The process of transferring stocks from Snowball X to Longbridge mainly involves two steps: notifying Longbridge to receive the stocks and notifying Interactive Brokers (IB) to transfer the stocks out. Below are the detailed description for these two steps.
Step 1. Go to the Longbridge App > Portfolio > Transfer to submit a transfer-in application. If you have already deposited funds, select Portfolio > More > Share Transfer-In.


Step 2. Fill in stock transfer details. Select Snowball X as the transfer-out broker, enter the account holder's name and account number, click Next, and fill in the stock information.
Please note: Longbridge now supports entering the cost price per share (optional).
Step 3. Confirm stock transfer details and submit the transfer.
Step 1. Log in to the official website of IB to submit an application for transferring stocks out.
(1) Obtain IB login account information from Snowball X
Log in to Snowball X, select My > Account > Snowball X Backend System Account/Initial Password to query the Snowball X backend system account and initial password.

(2) Log in to the IB official website: https://www.interactivebrokers.com.hk/en/home.php
(3) Log in to your IB account
Use the obtained Snowball X backend system account and initial password to log in. If you have set a new password, use the new password to log in.
If the password is incorrect, you can click Forgot Password or call Snowball X/IB customer service to retrieve it. IB customer service phone: +86 (021) 60868586.
(4) Obtain IB account information
After logging in to the IB official website, the account number in the portfolio section is your IB account number. You can also obtain the U account number (this account information is required when submitting the transfer-in application to Longbridge) from the Snowball X app account.

Step 2. Submit instructions for transferring stocks out.
