The market situation is ups and downs. If you play short-term and short-term arbitrage, you may think that you should only buy in one direction and not carry out both long and short positions. This will make your system thinking more complicated. Think about it from the perspective of mental psychology. Our brains have built-in Complex, more is less, complexity is simplicity. From a human perspective, the brain should be adapted to simple operations and performed according to a rule, so that it can better adapt to life.

In this way, the "Tao" comes, which is what is often called the system. If you follow your own trading system, you will earn stable profits, so make your trading simple. If you follow the rules and do things, you can often earn stable and long-term income. Life is like a journey against the odds, and I am also a traveler.
