Is Bitcoin overbought or oversold? Use Bollinger Bands to find out!

Let’s learn three simple methods to use this indicator in trading.

what are bollinger bands?

John Bollinger created and copyrighted Bollinger Bands in the 1980s. The indicator consists of a middle band, which is a simple moving average whose default value is set to 20 periods, and two outer bands set two standard deviations below and above the mean band.

Its most basic use is to identify whether the price is high or low on a relative basis. If the price is above the upper band, the asset is perceived to be overbought. On the other hand, if the price dips below the lower band, the coin is believed to be oversold.

However, many traders make the mistake of assuming that the price of the asset will fall when it reaches the upper band, or that a rally will start when the price reaches the lower band.

This usually only happens when price is stuck in a range. As with any indicator, assumptions can easily lead to big losses in a trending market, so looking for the confluence of a number of metrics is still good practice.

let’s look at some ways traders use bollinger bands.

bollinger bands can detect volatility pressures

according to john bollinger, assets switch between phases of low volatility and high volatility. therefore, after periods of low volatility, traders can expect volatility to spike, which could result in trending movements.

The above chart shows how the overly eager bulls and bears can become trapped. On Oct. 22, 2020, the bulls pushed the price above the upper band but could not clear the resistance at $5.77.

classic ethereum (etc.) broke above $5.77 on Nov 1st. 18, 2020, but it was not a perfect trade as the price did not start a strong uptrend. the market makers were chasing the stops from the buyers and also tried to catch the bears with the sharp drop on December 1st. January 23, 2020.

However, the price quickly climbed back above the lower band on December 12th. 24, 2020, and the etc/usdt pair soon started a strong bullish move.

hence, instead of relying solely on the bollinger bands signal, traders should also look for confirmation from other supportive indicators or use support and resistance lines.

bollinger bands can signal when to buy during a pullback

A pullback in an uptrend is often a buying opportunity as the main trend tends to reassert itself. When the middle band is sloping up and the price is trading in the area between the middle band and the upper band, it is a bullish trend signal. In this scenario, traders can wait for the bounce off the middle band to initiate long positions.

There are several possible entry opportunities and a trader would wait for the price to close between the upper bands for three consecutive days before buying, because this can help avoid unforeseen swings.

traders can keep the initial stop-loss below the middle band, but raise it quickly to reduce risk and protect profits. one of the possible exit strategies would be to sell on a close below the upper band of bollinger bands with one standard deviation.
