The process of transferring stocks from Interactive Brokers (IB) to Longbridge mainly involves two steps: submitting a transfer-in request to Longbridge and submitting a transfer-out request to IB (the processes of Hong Kong and US stock transfer-out are different). Below are the detailed descriptions 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. Select IB 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).
Hong Kong stock transfer-out
Note: This operation process only applies to personal accounts under IB. If you are a user of Snowball X, you can also follow this process; if you are a user of Tiger Brokers, you are advised to contact the customer service of Tiger Brokers to consult and confirm the transfer process.
Step 1. Log in to the IB website: https://www.interactivebrokers.com.hk/en/home.php
Step 2. Submit instructions for transferring stocks out.
(1) Path: Transfer & Pay > Transfer Positions > Transfer Out > Basic FOP Transfer

Step 3. Wait for IB to contact you to provide a letter of authorization. Fill in and submit the letter. After submitting the application in Message Center, wait for IB to contact you—some users will be notified that they need to provide a letter of authorization. If IB contacts you, fill in and submit the letter. An example of the letter of authorization is as follows:
