DYDX Open Interest Statistics:
DYDX Aggregated Open Interest Chart:
DYDX open interest aggregated = open interest of coin-margined contracts + open interest of stablecoin-margined contracts converted to USD (notional value). For the moment only DYDX/USD, DYDX/USDT and DYDX/BUSD contracts are included. See the indicator settings, you can select/deselect individual contracts.
There are two other indicators that display raw open interest: aggregate open interest coin-margined contracts (value unit = USD) and aggregated open interest stablecoin-margined contracts (value unit = DYDX). See the chart indicators window.
This chart is not updated in real-time yet. For real-time charts please see the Markets page, you can find the aggregated indicators there too.
