminal, open Settings > Plugins, paste

https://github.com/JaspersAI/plugin-option-chain

and press Install, or install option-chain from Jaspers Hub.

Needs

This plugin makes no direct network calls and declares no keys of its own. Instead, it reads options and underlying data from whichever sibling data plugins you have installed:

• Yahoo (default): requires the yfinance plugin (yfinance/server MCP connection, no key required).
• Alpaca: requires the alpaca plugin (alpaca/option-chain and alpaca/stock-snapshots).
• Massive: requires the massive plugin (massive/option-contracts, massive/option-chain, and massive/previous-close).
• Databento: requires the databento plugin (databento/definitions, databento/quotes, and databento/underlying-ohlcv).
