Dải Bollinger (BB) là một công cụ phân tích kỹ thuật phổ biến rộng rãi được tạo ra bởi John Bollinger vào đầu những năm 1980. Dải Bollinger bao gồm một dải có ba đường được vẽ ra liên quan đến giá chứng khoán. Đường ở giữa thường là Đường Trung bình trượt Đơn giản (Simple Moving Average - SMA) được thiết lập trong thời gian 20 ngày (nhà giao dịch có thể thay đổi loại đường xu hướng và khoảng thời gian, tuy nhiên đường trung bình trượt 20 ngày là phổ biến nhất). Khi đó đường SMA đóng vai trò là Dải trên và Dải dưới và được sử dụng để đo sự biến động bằng cách quan sát mối quan hệ giữa các Dải và giá. Thông thường Dải trên và Dải dưới được thiết lập theo hai độ lệch chuẩn so với đường SMA (Đường giữa Middle Line); tuy nhiên nhà giao dịch cũng có thể điều chỉnh số lượng độ lệch chuẩn này.

Hey guys,
Ive been thinking about Price Volume Trend for a while and tried adding different moving averages to it, but seems its not as binary.
Therefore adding the bollinger bands as a no-trade-zone made it alot better. Indicator is pretty basic at the moment since I just implemented the idea but im planning to do some add-ons later on to make it easier to read....
This is just a Bollinger band indicator that uses the highs & lows in addition to the close in the calculation of volatility / deviations from average. These bands will be slightly wider than regular Bollingers as a result.
I've found it useful with very short lookback lengths (3 to 5) for identifying periods when the bands are contracted... usually leads to an...
Bollinger Bands coloured to more clearly show periods of contraction and expansion. Green filled bands indicate expansion/increasing bandwidth, and red fill indicates contraction/decreasing bandwidth.
This is my thank you to the TradingView community, for the people who are sharing their scripts, which allowed me to learn Pine Script.
So here is my first creation, feel free to experiment, modify and use it as you wish.

The Volatility Combo Bands are made from 4 separate volatility bands- two Bollinger Bands (10 and 20 period) and two Price Headley Acceleration Bands (10 and 20 period). The Volatility Combo Bands plot the innermost upper and lower points from these bands and then plots a mid-line. By default, only the standard 20 period Bollinger Bands and Combo Bands with...

In fact, I wrote this script for detect Bollinger and Linear Regression Bands squeeze.
It's a side script.
Logic works like this:
Only the stagnant market probability is drawn from the Bollinger bandwidth by Dependent Variable Odd Generator and MFI index is calculated taking into account the volume.
This value ranges from 0 to 100.
To be sure, this value is...

This is a different type of bands. I modified Alex Pierrefeu Recursive Bands algo. It is a smoothed version of Alex's algo and imo it suites better for heikin ashi candles but it works well with regular candles.
How to use it:
When price hugs the upper band. It is a potential long and when price hugs the lower band it is a potential short.
Credits to Alex...
On fundamentally strong stocks for entry points. The area in the Gray lines is the best one to enter and reasonable valuation. The area in the Red lines indicates higher Valuation. The area in the Green lines indicates lower Valuation and better to be careful and avoid.
