As a trader in this field of crypto trading, I know that not all indicators used by some traders are accurate because there are other tools out there that don't give a profit to some traders in reality. And that is because the understanding is not correct or the other indicators are not all accurate, and BB is one of them.
Yes. But let me make it correct for you. All indicators are not accurate.
It may be effective for others or you, but I am pretty sure that most of us traders are not using an effective strategy because, if they look at the BB, it is very complicated to read. Unlike RSI and MA, Trendline is easy to understand.
BB is not complicated to read. When the market increase and the candle touch the upper band, it means overbought market. Which means the market might reverse soon. Same goes to the lower band when the market price of a coin is falling. Very deceiving if you start trading you will know. The problem is that to use indicator to earn money from trading, you need to have experience. Also you need to use other indicators. I also like RSI. I like SAR and many others, but they can all also fail. The reason we need strategies to help when the indicators fail.
