Uninvited.

Bollinger Bands are occasionally used in my trading system. In this case, let me briefly explain the use of Bollinger Bands.

Bollinger Bands are also called Bollinger Bands. We shrink the K-line to a very small size, and we can clearly see that the K-line generally runs within the Bollinger Bands.

Then using Bollinger Bands, you can clearly and intuitively see the running status of the market K-line. For example, Brin opened his mouth: A big market trend has just begun. Bollinger closed his mouth; the market entered a state of terminal shock. Bollinger Bands is sideways: the K-line is in a oscillating state.

This is a relatively intuitive content that can be seen. To be more detailed, Mr. Bollinger has three lines, which divide the market into four spaces. I generally think that from top to bottom, they are: super strong area, strong area, weak area, and extremely weak area (this is my Your own division may not be found in the book)

The line in the middle of Bollinger Bands is actually the cost moving average. We generally see that Bollinger Bands have two parameters (20, 2), and the default is In this way, the middle track is actually the 20-day cost moving average, and parameter 2 is used to adjust the channel width. Generally speaking, the smaller the previous parameter is, the more complex the trajectory of Bollinger Bands will be. It will open and close very frequently, and the effect of the support pressure provided by the three lines will not be particularly obvious. The parameters I personally use are (100,2), as shown in the picture. This kind of Bollinger Band looks wider and will not close or open easily, and the support pressure effect provided by each line of the channel will be more obvious.

In addition, what else should I look at when looking at Bollinger Bands? In fact, the three lines of Bollinger Bands often provide some pressure support levels that cannot be seen by other indicators. For example, when the market is in a long-term divergence operation, at this time, the moving average is generally below the K line, and it is difficult for you to predict the pressure on the market. Where is the point? If you adjust the market to a large cycle at this time, you can find obvious pressure positions from Bollinger's upper and middle tracks.

The usage method actually revolves around these three lines. For example, when the market breaks through the middle track of the Bollinger Bands from the weak range, if the K-line is confirmed multiple times on the middle track of the Bollinger Bands and still does not break, then the market is likely to reverse from a short trend to a long trend, and vice versa. In addition, when the channel fluctuates sideways, Bollinger Bands have a miraculous effect in making the market fluctuate.

Here is an example of the Japanese yen’s 4h, the K-line strongly broke through the Bollinger Middle Track, and the market turned from bullish to bearish. The entry position generally revolves around these three lines. I won’t go into too much detail, and I can’t finish it here. The poster can use the historical disk to find more patterns and summarize it himself, and he will gradually understand it.
