You said that the floating profit decreased because the floating profit after opening the position on the same day was calculated according to the latest price and opening price, while overnight, the calculation method was calculated according to the latest price and yesterday's settlement price. Because the opening price was higher than the closing price, the floating profit decreased the next day. You say that the time-sharing trend is low and the daily K-line is high because the settlement method of futures is different from that of stocks. If the stock is high the next day, regardless of the time-sharing trend or K-line, it is compared with the closing price of the previous trading day. In futures, the closing price of K-line is clear at a glance, but the time-sharing chart involves a settlement price, and yesterday's closing price is far from the settlement price, so the opening price of the day will be just above yesterday's closing price and below the settlement price. You will often see this situation in the future.
