FTM Open Interest Statistics:
FTM Aggregated Open Interest Chart:
FTM open interest aggregated = open interest of coin-margined contracts + open interest of stablecoin-margined contracts converted to USD (notional value). For the moment only FTM/USD, FTM/USDT and FTM/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 = FTM). See the chart indicators window.
