An official announcement on October 22, 2026 stated that XYZ100/USD trading was live. The official market record identifies it as a Cross-Exchange market routed to an external venue. The venue's specification index describes XYZ100 as tracking a modified market-capitalization-weighted index of 100 of the largest, most actively-traded, non-financial companies listed on a U.S. stock exchange, a benchmark for large-cap U.S. technology and growth equities. The October 22 announcement is the news hook. The more durable question is how a perpetual contract on a stock index is priced and run after the underlying cash session closes.

Why It Matters

When an index perpetual trades outside the underlying cash session, its pricing mechanism needs a reference beyond the live cash index. According to the venue's equity indices documentation, during the cash session the spot index value is used directly as the oracle price. Outside the cash session, but within futures trading hours, the oracle price is derived from the corresponding index futures price, discounted to an implied spot value using an exponentially weighted discount rate established during the prior cash session. The same page says that rate carries forward unchanged until the next cash session opens. In plain terms, the overnight oracle reference price estimates an implied spot index value using futures prices and a discount rate observed during the cash session. Orders execute on an external order book, so the execution price may differ from that reference. If futures and the index drift apart in ways the daytime basis did not capture, the estimate may differ from where the index opens. Gaps between the close and the next open are a feature of how a closed market is represented, not necessarily a malfunction.

The calendar matters just as much as the formula. The specification index lists XYZ100 external session hours from Sunday 6:00 PM ET to Friday 5:00 PM ET, a daily maintenance window from 5PM ET to 6PM ET, Monday to Thursday, and says trading also follows futures holiday closures. These external session hours do not by themselves establish when routed orders remain available during internal sessions, maintenance windows or futures holidays. It also lists a maximum leverage of 30x and a discovery bound of ±3.5% for XYZ100, though the page does not define the discovery bound in detail, so treat that figure as a published parameter rather than a guarantee about how prices move. Open interest is capped per market, and once the cap is reached only existing positions can be reduced or closed.

Funding and routing complete the picture. The platform's trading rules say funding settles hourly between longs and shorts at the venue's rate, and that a positive rate means longs pay shorts. A trader holding a position for several days therefore pays or receives funding on an hourly schedule, not a daily one. The same page says liquidation is executed by the venue, with its own timing and handling. More broadly, when orders are routed to an external order book, price, depth, trading hours and limits follow that venue instead of the platform where the order was placed. For a trader, that means reading the venue's rules, not the front end's habits, before sizing a position through a gap or a maintenance window. None of the pages reviewed says how a position is handled during a maintenance window, so that is worth confirming first.

On LeverUp, XYZ100/USD is identified as a routed Cross-Exchange market. These markets use a separate USDC balance, as described in the cross-exchange overview. This is educational, not financial advice.
