Any plan includes some elements. One of the first decisions to make is to use the money to do foreign exchange. How much money is actually used depends on a lot of considerations: the first is a trader's motivation, and if it's just to try or play it, it's better to have less money. The other is the enterprise of the trader, who is willing to take much risk to make money. A related factor is the age of the trader, because it involves his family, health, seniority, and his family's attitude to his speculation. These are not insignificant factors. In summary, the most basic point is that traders should not risk the loss of a potential loss commensurate with their importance. Any transaction can be seen as a contract between the two parties. The so-called transaction cost can be seen as the cost of the transaction contract. According to Mr Coase and others, a type of transaction costs arise from the accidental factors that occur when a deal is signed. These incidental factors may not be written into the contract due to the fact that they could not be foreseen in advance, or although they could be foreseen, they could not be written into the contract due to too many factors. Another type of transaction costs is the signing of contracts and the cost of monitoring and enforcing contracts.
