About Lavender Trading Solutions

Two decades building the systems options desks run on.

Lavender delivers the modeling professional desks require — discrete dividends, early exercise, a real borrow rate — without institutional barriers or institutional cost. Rigorous quantitative modeling and production-grade infrastructure, for the desks that carry real options risk.

How we operate

One engine, every screen, no divergence.

Lavender Desk runs a trading desk. Terminal runs a trader's own book, Gateway runs in your code, and Discord is free to try. All of them compute on the same engine — so the risk screen and the risk API cannot tell two different stories.

Independently computed

Every Greek is computed by Lavender rather than passed through from a vendor. That is what makes an independent second source meaningful — two feeds from the same upstream model agree by construction, which tells you nothing.

Nothing hidden behind the number

The inputs behind each figure — dividends, forwards, borrow — are exposed on the way through. P&L attribution prints its residual rather than folding it into the nearest bucket.

The right people on the book

On Lavender Desk, each trader sees and trades only the accounts you give them; a risk manager sees everything and trades nothing, and every order and action is on the audit trail. On Terminal, the broker connection is read-only and any trade you work goes to a paper account.

Correct by default

Rigorous, correct defaults out of the box. Configurability sits on top of them, never instead of them — so the numbers are right before anyone has touched a setting.

Run for you

We connect your clearing firms and executing brokers, host the sessions and keep it running. We set it up and keep it running.

A letter from the founder

Why I built Lavender.

For more than two decades, I've built the systems that professional options traders rely on every day.

I founded Derivix in the mid-2000s and built its core directly — pricing models, volatility analytics, risk engines, the montage, and the execution stack. Derivix grew into a respected institutional platform and was eventually acquired by FlexTrade. That experience taught me what traders truly need: clarity, speed, accurate analytics, and tools that stay out of the way.

Over those same two decades, I've worked with a handful of firms, large and small, and with dozens of traders. Together they deepened my understanding of what traders need, and of how to deliver it with elegance and simplicity. They helped shape my thinking on what a desk requires in risk management, in execution, and in back-office support.

Meanwhile, technology moved on, and it was time for something more modern: one system covering the full trade lifecycle. Lavender is where decades of experience — especially what began at Derivix — come together.

So I built Lavender Trading Solutions. Lavender is the system I always wished existed: fast, accurate and intuitive, built on modern infrastructure — and built for the desks that carry real options risk.

Every decision in Lavender reflects what professional options trading actually demands: desk-wide risk and trading on one screen, connected to the clearing firms and executing brokers a desk already uses, and run for them. Risk you can trust and execution you can rely on, working together on every trade.

That's why I built Lavender.

Both, done well

A desk should not have to choose between seeing the risk and acting on it.

Every handoff between systems costs time and adds error. Lavender puts the whole loop — work the order, see the position, see the risk — on one screen, connected to the clearing firms and executing brokers your desk already uses.
