For the same soybean oil variety, the transaction of opening the position first and then closing the position on the same contract day, the handling fee will no longer be halved, and the handling fee standard will be restored to 2.5 yuan/lot. Therefore, when calculating the closing fee, the opening fee and the flat fee should be calculated together. In other words, if your soybean oil futures commission is unilaterally in 3.5 yuan, then the opening commission+closing commission =7 yuan will do.
Because the handling fee of soybean oil futures is charged bilaterally, whether you trade soybean oil futures in the day or not is charged bilaterally.
At present, there is no discount on closing fees for intraday trading of soybean oil futures, but some other futures, such as gold futures, sugar futures and Shanghai copper futures, still enjoy unilateral fee concessions for intraday trading.
