Try Terminal

Lavender Terminal · for a trader running their own book

See your whole book. Then check the math.

An options workstation built on Greeks computed the way the contracts actually behave — American exercise, discrete dividends, real borrow — and repriced continuously against the live underlying. Every input is exposed and every difference has a named reason, so you never have to take a number on faith.

payment method required · no charge if you cancel before it ends · opens on a sample book, nothing to configure

Running a desk rather than your own book — several traders, your own clearing firms, orders going out to your executing brokers? That is Lavender Desk.

Live, right now

A live surface, not a screenshot.

Drag it. Everything below is what goes into it and what Terminal lets you do with it.

Drag sideways to pan across the surface.

liveYour whole volatility surface as one shape you can spin — in Terminal, with yesterday ghosted behind today.

Built by the founder of Derivix, acquired by FlexTrade.

Two decades building the analytics and execution systems professional options desks run on — now on your desktop, month-to-month, without the institutional overhead.


Modeled the way the contracts behave

American exercise, dividends treated as the discrete cash events they are, and a real borrow rate rather than an assumed one. Some vendors compute Greeks with Black-Scholes because it is fast — exact for European options, an approximation for the American ones you trade.

Institutional pricing, desk-sized cost

Correct American pricing is normally something you rent from an institutional vendor at institutional cost. Terminal puts it on your desktop for one flat price per seat.

Q1

What's my risk right now?

Everything you hold, together — live.

One grid, every position, every dollar-Greek, marked against Lavender's own analytics and moving with the tape.

Grouped the way you actually think about the book

Regroup the same book along whatever axis the question needs — by name, by expiry, by structure, by exposure — with a pinned total and live red/green heat on $delta, $gamma, $vega, $theta, $decay, $charm and $color. Second and third-order exposure in dollars, at the book level.

View the same risk grid as it stood 1, 5 or 30 days ago — not just live.

check every figure ties to the position rows above it

It doesn't just show the exposure. It hands you the hedge.

Set a policy band and Terminal returns the trade that closes the gap — instrument, direction, size, estimated cost, and the exposure you're left holding afterwards. One click works it into a paper account so you can see the book you would be left holding. Terminal never sends an order to your live account, or to the market — placing the trade stays with you, in your broker.

check you see the post-hedge book in paper before you place anything for real

Your live book, on our Greeks

Connect your live Interactive Brokers, tastytrade or Tradier account — one broker per seat — and your real positions are marked against Lavender's own Greeks. The connection is read-only: Lavender reads the book and never writes to it. Any trade you work in Terminal goes to a paper account, never to your live one. You can stage a hedge, see what it does to the book, and decide — with no way to put it on by accident.

check read-only on the live account · trades go to paper, never to the market

The whole chain, not just the strikes near the money

Every contract on the board carries independently computed IV and Greeks through third order — not interpolated from a handful of anchors, and not restricted to what's liquid.

check every surface is fitted to the whole chain, not a handful of anchors

Your legs, read as strategies

Terminal reads your legs back as the structures you actually put on, so a book of loose positions reads as the trades you meant to have rather than a list of contracts.

Q2

What happens if?

Mark your whole book across a grid of what-ifs. Then drop in a crisis.

Not a sensitivity estimate off today's Greeks. Every cell is your book, repriced.

P&L on the whole bookbig move downspot todaybig move upthe part an estimate missesestimated from today’s Greeksevery cell repricedschematic
fig. 01Near today's spot a sensitivity estimate is close enough. The further the market moves — which is when the question actually matters — the more it understates what a short-gamma book actually loses. Repricing every cell closes that gap.

Every cell a real reprice

Shock spot against volatility across a grid where each cell reprices the whole book through the American model rather than estimating from today's Greeks — which is what matters once the move gets large. Roll time forward through the same grid to see the shape change.

check run the same shock in your own model and compare cell by cell

Drop in a crisis

One click applies a crisis-scale stress — Crash 2008, Covid 2020, or a VIX spike — to the book you are holding right now, so the question stops being hypothetical and starts being specific.

Put odds on it

Monte Carlo across thousands of correlated paths — spot and volatility correlation exposed, not buried — reporting the full percentile spread, probability of loss, and CVaR at the tail. A portfolio spread across names is stressed as a portfolio, not as a pile of independent positions.

check the correlation matrix is inspectable, and path count and horizon are stated on the run

Find the move that hurts

Rather than guessing which scenario to test, invert the question: Terminal solves for the smallest move that breaks you and rings it on the grid.

Scenarios shock spot and volatility. Model any multi-leg idea on a risk-aware ticket and watch it flow through every view above before you commit — or paper-trade it and track it as a live position.

Q3

Can I trust these numbers?

Nothing here asks for faith.

The assumptions behind every number are exposed, the residual is shown rather than absorbed, and every difference from another source has a named reason.

Every dollar, explained

P&L attribution splits your day into delta, gamma, vega and time — and prints the residual in its own column. Most tools fold the unexplained remainder into the nearest bucket. If something doesn't tie out here, you will see it.

Check it against your own source

Every input behind a number — the dividends, the forward, the borrow — is shown on the way through, so each one can be compared with whatever you already trust. Our documentation carries the worked derivation.

American contracts are priced against the real discrete dividend schedule and a real borrow, so a closed-form check approximates them rather than reproducing them. Where the two disagree is where a simpler model is wrong, and the inputs on screen tell you which one it is.

check every input behind a number is shown, not assumed

The whole surface, and yesterday behind it

Spin your name's fitted volatility surface as a single shape, with T-1 ghosted behind today, alongside synchronized skew and term-structure views. A change in the shape of the surface becomes something you notice rather than something you reconstruct.

check the live surface is at the top of this page

Also included

Four more views that earn their place on the screen.

Vol regime

Where current implied volatility sits against its own history, so you know whether today is genuinely rich or merely higher than yesterday.

Earnings

The event priced into the front expiry, and what the surface expects it to do — the piece most models fold into a single number.

Rich / cheap strikes

Individual contracts measured against the fitted surface, so a strike trading away from its own curve is visible rather than inferred.

Pin risk

Short options sitting near strike into expiry, with the assignment and settlement consequences laid out before Friday afternoon.
