in the UK... a lot of offices in old pre-war buildings... so this doesn't look unusual

also tradestation-global is introducing broker to ibkr...so a PO box and a few staff is probably expected...

When you bank in money, you bank into IBKR not the Whitelabel (e.g. TradeStation).
So you have nothing to worry about.

When you buy insurance, you bank in money to the insurance company not your agent.
Similarly, when you buy stocks in Malaysia, you bank into your IB bank account not your remisier's.

insurance I bank to agent wor...

Hmm. That's weird. Should be direct to the insurance entity but I'm no insurance expert.

I am no expert as well and i do find that weird, but i guess if you get an official receipt should be no problem

I think if it's agent for the insurance company you pay the company

if agent set up agency...then can pay them or pay direct

so far so good... they activate renewal before I even pay up...lol

I have an existing IKBR PRO account, when I try to link to Tradestation, it says not valid

cannot link. is treated like separate company.

linking for sub accounts valid only under same company
