Perps Tracker

Each row is a Parchment perpetual from Parchment's public API. A market is left out only when Parchment marks it disabled or delisted. These figures are not Aftermath Perpetuals. Aftermath runs a separate on-chain order book; its volume and open interest are not shown here and are not added to these numbers.

The price is Parchment's oracle mid, the storage price a normal fill uses. Parchment's documentation says each market is priced by a Pyth Lazer feed. It is not a last trade and not a mark price, and there is no bid or ask. A missing mid is left blank. A stale mid is labeled stale. Zero is not used in place of either.

The 24-hour change compares that mid with the newest Parchment price at or before the start of the stats window. The window is a rolling 24 hours when Parchment's since and until timestamps are a day apart; otherwise the change is left blank instead of being called 24h. 24h notional is USDC opened plus USDC closed or liquidated in that window. Open interest is the open long notional and the open short notional, shown separately. The two sides are not netted and are not added into one figure. USDC is shown one-for-one in dollars. A reported zero is shown as zero.

Parchment does not charge funding, and this API does not publish a funding rate, so none is shown. An equity market can be session-closed; that is the feed's session, not a missing price. Readings refresh about once a minute from one shared server cache. This is not financial advice.
