EVIDENCERESEARCHEXECUTION

Options expire.
Evidence doesn’t.

Catch prices that don’t add up, check they hold at your size, and decide what’s worth trading on Derive. Then see how it actually played out.

From first signal to final outcome.

Every step is recorded, so you can always see why you acted on an idea, or why you didn’t.

  1. 01

    Catch what doesn’t add up.

    SkyLark flags where a mark and the displayed book disagree, and tells you whether the quote was fresh, wide or one-sided when it happened.

  2. 02

    Check it at your size.

    See whether the opportunity survives at the size you would actually trade. For options, weigh an outright against a same-expiry vertical. Not enough size is a valid answer.

  3. 03

    Ideas become priced, versioned intents. Nothing reaches Derive until you authorise it, within limits you set on size, price, fees and expiry.

  4. 04

    See how it played out.

    Outcomes are measured against what you set out to test and scored apart from fills, including the trades you decided not to take.

The whole story, on one screen.

The thesis, what would confirm or falsify it, the book against the mark, and every piece of evidence behind it, down to the payload hash.

Workbench · Episode viewFixture data · Simulated venue
SkyLark workbench episode view on fixture data: the thesis and what would confirm or falsify it, a book versus mark chart with a missed capture shown as a gap, the revision ledger, and claims linked to evidence with payload hashes.
A missed capture stays a visible gap. The full workbench is built for desktop.

Four clocks on every price.

Every price carries all four, in UTC, so any decision can be replayed against the evidence that existed at the time.

  1. t1 · Source

    Event time

    When the venue says the price was set. If the venue doesn’t say, SkyLark won’t guess.

  2. t2 · Receipt

    Received

    When the quote actually reached SkyLark, so you know how old it was when you looked.

  3. t3 · Slot

    Scheduled

    The capture slot it belongs to. A missed slot shows up as a gap, never a silent hole.

  4. t4 · Analysis

    Calculated

    When the analysis ran and on which version, so any result can be reproduced exactly.

A ledger, not a feed.

Every idea keeps its full history: each revision, each explanation you ruled out, each assessment. Research can shape a trade. It can never place one.
