Look that is fine if you are happy to flounder around and hope you hit on a winning formula then good for you.
But seriously if you want to trade for a living you need to really understand the markets and what is happening when you look at the charts.
Most traders think that all you have to do is watch the candlesticks and their chosen indicators and when this crosses that and overlaps with this and is in the lower or upper level of some indicator then it is time to take the trade. They are doing this relying on some strategy that they have built or been told to use. And most time they lose.
When you learn who and what drives the market then you have a different perspective of how to trade that market.
The market is purely a place where buyers and sellers do business. Contrary to what a lot of traders say and irrespective of the timeframe if someone buys they can only do that if someone sells to them and visa versa. So if you understand who is control of the market and why then you can make a decision to buy or sell and know that you have a strong probability that your trade will be successful.
Buyers and sellers are all looking for the same thing. A FAIR PRICE. So the market will rise and fall as traders look for that fair price. Levels of support and resistance and areas of liquidity where buyers and sellers will have orders. Knowing how buyers and sellers are most likely to react at these levels and being able to read price action at those levels is a great way to trade successfully.
There is far more that is involved than what I have outlined here and the only way to learn more is to find a mentor of a course and do some serious study.
