How can it be overrated ? Everything in trading depends on candlesticks. By looking at the candlestick charts, you can determine when it is good to invest or when it is bad. How would we get the signals if there was no candlestick? I think this question has no logic because trading analysis fully depending on candle stick . So I can't agree with that it's overrated.
One thing some traders does not know is that the market can not be easily traded using one pattern which can bring losses. When I started trading I learnt the candle stick pattern but I still get confused of the market when I will want to put my candle stick knowledge in use. Nothing works in isolation so we just need to couple everything about trading in one use.
Candle stick pattern can be combined to indicators to get some good understanding about what could be the possible movement of the market. All these work hand in hand to get the best results from the market since multiple tools is what could give us a better possible direction of the market.
Sooner or later they would really realize those things on which if they do tend to engage with trading then those patterns would really be helpful specially if you do know on how to understand it.
They arent overrated but rather its mainly needed because you would really be having the idea on what to do if you do know on how to read up candle patterns.You cant just make out outright decision
in related into your trading position if you dont even consider on what it is forming although its not really that a reliable thing most of the time but it is really better compared when you arent
using something and just like on what others been saying above that it is really useful and you would find it for it to be mainly needed.
