The answer first: you can
Search this question and nine out of ten results are broker pages. Their answer is consistent: yes, you can learn on your own — come and open an account.
That is true. It is just not the whole answer — because what they sell is the account, not the teaching.
We sell the teaching. So by rights we should be telling you no, you need someone.
But the honest answer is: you can learn on your own. Nobody is born unable to read a chart.
Candles, direction, momentum — all three are things you can see. The material is out there. Put in the time and you will learn it.
This part is not the hard part.
