Demonstration data — not live and not venue-verified. Equity perpetuals are derivatives, not shares.

Why this label

Lab

Illustrations, not scenarios the venue will print

The mark stays at the snapshot unless you are looking at the constructed path. A reference shock only moves the anchor in this page. Nothing here is a forecast, a hedge, or a recommendation.

Demonstration · Snapshot 25 Sep 2026, 20:00 UTC · Not a live feed, venue quotation, or verified term.

Open the contract page. Status: Trading. Confidence is on that page, not repeated here as a signal.

Constructed path

The reference is flat because this book has one anchor. The mark walk ends on the snapshot. It is not a historical tape.

Last eight constructed funding prints

Clamped to the sample cap and floor. The last row is the snapshot rate. Positive means longs pay shorts.

Constructed depth ladder

Reference shock

The snapshot mark stays put. Only the anchor moves, so basis changes. This is not how a venue marks a contract through an event.

Maintenance-distance sketch

Textbook isolated sketch: distance is initial margin minus the sample maintenance fraction. It is not the venue bankruptcy price, and it ignores fees, funding and gaps.

Initial margin 50.00%. Maintenance 2.50%. Buffer 47.50% of the entry.

Illustrative level US$93.83. Not a liquidation prediction.

Carry sketch at the snapshot rate

Holds the current funding print constant. That is the assumption, and it is the part that fails first.

Funding rates vary continuously. This is an illustration, not a forecast of cost, return, or profitability. Assumptions: constant rate, constant notional, no price change, no liquidation, and the sign convention that a positive rate means longs pay shorts.
