In the development process of the commodity economy, as the scale of the securities circulation market expands and the turnover of transactions increases, the securities trading methods develop from simple to complex, from low-level to high-level, and from single to compound. In terms of the time of securities circulation and buying and selling, that is, based on the length of the period from contract signing to performance of the securities transaction between the two parties, securities trading methods can be divided into securities spot trading, securities futures trading, securities options trading, securities credit trading and securities repurchase. Five forms of transactions. Among them, futures trading and options trading are considered to be the products of Western financial market innovation in the 1970s, and have been rapidly promoted and developed in emerging securities markets. Legal objectivity:

1. Spot transaction The so-called spot transaction means that the buyer and seller of securities go through the settlement procedures after the transaction is completed. The buyer pays the funds and gets the securities, and the seller delivers the securities and gets the funds. Therefore, the characteristic of spot trading is "pay with one hand and deliver with the other hand", that is, the transaction is carried out by buying spot with cash. 2. Forward transactions and futures transactions Forward transactions are when both parties agree to conduct transactions at a certain time in the future (or within a time period) at the currently determined price. Futures trading is a standardized forward transaction conducted on an exchange, that is, a futures contract transaction conducted by both parties in a centralized market through open bidding. A futures contract is a standardized agreement signed by two parties to deliver a certain quantity of a certain commodity on a certain date in the future at a price agreed upon at the time of transaction. Futures trading is similar to forward trading in that both contracts are concluded now and delivered in the future. However, forward transactions are non-standardized and are conducted in the over-the-counter market; futures transactions are standardized and have contracts in a prescribed format and are generally conducted in the on-site market. In addition, spot trading and forward trading aim to obtain the subject matter through trading; while futures trading does not carry out physical delivery in most cases, but reverse trading and liquidation before the contract expires. 3. Repurchase transactions Repurchase transactions have more attributes of short-term financing. From the perspective of operation, it combines the characteristics of spot trading and forward trading, and is usually used in bond trading. Bond repurchase transactions refer to the behavior in which bond buyers and sellers agree to conduct reverse transactions at a certain price at a certain time during the transaction. In bond online shopping transactions, when bond holders have short-term funding needs, they can pledge or sell the bonds they hold to raise funds; conversely, the fund supplier will raise funds within the corresponding period. Transfer the right to use funds and receive a certain interest return. 4. Credit trading Credit trading is a transaction in which investors obtain the credit of a broker by paying a margin, also known as "margin and securities lending transactions". The main feature of this transaction is that the broker provides credit to the investor, that is, part of the investor's funds or securities for buying and selling securities are borrowed from the broker.
