Advise Appreciated

I (24M) have put in about 20k so far in the stock market and it is currently valued at ~17k.
I work currently with decent salary.

I have realised my mistake viz I am not doing enough research.

I am thinking of making profits via swing trade as I don’t understand F&O.

I need Advise on how to identify chart patterns and what would be a genuine place to learn the same.

I would also request that you guys help me with different platforms to research.

I have the premium subscription of ET, also give opinion if it is an investment or not.
