If the futures price was low at that time, the strategy of buying long months could improve the odds in some cases. This is because the premium of futures contracts that rise in distant months is usually higher than those that rise in recent months, so it can reduce the transaction cost and the risk of market fluctuation and improve the profit probability. However, when choosing a long-term hedging strategy, we need to consider the appropriate time and price, and at the same time, we need to carry out risk management and position adjustment according to market trends and fundamentals. For example, if the spot price falls, the futures price of a subject matter may also fall, and some factors that may affect the price need to be carefully studied and predicted, so it is necessary to adopt a long-term buying strategy.
