Do short-term according to the changes in the disk, so as to buy better, which can also be a good chasing skill. The short-term operation of KDJ indicator is that its value should be set to 9, 3 and 3. The short-term skills of KDJ summarized by the author are introduced as follows.

First look at the 60-minute short-term indicator. The main thing here is to observe whether the values of KDJ begin to cross at 20 o'clock. If there is a cross, then investors should go to the second step, that is, to see whether the 20-day and 30-day moving averages of the 5-minute K-line are flat or slightly upturned below the half-year line. If the stock suddenly drops in volume at this time, and the upward trend of the 20 th and 30 th moving averages remains unchanged, investors can boldly buy. Of course, if the 20-day and 360-day moving averages turn flat around the half-year line and go up slightly, you can buy them.

So, as a short-term indicator, how does KDJ decide to sell? When the value of KDJ reaches above 80.90, if the J-line peaks and the stock price suddenly rises sharply within 5 minutes, it is a good time to sell in the short term. If you miss it, you have to vote for the third 5 minutes. Sometimes the second 5-minute high is higher than the first sudden high.

Look at the five-minute line. Generally, it doesn't suddenly increase a lot, but it is moderately aggravated. If this happens, see if the time-sharing moving average is still in the upward direction. If the shape slows down and becomes flat, throw it away immediately. Of course, in the end, we should judge it according to the market trend.
