Options Time Value Calculator

Time value,
made visible.

A quick tool I made that fetches live crypto-options data and refreshes every few seconds, so I can see how much time value is left on my positions, the premium received since entry, and current unrealized P&L.

The time value calculator in action.
Why it exists

Manual time-value math is tedious.

Calculating time value by hand every time I sell in-the-money options takes time. This tool automates the calculation.

What it does

Live data, refreshed every few seconds.

It fetches live data and refreshes every few seconds, showing how much time value is remaining, the premium received since entry, and current unrealized P&L.

The boundary

Built for my own workflow.

It is not the most polished tool, but it works for me. It is built around how I actually trade crypto options.
