It's true that what you say is that there are no 100% accurate predictions, it's just that perhaps by predicting them we can understand a little of the developments that are occurring.
-cut-Same in the case here, but the technical analysis of the people are so strong the in the trading not all but some of the traders who have studies the coins and they have even all the information about the graphs of the coins. But still the may fail at some points due to the market up and down. So I didn't fully believed in these things like following them on different occasions.
Yes I agree with that, as I said no prediction is 100% accurate.
In fact, predictions always involve uncertainty (speculation), but having experience and knowledge can help us manage risk. Although technical analysis can be powerful, market fluctuations remain a factor that is difficult to fully predict.
For the fact that nothing is perfect doesn't mean that we should not have our preferences, and for trading analytical concerns, my preference over and over again is technical analysis, no other analytical type can be able to contend with it. But the issue is that people expect more from it or are using it wrongly, so they expect it to deliver that signal as if it's a wizard. But it's not so, it's an analytical means which can only be predictive in nature, and of course, predictions are not prophecies, so it's those people looking for more from what it was coded to do that should have a rethink.
And I say this without apology, to know the true sentiment of the market, you need the technical analysis and make sure you follow the trend it tells you, not otherwise. But some people go for the retracement and reversal of the market rather than the trend which denotes the sentiment of the market. They will then blame the analytical style for their woes, while some use some wrong timeframes as well, especially the lower ones and expect the best from it.
