Compare the similarities and differences among futures trading, credit trading and option trading.
I haven't heard of credit transactions. Futures trading is a futures contract, and option trading is the right to buy and sell a certain subject matter at a specific price. There should be no way to use options to predict the decline of securities prices, and technical and fundamental analysis is needed to predict prices. But options can avoid the risk of rising futures prices. Take stock index futures as an example. You want to buy stock index futures at some time in the future, but you are worried that the price will rise. So during the period when you want to trade in the future, you buy stock index options with a small price premium and the price in your mind as the exercise price. If the stock index really rises in the future, then you can exercise it, so that you can buy a cheap stock index at the price in your mind. The higher the market price, the greater the income. If the stock index price does not rise but falls, then you can give up the exercise right and buy the stock index directly at the market price, then you will only lose your power at most.
