Mamm usually has four ways to place an order. The fund manager has five trading accounts, all of which are 1000 USD. Trading accounts are 1 account, No.2 account, No.3 account, No.4 account and No.5 account. If our preset trading volume is 1 lot, then put 0.2 lots in account 1 and 0.2 lots in accounts 2, 3, 4 and 5, which adds up to 1 lot.

Take five accounts as an example. Account 1 has 1000 USD, account 2 has 500 USD, account 3 has 300 USD, account 4 has 200 USD, and account 5 has 100 USD. If our preset transaction is the first hand and the accounts 1, 2, 3, 4 and 5 are all the next hands, then there are always five hands.
