BOLL indicator practical skills: buying and selling signals and key points for judging holdings and currency holdings

The practical skills of the BOLL indicator are mainly reflected in the position relationship between the stock price K-line (or US line) and the upper, middle, and lower tracks of the indicator, as well as the changes in the opening and closing of the Bollinger Bands. In some market software, the BOLL indicator is displayed on the main chart by default. If you want to more accurately analyze the market, you can combine the BOLL indicator with the TRIX indicator. Below isKCM ForexTaking the BOLL indicator in common market terminals as an example, illustrate its buying and watching functions. (Note: In most software, the parameters of BOLL indicators are generally not modified). 1、 Buying and selling signals

1. When the K-line of the stock price breaks through the upper limit of the Bollinger Bands and the TRIX indicator has formed a "golden cross" at a low level, it indicates that the stock price is about to enter a medium to long term upward channel, which is a buy signal issued by the BOLL indicator. At this point, investors can consider buying in a timely manner.

2. After a long period of narrow horizontal movement at the low level of the Bollinger Bands, once the K-line of the stock price breaks through the upper limit of the Bollinger Bands and the originally narrow Bollinger Bands channel suddenly opens up, it indicates that the stock price is about to leave the original horizontal operating channel and enter a new upward channel, which is also a buy signal issued by the BOLL indicator.

3. When the K-line of the stock price breaks through the middle of the Bollinger Bands and the TRIX indicator has formed a "death cross" at a high level, it indicates that the stock price is about to enter a medium to long term downward channel. This is the sell signal issued by the BOLL indicator. At this point, investors should clear their positions and leave the market as soon as possible.

4. After a long period of narrow horizontal movement at the high level of the Bollinger Bands, once the stock price K-line breaks through the lower limit of the Bollinger Bands and the originally narrow Bollinger Bands channel suddenly opens downwards, it indicates that the stock price is about to leave the original horizontal operating channel and enter a new downward channel. This is also the sell signal issued by the BOLL indicator.

2、 Stock holding signal

1. When the Bollinger Bands open upwards, as long as the K-line of the stock price remains above the middle track of the Bollinger Bands, it indicates that the stock price has been on a medium to long term upward trend, which is a holding signal sent by the BOLL indicator; If the TRIX indicator also sends a holding signal, this signal will be more accurate. At this point, investors can patiently hold onto their stocks and wait for an increase.

2. When the Bollinger Bands open downwards, as long as the K-line of the stock price remains below the middle track of the Bollinger Bands, it indicates that the stock price has been in a medium to long-term downward trend, which is a holding signal issued by the BOLL indicator; If the TRIX indicator also sends a holding signal, this signal will be more accurate. At this time, when observing changes in indicators on KCM forex and other market software, it is advisable to remain patient and hold onto the currency to observe.
