# Cash Plus Trading Rules

[Table of Contents](https://longbridge.com/hk/en/support/toc.md)

This article explains the automatic investment/redemption mechanism, trading time, and cycle of Cash Plus.

**1\. Automatic investment:**

After you enable Cash Plus, idle funds in your Longbridge Securities account will be automatically invested into the corresponding money market fund. 

**2\. Automatic redemption:**

-   When deductions occur (e.g., for purchasing stocks or other products and withdrawals), holdings in the money market fund will be automatically redeemed as needed.
-   All holdings will be redeemed when the automatic investment agreement is terminated.

**3\. Trading time:**

Automatic investment/redemption occurs at a fixed time every day, with no need to specify trading time.

**4\. Cycle:**

Funds are automatically invested into the money market fund and begin accruing returns within one trading day after arriving in the account.

Note: Processing time is calculated based on Hong Kong trading days and will be postponed during holidays.

**5\. Calculation of 7-day earnings and 7-day annualized yield:**

This metric is annualized based on the net return calculated from the most recent 7 calendar days and does not represent the actual one-year return.

**Key points**:

-   Automatic investment: Idle funds automatically invested after signing agreement.
-   Automatic redemption: Automatic fund redemption for deductions; full redemption upon agreement cancellation.
-   Processing Time: Funds invested within 1 working day (postponed on holidays).
-   Earning calculation: 7-day earnings and annualized yield displayed based on calendar days.
