I am trying to learn more about trading strategies specially in Technical Analysis. Upon trying different indicators, it comes to my mind that indicators might become an obsolete one day.
No
Just imagine if all of us knows how to use RSI and MACD. We all know when it is overbought or oversold. Therefore, we already know as well when it is good to enter and exit in market. Since we all knew about, RSI is not a good indicator anymore and many of us will find a new indicator that will provide us more details than the latter one.
If using indicators alone without the right strategy, losses is more possible. There are times too that indicators will fail. No matter how good a trader is, trading analysis can not 100% be accurate all the time.
Now, many Trading Gurus are teaching the best strategy to use. Wherein fact, strategies are becoming obsolete as time goes by. If you are new in trading world, definitely you will be eaten by those traders who know a lot in trading.
This is just it, if you are good in anything, you will make money. In trading, those that do not yet know about ways to make money from trading, they will lose to those experienced traders to gain, but this does not mean that experienced traders are not losing at times.
