Explanation to Bollinger's Bands
Bollinger Bands was created by John Bollinger in the early 1980s, which purpose is to provide a relative definition of high and low. This defintion is used to identify buy and sell signals and have 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. Get-A-Graph 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)
Bottlenecks in bandwidth indicates a upcoming change. Break up through the moving average line, or continuously movements above the moving average line indicates a break up, and vice versa downwards.

- 90 day high was $22.85 and low was $18.66.

Amphastar Pharmaceuticals lies in the middle of a wide and weak rising trend in the short term and a further rise within the trend is signaled. Given the current short-term trend, the stock is expected to rise 8.6% during the next 3 months and, with 90% probability hold a price between $21.97 and $25.13 at the end of this period.
Amphastar Pharmaceuticals holds buy signals from both short- and long-term moving averages. In addition, there is a general buy signal from the relation between the two signals where the short-term average is above the long-term average. On corrections down there will be some support from the lines at $21.73 and $21.32. A break down below any of these levels will issue sell signals. A buy signal was issued from a pivot bottom point on Friday September 13, 2019, which indicates further gains until a new top pivot has been found. Some negative signals were issued as well, and these may have some influence on the near short-term development. Volume fell together with the price during the last trading day and this reduces the overall risk as volume should follow the price movements.
