1, immediate profit refers to about half an hour after the opening of futures. If there is no speculative profit within half an hour, it may be that the position direction is different from the real trend, and the adjustment of futures prices will not exceed half an hour. In the short-term operation of futures contracts, investors may not be able to complete the opening operation when the futures price starts to adjust, so in actual transactions, there is no profit after holding positions for half an hour, and short-term losses occur. There is no limit to the profit margin. It is a good investment curve, and there is no strict limit on the profit rate. However, in actual combat, with the clear trend of futures prices, the profits gained by speculators are gradually expanding. Of course, we should also pay attention to the operation of taking profit and going out. The fluctuation direction of intraday futures price can be one-way or two-way frequent fluctuation. It should be noted that frequent and excessive trading can only be given to speculators.
