Explains contract repricing

Features

Built for how options traders actually think.

Everything on the website is centered around understanding the contract itself, not just the underlying ticker.

History

Historical contract tracking

See how a contract moved over time with price history, IV changes, daily volume, relative volume, and open interest in one clean snapshot.

Attribution

What moved the contract

Break down contract performance into underlying move, IV expansion, theta decay, gamma effects, and residual repricing so you can see what actually drove P&L.

Review

Journal and replay

Save your thesis, track entries and exits, and review what happened after the trade with timeline context and a cleaner post-trade workflow.

How it works

See the contract, the environment, and the reason for the move.

Track a contract

Monitor price, IV, volume, spread, and open interest with a clean historical view.

Read the environment

Use IVR, IVP, relative volume, and day volume to quickly understand whether the setup is calm, elevated, or active.

Review the attribution

Break the move into direction, volatility, decay, and repricing so you can see why the trade actually worked or failed.

Why it’s different

Most tools show options data. Volt interprets it.

Know whether the contract was stock-driven, vol-driven, or theta-dragged.

Understand whether today’s activity is normal or unusual with relative volume and day volume context.

Review trades later with timeline notes instead of trying to remember what the chart looked like.

Keep everything in a dark, minimal website that feels fast and premium instead of cluttered.
