I am a happy customer of Interactive Brokers. IBKR is my only broker because I cannot find a better alternative for investing in international stocks. The interest rates for margin is also superb.
Do members here think it is a bad risk management practice to use only one broker? How do you mitigate this single-point-of-failure risk?
In my opinion IB does a damn good job mitigating risk. Almost too well to the point that it's annoying to deal with their excess margin requirements for a lot of stuff. Generally speaking I'd agree but would make an exception for IB.
