Multi-leg builder on a live chain
Start from a named structure or a blank ticket, pick strikes from the chain, then drag them on the payoff chart. T+N and implied-vol sliders show how the trade ages.
Journal every options trade. Adjust with your eyes open.
GreeksLedger is an options strategy journal built around adjustments: model multi-leg positions, compare payoff before and after every change, and keep a visual history of what you did and what you considered.

Built for the part of options trading nobody journals well
Most tools stop at entry. GreeksLedger is organised around what happens after: the roll, the add, the partial close, and whether it was the right call.
Adjustments as a first-class workflow
Model rolls, adds and closes as drafts, compare before and after payoff side by side, and commit the one you choose. Every adjustment becomes an event in the position's history.
Greeks and risk, per position and in total
Delta, theta, vega and gamma across the book, plus max profit, max loss, break-evens, probability of profit and an estimated margin for every structure.
A journal that remembers context
Each open or adjust freezes a market snapshot: spot, chain, rates, dividend yield. Fills, notes and events stay attached, so you can see what you knew when you decided.
Performance by strategy and underlying
Realized P&L, win rate, profit factor and expectancy over any period, broken down by ticker and by strategy type, so you learn which setups actually pay.
AI review with your own key
Bring a Claude or OpenAI key for trade reviews and adjustment proposals. Keys are encrypted at rest and never shared between accounts.
What it looks like
Real screens from the app, dark theme. A light theme is one click away.
How it works
Build
Pick an underlying, choose a structure, set strikes on the chain or the chart. See greeks, break-evens and POP update as you go.
Save
Save the trade to your journal with its fills and a frozen market snapshot. Group positions by account or theme.
Adjust and review
When the market moves, draft adjustments, compare them, commit one. Later, review the whole history and your realized performance.
Questions
Is GreeksLedger a broker?
No. GreeksLedger tracks and models strategies; it does not route orders or hold funds. You keep trading where you trade today and journal here.
Is the market data real-time?
The free tier uses delayed quotes and option chains, which is fine for review and planning. Real-time pricing through your own broker connection or data key is on the roadmap.
How do I get access?
GreeksLedger is in early access and we admit people in small batches. Join the waitlist and we will email you when your seat is ready.
What does it cost?
Nothing during early access. A paid tier for real-time data is planned; the journal and builder stay free for early-access users.
Do you see my AI keys or my trades?
Your AI keys are encrypted at rest with a server-side secret and used only for requests you trigger. Your journal data belongs to you; see the privacy policy for details.
