Can there be a band in the second period of futures day? In the trend of futures, there are bands in seconds or time periods, but if you want to open positions in seconds or time periods, you should know that the failure rate is very high, because the trend of futures in seconds or time periods is very accidental and random, so the opening error rate will definitely be very large. Why is there randomness and contingency? Because in the futures market, there are settlement transactions every second. Suddenly open more orders, futures will rise. If you suddenly open long and short orders, futures will fall. Therefore, it is very easy to lose money by making orders in seconds or minutes.
