When the signal line of the RSI indicator falls below 30, the asset is 'oversold,' meaning it can start the uptrend in the nearest future. The idea of this indicator was to combine trend strategies with volatility and oscillator indicators. The bands are indicating the current price direction taking into account the current price volatility.

Bollinger Bands work best when the middle band is chosen to reflect the intermediate-term trend, so that trend information is combined with relative price level data. To calculate bands, you should first identify a simple moving average. Secondly, you need to add or subtract a specified number of standard deviations from the simple moving average.

In a downtrend, costs shouldn’t break over the upper band since this would demonstrate that the trend might be switching.

Information on both was hard to obtain in those days but I persisted; with the help of an early microcomputer I was able to make some progress. At the time we used percentage bands and compared price action within the bands to the action of supply/demand tools like David Bostian's Intraday Intensity. A touch of the upper band by price that was not confirmed by strength in the oscillator was a sell setup and a similarly unconfirmed tag of the lower band was a buy setup. If you were bullish, you had a natural tendency to draw the bands so they presented a bullish picture, if you were bearish the natural result was a picture with a bearish bias.

There are two main signals in this strategy that you should always keep in mind. The best way to find the entry point is to look at the position of the price in relation to the lower band. Once they meet, you can exit the market and look for other opportunities.

Bollinger bands are commonly used as a “reversion to the mean” indicator. If price is below the Bollinger bands, it might be taken as an indication that price is currently too low. Likewise, if the price is above the bands, price may be interpreted as being too high.

The author of the indicator looked for an effective way to select the interval for a long time. The very first mention of a tool similar to Bollinger Bands dates back to 1960.

But take a look at how slow it was in showing the trend change. By default, the overlay uses a 20-period SMA and sets the bands 2.0 standard deviations above or below the SMA. These parameters can be adjusted to meet your technical analysis needs.

Since the SMA is essentially an average and the price keeps swinging from one side of the SMA to the other, you are bound to end up with a profit. This strategy can also be used in times of very low volatility. Bollinger bands help us to understand the volatility of an asset.

Then after a while, another low is established, and this time it is above the lower band. The standard deviation measures how spread out numbers are from an average value for a given data set. The variance itself is the average of the squared differences of the mean . It is a mathematical measurement of average variance and appears prominently in economics, statistics, finance, and accounting.

When that happens, a cross below the 20-day moving average warns of a trend reversal to the downside. A stock may trade for long periods in a trend, albeit with some volatility from time to time. To better see the trend, traders use the moving average to filter the price action.
