Most of the traders are generally aware of the basic concepts on Bollinger bands, such as the price action tending t follow a band until a reversal, which then targets the other band. But Bollinger bands don’t end up to this much, they are more than this. Here you will be presented with those concepts through which you can have insights on how to interpret the chart.
People will tell you to expect when the price reverses from the upper band it will continue down until it touches the lower band but though there is some variation in the decline at the centerline and this may also be the factor supporting for another uptrend. That’s why it is better for you not to ignore the center line of the brands.
When in an uptrend, it is expected to the price to remain between the centerline and upper band. If the price falls below the center line, it tells you about the increment in weakness, and you should look for the trend to change. Similarly, just the opposite of the uptrend, if in a downtrend the price rises above the center line this shows some strength returning to the stock, and interesting action ahead.
You become able to deduct the future price actions by monitoring the reaction of the band to an impending price. While it is helpful to have other indicators as confirmation, you’ll find that the majority of the time, the chart will keep on continuing as following:-
If the price climbs towards the upper band and in response the band heads further up, then you can reasonably ponder upon that the uptrend will keep on continuing and the price keep hitting higher highs, forming the classic Bollinger band chart. Nevertheless, if the price rises in an uptrend but the upper band reacts by flattening down to run horizontally, you can expect that the price may touch or just penetrate the band, but will then reverse. Sometimes the reversal will not be wrong, and the band will start moving back upwards, which may indicate that the price will move back to the upward trend.
When if the price is falling, one of two situations may apply. In the case of rushing down of the lower band, this gives an idea that the bearish trend has taken hold, and you can expect successive lower lows. On the other hand, if the falling price rushes towards a lower band which comes up to the horizontal, this will likely be a setback point, and the start of an uptrend. The same caution is relevant to this as to the previous case. If you find that the uptrend is only progressing weakly, and meantime the low band starts to go back downward, then the bears have won and the downtrend will take hold again.
Because of the limitation in the Bollinger bands, a pressure would be formed attempting the price to break out, either upward or downtrend. While the bands provide good support and resistance levels, it is worth having a glance through these against other natural support and resistance boundaries.
