How many minutes is it best to watch the K-line of short-term futures trading? Why?

Each investor's operating system and operating mode are different, and the analysis of different operating modes is completely different, which also includes the choice of analysis cycle.

If an investor is making a trend, he is unlikely to see a short-term K-line chart, such as 1 minute K-line chart or 3-minute K-line chart. It is useless to do short-term intraday trading and look at a long-term K-chart. Do short-term in the day, watch short-term K line, 5 minutes, 3 minutes, 1 minute. When the price reaches the expected high or low point, it is best to combine the K-line analysis of 15 minutes or 30 minutes.

There is no need to watch the long-term K-line just for short-term hype. When the signal appears, the price may have risen or fallen by a certain extent, and the signal will inevitably lag behind. Short-term K-line can be very sensitive to the direction of price fluctuation, but the disadvantage is that there are too many signals, which requires investors to master the filtering ability of signal interference. Its advantage is that it will not miss the opportunity to judge according to the short-term K-line signal. Once the long-term K-line price forms a certain trend, its prompt is very stable, which can help investors grasp the good opportunities in large bands, but there is nothing they can do about small-scale fluctuations.

So, you need to determine what cycle you want to operate first. I don't think you will think about doing the sun for a while and doing the trend for a while. What matters is not what cycle is good, but finding the operation that suits you.
