Yes, but not as accurately as would make me wealthy.
I can see the charts, but making the proper entry and exit is a much more difficult task. Also, you have to deal with the market makers who are frontrunning your orders.
The way I lost a lot of money was when COMEX decided to raise margin rates on the contracts I was holding, forcing me to liquidate at a huge loss.
So, when you are in the organized markets, you are at the mercy of too many people and organizations whose only job is to take your money.
