Bollinger Bands
Hello, Let's talk about a great indicator called 'Bollinger Bands.'
On this chart, You'll read what they are, how you can use them, and what the limitations are.
Bollinger Bands are a trading analysis tool developed by John Bollinger. They are used in market finance for technical analyzes and make it possible to assess the volatility and probable evolution of prices or indices. John Bollinger first started using this tool in the 1980s.
Bollinger bands consist of three curves, one curve calculating the moving average of the data over N periods, and two other curves on either side of the moving average, each located in their initial version at a distance of twice the standard deviation over the N periods over which the moving average was calculated.
Initially, N corresponded to 20 days, but we can calculate the bands over other durations. The distance of the bands can also be changed (e.g., 1.5 or 3 times the standard deviation). With a parameter of 2, if we accept the hypothesis of the normal distribution for the values, then 95% of the observed values are statistically located between the two extreme bands.
The bandwidth is a direct indication of the volatility of the asset under consideration. Theoretically, there is more than a 95% chance that the evolution of the value will be established within the framework of the bands adjusted with a distance of two standard deviations. Low volatility is followed by high volatility, and conversely, high volatility is followed by low volatility. As a result, when the spreading of the Bollinger bands is low, it is followed by a substantial spread and, therefore, by high price volatility. These then go up and down with a variable slope.
Some people purchase when the price reaches the lower Bollinger Band and exit when the price reaches MA in the middle of the higher and lower bands. Other traders open short positions when the price cuts over the upper Bollinger Band or sell when the price drops under the lower Bollinger Band. Furthermore, the method of Bollinger Bands is not limited to stock traders; options traders, most reputably referred volatility traders, often trade options when Bollinger Bands are historically far separate or purchase options when the Bollinger Bands are historically tight together, in both cases, assuming volatility to relapse to the standard past volatilization level concerning the stock. Once the bands lie close commonly, a time of low volatility is shown. Conversely, as the bands open, an improvement in price-performance/market volatility is foretold. When the bands have only a slight incline and track almost parallel for a long time, the price will frequently vacillate between the bands as though in a tunnel. Traders are usually inclined to practice Bollinger Bands with other indicators to verify price action. In particular, the advantage of oscillator-like Bollinger Bands will usually be linked with a non-oscillatory indicator-like chart model or a trendline. If these indicators approve the recommendation of the Bollinger Bands, the trader will have higher confidence that the bands are foretelling accurate price action about market buoyancy.
- If the bands squeeze during a phase of low volatility, it increases the possibility of a visible price move in either direction. This may begin a trending movement. Mind out for a false move in the reverse direction, which changes before the proper trend starts.
- When a considerable amount separates the bands, volatility increases, and any existing trend may be ending.
- Prices manage to bounce inside the bands' box, reaching one band then moving to the other. You can use these rhythms to identify possible profit targets. For instance, if a price bound off the lower band and crosses over the MA, the upper band matches the profit point.
- Value can pass or touch a bandbox for increased periods through firm trends. On alteration with a forced oscillator, you might need to do extra analysis to decide if taking additional profits is suitable for you.
- A powerful trend continuation can be assumed when the price moves outside of the bands. Nevertheless, if prices move instantly back inside the band, then the recommended strength is canceled.
Bollinger Bands can be applied to discover how well an asset is growing and when it is probably turning or losing potency. If an uptrend is big enough, it will reach the upper band constantly. An uptrend that gets the upper band shows that the stock is selling higher, and traders can utilize the chance to make a buy choice. If the value draws back within the uptrends and lingers above the middle band and moves backward to the upper band, that determines a lot of strength. Frequently, a price in the uptrend should not reach the lower band, and if it does, it is a caution sign for the opposite or that the stock is dropping strength.
Most professional traders try to benefit from the powerful uptrends before a reversal happens. Once a stock loses to touch a new height, traders manage to trade the asset at this point to avoid acquiring losses from an inverted trend. Professional traders observe the performance of an uptrend to know when it shows power or weakness, and they apply this as an implication of a potential trend refusal.
Bollinger Bands can decide how well an asset is dropping and when it is likely turning to an upside trend. In a pronounced downtrend, the price will move on with the lower band, which explains that selling action remains powerful. But if the price collapses to reach or move along the lower band, it is a sign that the downtrend may be losing force. When there are price pullbacks, and the price lingers under the middle band and then goes back to the lower band, it means a lot of downtrend pressure. In a downtrend, prices should not break over the upper band since this would suggest that the trend may be changing or decreasing.
Many traders avoid buying through downtrends, other than looking for a chance to buy when the trend reverses. The downtrend can remain for short or long durations – minutes to months or even years. Investors must recognize any indication of downtrends quickly enough to protect their investments. If the lower bands display a constant downtrend, traders must avoid opening into long trades that show unprofitable.
Trading W-Bottoms and M-Tops:
W-Bottoms and M-Tops identified 16 models with a fundamental W-Pattern and M-Pattern. Bollinger Bands apply W patterns to classify W-Bottoms when the other low is cheaper than the first low but continues over the lower band. It happens when a low response forms near to or under the lower band. The price then tends back towards the middle or higher and builds a new low price that stays the lower.
Limitations of Bollinger Bands:
Although Bollinger Bands are practical tools for professional traders, traders should analyze a few limitations before applying them. One of these conditions is that Bollinger Bands are fundamentally reactive, not predictive. The bands will respond to changes in price movements, either uptrends or downtrends, but will not foretell prices. Like most professional indicators, Bollinger Bands are a lagging indicator. Although businesspeople may use the bands to measure the trends, they cannot apply the tool alone to make price forecasts. John Bollinger suggests that traders use two or three non-correlated tools that give more literal market signals.
Another limitation is that the official settings will not operate for all traders. Traders need to discover settings that let them set guidelines for particular stocks that they are purchasing. If the chosen band settings fail to work, traders may change or use another tool entirely. The effectiveness of Bollinger Bands changes from one market to another, and traders may be required to modify the settings if they are trading equal protection over some time.

I used some sentences from Wikipedia and BollingerBands since they were explained in the best possible way for you guys to understand.
Good Luck
