Methods vary from person to person.
But generally look at the short-term K-line chart, which can be one minute, three minutes or five minutes.
You can read technical books.
For example, you can make a rectangle with high throwing and low sucking, or you can find a big trend to make a golden fork.
But what kind of market is suitable for sorting out shocks, and what kind of market is easy to form unilaterally?
No one can tell you this, because it depends on experience, not words.
But what I want to say is that no matter who you are, you must strictly carry out stop-loss and profit-taking, especially ultra-short-term ones. It is also important to grasp the position.
In addition, if you are doing ultra-short-term, then you should look at it from a short-term perspective, and don't add fundamentals, which is often not good.
Finally, before doing it, do more simulations to find out the feeling. It is impossible to succeed without a period of training. It is best to use less money to touch futures first, and then try to make big money in a few years. If you want to make a lot of money from the start. That's no different from gambling.
All the above are my own little experiences, for reference only.
