Tradingmao is an online trading platform that provides trading services for stocks, futures and other financial products. Handling fees refer to the fees charged by TradingMall when users conduct transactions, which are used to maintain platform operations and provide services.

Specifically, the handling fee for trading cats is calculated based on a certain proportion of the transaction amount. Different transaction types and transaction amounts will have different handling rates. Generally speaking, the handling rate will be announced on the official website or trading software of Trading Cat. Users can check the specific handling rate based on their own trading conditions.

For example, assuming that the handling fee for a certain trading variety is 0.1%, and the user conducts a transaction of 1,000 yuan, then the handling fee is 1,000 yuan multiplied by 0.1%, which equals 1 yuan.

It should be noted that the handling fee is only a part of the fees charged by Trading Cat. There may be other fees, such as stamp duty, transfer fee, etc. The specific situation needs to be determined according to the transaction type and transaction rules.
