Some of these technical analysis tend to work well when a particular market is already following a particular trend, it is easier to interpret, but crypto sometimes can be funny when all indicators may be shown an uptrend or buy signal and all of a sudden the unthinkable happens and obviously it is not related to any known fundamental. I employ all those but always have a stop loss in case market goes otherwise
Well, what is the point of technical analysis if it is not all about the trend in the first place? As long as trading is concerned, trend is always the first thing to look at most of the time, and there is absolutely no way you can do well without at least knowing how to monitor trend.
This is where the whole idea of TA and trading strategy comes in. Your strategy is dependent on your use of these indicators and market trend analysis to know how you want to be approaching the market, but there are other things that also apply to trading, such as risk management, principle and discipline and a lot of other things, which if you do not have, you may still find it hard to trade effectively.
