I have encountered this kind of problem, which is related to the short cycle. Some domestic futures products follow the broader market to some extent. Recently, the market rebounded and oscillated, which led to many domestic futures varieties rebounding and oscillating under the general downward trend. This market is not suitable for operation.

In most cases, the 5-minute line will run in reverse all day after jumping in the morning. You can enlarge the cycle, do a 30-minute trend, and find the starting point from 5 minutes. If the market trend is unknown, you should close your position and avoid overnight orders.

In the short term, most cases will be reversed. Support and resistance levels are very different from those of stocks.

Breakthroughs of different varieties must be cautious. For example, rebar will break through 2-3 basis points, but most of them are false breakthroughs.

Unfortunately, the empty order of corn was tied at the end of yesterday. I think the external market will be stronger last night, and the market may open higher. As a result, corn opened lower today. It is a big mistake to lose the correct position.
