Futures trading ultimately pursues simplicity. To be precise, it is simple to the core. If not, the foundation is unstable, the market is complex enough, and you are complex, you will be possessed until you die.

Speculation: The word "speculation" used in futures and securities trading is not a derogatory term, but a neutral word, which refers to the trading behavior of seizing the opportunity and making use of the price difference in the market according to the judgment of the market. Speculators can "short" or "short". The purpose of speculation is very direct-that is, to make profits from the price difference. But speculation is risky.

3. Spread: refers to buying and selling two different futures contracts at the same time. Traders buy contracts that they think are "cheap" and sell those "high-priced" contracts at the same time, benefiting from the changing relationship between the prices of the two contracts. In arbitrage, traders are concerned about the mutual price relationship between contracts, not the absolute price level.
