.BOPT30M: 30-minutes Optimism/Tether BitMEX Index TWAP

.BOPT30M Index Details

The BitMEX .BOPT30M Index is a 30-minute TWAP of the Optimism price from the .BOPT Index. These values are used for settlements. The TWAP is calculated every 4 hours.

This index is composite and hybrid, which means the price is built from multiple sources against multiple underlying currencies or cryptocurrencies. The Source Prices are converted to a common denominator using the corresponding BitMEX index. See the "Composite Index Breakdown" below for information on the constituents. If a constituent stops publishing or no trades are printed for over 15 minutes, BitMEX may automatically remove that constituent from the index until trading resumes.

Further information on the composition and calculation of BitMEX indices is available.
