且的逻辑关系

Logical AND Relationship

系统通常由多层限额组成一个限额体系，各层之间通常是且的关系，只有当一笔交易逐层穿透这个体系才能最终完成交易，从设计的角度要捋清逻辑、以免使得各层间相互矛盾。

Systems are typically composed of multiple limit layers, forming a limit system. The layers usually have an AND relationship, meaning that a transaction must penetrate each layer sequentially to be completed. From a design perspective, it is crucial to clarify the logic to avoid conflicts between layers.

限额方式

Limit Methods

通常为限制金额、个数（如开户个数）、笔数（如存入笔数）、份额（如奖品份额）。

Common methods include limiting the amount of money, the number of accounts (e.g., the number of accounts opened), the number of transactions (e.g., the number of deposits), and the share (e.g., the share of prizes).

限额维度

Limit Dimensions

从产品敞口到机构限额再到账户交易个数，可能从多个维度进行控制。

Control can be exercised across multiple dimensions, from product exposure to institutional limits, and down to the number of transactions per account.

限额周期

Limit Periods

通常以年/月/日为周期，到期后清零再重新累计，这取决于具体业务场景；以小时或者小单位为限额周期常为防止技术性攻击问题而设计。

Limits are typically reset annually, monthly, or daily, depending on the specific business scenario. Hourly or smaller unit limits are often designed to prevent technical attacks.
