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.
Are you f**king kidding me? Or do you really know what technical analysis entails? If you where talking of technical indicators, that would have been understandable because I have also gotten a fare share of my own experience with technical indicators, which only shows you what has happened in the market in the past, but not what's going to happen in the future, so if you really want to be successful in trading, using only the analysis of technical indicators to trade is a total failure.
So as a trader , it's very important you to know what technical analysis entails, because technical analysis is the overall forecasting of the market, and what is expected next of it, if forecasting is the right word to use, so if you are very good at doing technical analysis in trading, their is a very high possibilities of you being profitable, if you can manage your risk properly.
I doubt TA is the overall forecast of the market, its only a bais showing how traders should react to the market, Fundamentals are needed and Fundamentals have more impact on the market especially in FX market, but in crypto Fundamentals have less impact.
I agree with you that a good Technical Analyst have very high possibility being a profitable trader as far he knows and have an edge.
I don't buy the idea of using Technical indicators, as its misleading and doesn't show the knowledge or idea of a trader at all. Some Traders can't trade, they don't know anything about structure, or how the market react but know all types of MA, MACD, to mention but a few because I don't use indicators. Though we have leading and lagging indicators.
In essence do what works for you, we only react based on whatever our strategy is, as far we are getting paid leverage on what is working for you.
