1. Contract varieties
2. Open position direction: buy open position (bullish) or sell open position (bearish)
3. Point: similar to the price of stock investment.
4. Number of lots: similar to stocks.
Win or lose is always: sell-buy.
If you are bullish, you are actually the same as stocks. Buy low and sell high. Being bearish is similar to selling at a high price and then buying a hedge at a low price.
Futures and spot are completely different. Spot is actually a tradable commodity. Futures are mainly not commodities, but standardized tradable contracts with some bulk products such as cotton, soybeans and oil and financial assets such as stocks and bonds as the targets. Therefore, the subject matter can be commodities (such as gold, crude oil and agricultural products) or financial instruments.
