Futures opened at 9: 00 a.m. and closed at 1 1: 30, with an interval of 2 hours and 30 minutes. The significance of setting the 15 minute bar line is:

1, futures are T+0 trading, and the market in the morning is fierce, and investors' trading may be intensive, so 15 minutes is set for two and a half hours. 2. Futures is margin trading, and the risk is relatively greater. If the market is fierce in early trading, a break of 15 minutes will help investors calm down and operate rationally. The middle time from 9: 00 to11:30 is 10: 15, and the rest time of each bar is set to10:15 ~10: 30.

Shanghai Futures Exchange has a lunch break, because its futures are copper, aluminum, zinc, gold, fuel oil and rubber, all of which are metal and energy chemical futures. Daily trading is more active, with a large turnover. The reason why we set a break of 10 minutes every afternoon is also beneficial for investors to judge the disk more calmly and operate rationally. The main reason for setting 10 minutes instead of 15 minutes is that the trading time in the afternoon is short, so it is not appropriate to set a longer rest time. 13: 30 ~ 15: 00 The middle time is 14: 15, and the interval rest time is set to14:10 ~14: 20.
