How do I pick stocks with the boll indicator of Tom Tom? It is to find: the closing price in the boll line above the stock, please expert guidance!

The Bollinger Bands indicator was originally an oscillator indicator to be used with the Bollinger Limits, Limit Wide, and these two indicators **** together. The latter two are used to identify false signals as well as change signals.

1. When the price rises across the upper Bollinger Bands, the chance of a retracement is high;

2. When the price falls across the lower Bollinger Bands, the chance of a rebound is high;

3. When the Bollinger Bands become narrower, it means that a change in the market is imminent;

This is a more traditional use of the Bollinger Bands.

I suggest not using him as a shock indicator, because its value is much more than that, and it is actually higher to use it to catch the signal of a market change.

The narrowing of Bollinger Bands often signals the end of a previous trend (whether it was previously an oscillator or a one-way trend).

If the Bollinger Bands get narrower for a long period of time, it often means a big move. If used for stock picking, this is basically a tried-and-true good signal.

The length of this time period, thought the magnitude of the narrowing of the Bollinger Bands, can be quantified using the extreme width indicator.

The most obvious example is Shandong Haihua during this period, you can see how long it has been trading sideways, and by late February, the Bollinger Bands were already so narrow that its limit width index reached 0.04, which is unheard of in the history of the stock.

But it's important to note that this kind of signal only tells you that there's a big market ahead, but whether the direction is up or down is something that needs to be judged by other parties.
