technical analysis is a useful tool for traders, but we have to consider it's limitations. Technical analysis is basically based on assumption about the past market statistics and data, without putting into consideration other external factors . So traders should not 100 percent rely on technical analysis, they should use it together with other methods of analysis.
Some of its limitations includes
1.it is based on assumptions about past market trends, gotten from the past market price and volume data
2.it is a backward tool subject to interpretation from different traders.
3.Technical analysis will not provide the full details of the market, that is putting economic and global events into consideration,
so traders should put all these factors into consideration before making an investment decisions using technical analysis.
As long as predicting the market is concerned, nothing can ever be relied on to work at 100 percent accuracy, if there was, don't you think we all did be rich by now, do you really think that professional traders will still sometimes trade at a loss? Of course not.
Technical of fundamental analysis (as the case maybe) is just a tool that helps traders and investors to make better predictions, remember the key word here is
Predictions, which in other words, can be referred to speculation, which also means that it's something that is assumed to happen which one is not very sure of or certain about.
So, yeah, technical analysis is not a one way ticket to trading without loses, if it was, we all did be rich, yeah?, yeah, I think so.
