Overview
The Option Chains window provides a tabular view of every listed option contract for a given ticker — calls on the left, puts on the right, organized by strike and expiration. It surfaces the raw data that powers Ohey's derivative analytics: open interest, volume, bid/ask, implied volatility, and all major Greeks per contract.

Key Features
- ITM / ATM / OTM highlighting: In-the-money, at-the-money, and out-of-the-money rows are color-coded for instant visual identification.
- Multi-expiration browsing: Switch between expirations using the date selector. View weekly, monthly, and quarterly chains for the same underlying.
- Strike filtering: Narrow the display to a specific strike range. Focus on the strikes around the current price for day-trading, or expand for portfolio hedging.
- Greeks per contract: Delta, gamma, theta, vega, and rho displayed for each individual option contract.
- Volume and OI columns: Daily volume and open interest side-by-side for each strike — identify unusual activity at specific strikes and expirations.
- Guide Panel: Built-in educational overlay explaining how to read the chain, what each column means, and common analysis patterns.
Columns Reference
| Column | Description |
|---|---|
| Bid / Ask | Current best bid and offer for the contract. The spread indicates liquidity. |
| Last | Most recent trade price. |
| Volume | Number of contracts traded today. |
| OI | Open interest — total outstanding contracts at this strike/expiry. |
| IV | Implied volatility for this specific contract. |
| Delta (Δ) | Price sensitivity per $1 underlying move. |
| Gamma (Γ) | Rate of delta change per $1 underlying move. |
| Theta (Θ) | Daily time decay in dollars. |
| Vega (ν) | Sensitivity to 1% IV change. |
Use Cases
- Unusual activity screening: Scan for strikes with volume significantly above OI — indicates new positions being opened today.
- Spread construction: Use the chain to identify legs for multi-leg strategies (verticals, butterflies, condors). Compare bid-ask spreads to ensure execution quality.
- IV analysis by strike: Compare IV across strikes to identify skew opportunities. Pairing this view with the IV Skew window gives both tabular and visual perspectives.
