MIAX uses a more robust Simple Variance Swap methodology to calculate VSPIKES, which allows for both jumps in the underlying asset and discrete time monitoring. The VSPIKES Index is being disseminated through the Options Price Reporting Authority (OPRA) and traditional market data vendors. More information on VSPIKES can be found here.

SPIKES Futures are based on the SPIKES Volatility Index, which was designed by T3 Index and measures the expected 30-day volatility in the SPDR® S&P 500® ETF (SPY), the most actively traded ETF in the world. The futures contracts are listed on Minneapolis Grain Exchange, LLC (MGEX™) and accessed via the CME Globex® platform. The SPIKES Volatility Index is calculated and disseminated every 100 milliseconds, offering best-in-class accuracy and stability as a result of its proprietary price-dragging technology. Futures on the SPIKES Index allow traders to benefit from the Index’s innovative design features, including its truncation methodologies and underlying SPY option component liquidity.
