Futures are affected by many factors. If you can correctly predict the trend of a certain variety in the futures market, then you can make money from it. But the futures market is changing rapidly, and no one can predict it 100% accurately. It is very remarkable to be able to continuously improve the correct probability of your prediction.
Personally, the highest realm of futures trading is the combination of man and sword, that is, you can easily master the futures market and make a profit as long as you take a shot.
