Usually, the price of futures in the distant month is higher than that in the recent month, because the cost of the distant month should be higher even if only the storage fee is added; If the distant month price is low, it is usually caused by the long-term bearish trend, but once the market comes, the distant month will get the difference back, which is the opportunity of arbitrage; Not all other futures are higher in the distant month than in the recent month. If you look closely, soybean oil was lower than 1009 by several tens of yuan at the beginning of this month, and now the price has exceeded; So once the price of soybean meal rises, the longer you do it, the more profits you get.
