Explanation to Bollinger's Bands

Bollinger Bands was created by John Bollinger in the early 1980s, its purpose is to define price action relative to the assets highs and lows. This technical indicator is used to identify buy and sell signals and has proven very well in doing so.

Bollinger Bands consist of a set of three curves drawn in relation to securities prices. The middle band is a measure of the intermediate-term trend, usually a simple moving average, that serves as the base for the upper and lower bands. The interval between the upper and lower bands and the middle band is determined by volatility, typically the standard deviation of the same data that were used for the average. StockInvest.us uses Bollingers suggested 20 day average.

Middle Bollinger Band = 20-period simple moving average
Upper Bollinger Band = Middle Bollinger Band + 2 * 20-period standard deviation
Lower Bollinger Band = Middle Bollinger Band - 2 * 20-period standard deviation

BandWidth defines the current width of the band.
%b defines the current position within the band.

BandWidth = (Upper Bollinger Band - Lower Bollinger Band) / Middle Bollinger Band
%b = (Last - Lower Bollinger Band) / (Upper Bollinger Band - Lower Bollinger Band)

Bollinger Bottleneck Buy Pattern 2

Bottlenecks in bandwidth indicate an upcoming change. Break up through the moving average line or continuous movements above the moving average line indicate a break up, and vice versa.

STAA Signals & Forecast

The STAAR Surgical Company stock holds a sell signal from the short-term Moving Average; at the same time, however, there is a buy signal from the long-term average. Since the short-term average is above the long-term average there is a general buy signal in the stock giving a positive forecast for the stock. On further gains, the stock will meet resistance from the short-term Moving Average at approximately $46.95. On a fall, the stock will find some support from the long-term average at approximately $41.46. A break-up through the short-term average will send a buy signal, whereas a breakdown through the long-term average will send a sell signal. Furthermore, there is a buy signal from the 3 month Moving Average Convergence Divergence (MACD). Volume fell during the last trading day despite gaining prices. This causes a divergence between volume and price and it may be an early warning. The stock should be watched closely. Some negative signals were issued as well, and these may have some influence on the near short-term development. A sell signal was issued from a pivot top point on Tuesday, April 09, 2024, and so far it has fallen -10.91%. Further fall is indicated until a new bottom pivot has been found.
