CDS account is attached with respective brokers.

If one open CDS with ABC broker, then all shares traded under ABC broker will keep or withdraw through this ABC CDS. You can't transfer the ABC CDS to another broker house to use. So if one wants to trade using XYZ broker then one has open another CDS with XYZ broker.

The first 3 numbers of your CDS is indicating (xxx-xxx-xxxxxxx) which broker house of the CDS account is attached with. Bare in mind also. shares in CDS account can't be cross linked. So even you have TTT stocks in ABC CDS, you can't sell through XYZ broker, as XYZ broker has no access to ABC CDS, even though both account is under your name.

So if you want open an account with HLebroking, then you have to open a CDS with HLebroking, unless you have open one before with them, then don't need.
