Mean Reversion: Bollinger Bands can also be used to identify mean reversion opportunities. When the price reaches the upper band, it suggests that the market is overextended, and a reversal to the mean (the middle band) is likely to occur. Similarly, when the price reaches the lower band, it indicates an oversold condition, and a reversal back to the mean is anticipated.
ZnWC : Thanks for sharing and I'm impressed by your detailed explanation about TA indicators. I read a post who used TA indicator to explain what he believed and not admit the limitation when a fasle signal appeared. When someone shared an opposite view, he rebutted with remarks like "you don't understand TA". Some analysts use TA indicators to justify their rating but their rating keep changing when the share price fluctuate.
I think TA is a powerful tool but against those who abuse TA to intimidate opposite view. Knowing the limitations of TA is important so that we'll not make mistakes in confirmation bias and you've explained well in your post. Based on study, a stock can remain overbought for a long time in a trending market. TA charts may look 'professional' but it's important to always verify with macro reality and use more than one indicators to check for any false signal.
nerdbull1669 OP ZnWC : Thanks for your comment. I always believe that we need to our due dilligence not only by using TA, things can change anytime. The most important thing is to understand the indicator limitation and choose the multi-indicator that suit the stock. Some indicator does give false signal, how do you identify that? You may look at my other articles where I shared how I use different indicators to assess a stock.
