What this dashboard is
A reading instrument for an options book. It takes the positions you already hold, prices them against the option chain, and shows you what happens to them across the range of prices the underlying could reach.
What it does
- Groups your legs into strategies. A hundred shares and a short call are not two rows; they are a covered call, with one break-even and one payoff curve. The book is read as structures, not as a list of contracts.
- Prices what you hold, continuously. Every leg is marked, the greeks are summed per name and per account, and the payoff at expiry is drawn underneath.
- Looks for trades against what you own. Which written call is worth rolling, where a new spread could go, what a repair on an underwater lot would cost.
- Runs the book forward. Thousands of paths to a horizon for the distribution, or one path a day at a time for the experience of holding it.
What it is not
It prices precisely rather than predicting vaguely
Hand it a price and the chain it builds holds up against what those contracts really
traded at — a few percent out, measured rather than claimed. What it does not do is pick
one future and call it the answer. Instead it runs thousands of paths and shows you the
whole range, which is the honest shape of the question and, in practice, the more useful
one: you size a position against what could happen, not against a single guess.
- Not a broker. No order reaches a market. Nothing here is connected to money.
- Not advice. A suggestion is a candidate that passed a filter — a thing worth looking at, not a thing worth doing.
- Not live to the second. Stock prices are delayed 15–20 minutes. Option prices come from the last market close. Every page that shows a price says so.
The two questions
Before reading any number, know which question it answers. Nearly everything is one of these two, and they are easy to confuse because both produce a profit figure.
| Risk — all paths | Flight — one path | |
|---|---|---|
| Asks | Where could this end up? | What is it like to hold it? |
| Shows | A distribution at one horizon — the range, the chance of profit, whether margin breaks. | One realization, advanced a day at a time: today's mark, what expired, what was assigned. |
| Good for | Deciding whether a position is sane before you open it. | Finding out whether you could sit through the middle of it. |
A position can be sane on the distribution and unbearable on the path. The average of a thousand outcomes never shows you the Tuesday where the position is down 40% with three weeks to run — and that Tuesday is what usually decides whether a plan is followed.
Where the numbers come from
- Prices — delayed stock quotes and the last option close.
- Greeks — recomputed at the current price rather than taken as reported, so they track the stock rather than whenever the data vendor last refreshed.
- Model prices — where a contract has no usable quote, it is marked with a volatility model built from realized volatility plus skew and term structure. The dashboard labels these, and hovering shows the market's bid and ask beside them.
- Paths — drawn by resampling real historical moves for that name, not from a bell curve. Real markets have fatter tails than the normal distribution allows.
