After each rebalancing, recalculate the quantities of the spot and futures sides based on the product's net value[48] - **Rebalancing Rules**: Continuously hold quarterly/monthly contracts until the remaining time to maturity is less than 2 days. Close the position at the closing price on that day and simultaneously short the next quarterly/monthly contract at the closing price[48] - **Assumptions**: Equal allocation of principal between the spot and futures sides, excluding transaction fees, impact costs, and the indivisibility of futures contracts[48] 2.

Hold the same contract for 8 trading days or until the remaining time to maturity is less than 2 days before selecting a new contract. Even if the result is to hold the original contract, it must still be held for 8 trading days[49] - **Assumptions**: Equal allocation of principal between the spot and futures sides, excluding transaction fees, impact costs, and the indivisibility of futures contracts[49] --- Model Backtesting Results 1.
