1. Find one or more sample accounts, which can be real accounts or simulated accounts.

2. Use computer software to obtain real-time transaction data of these sample accounts, including ordering, closing positions, stop loss and other information.

3. Use the documentary software to reflect the transaction data of these sample accounts to the documentary accounts in real time, but in the opposite direction. For example, buy more sample accounts and sell short documentary accounts; If the sample account sells short, the documentary account buys more.
