%%if a broker's systems go down they are unable to answer a flood of incoming calls. what difference does it make.
if you have SIPIC issues on your mind you have too much in the market.
Well that maybe a common problem ,zdreg but not the brokers fault -- too large trading- too /much in market. NOT likely your first sentence applies to AMTD;+ its up 100% past 52 weeks, not a stock tip or predicton.
Actually the IB [Interactive Brokers advice, get 2 accounts] was not maybe not limited to SIPC; its diversification of location+ most likely IB does not want you putting all eggs in one basket.
