Definitions

Trading Volume represents the notional value of trades, i.e. the product of the quantity of assets transacted and the trade price at the time the transaction was executed. The quantity represents the total U.S. dollar equivalent value of matched trades transacted between a buyer and seller through our platform during the period of measurement.

Average Trading Spread represents total commissions earned from transactions on the Bullish Exchange for the period, expressed as a percentage of the trading volume for the period. Management reviews this metric, which reflects the cost of trading on the Bullish Exchange, changes in fair value of perpetual futures, and rebates, for insight into the average revenue generated per unit of trading volume on our platform.

Volatility is calculated using 1-minute price intervals from CoinDesk Data's Adaptive Diversified Liquidity Index for BTC and ETH. We determine the daily volatility by measuring the standard deviation of these minute-by-minute price changes, which provides a more granular view of price fluctuations. This daily figure is then converted to an annualized volatility by multiplying it by the square root of 365, a standard practice for making risk metrics comparable over a one-year period.
