Dude, you really sound like a newly rich Chinese kid who got sent to a college in the US and was equipped with a bit of "play money". Maybe I am incorrect but this is my hunch.
What seems to be correct, though, is that you are completely green behind the ears (=inexperienced) but you want "the best" "the most", "the cheapest", "the safest", as MANY OTHER USERS pointed out there is no broker that offers all that together.
BECAUSE you seem a newbie I recommend you actually forget about your 500k in your pockets, you take 50k of it and trade it with a broker that affords you to put on trades without raping you through commissions and execution related various other charges. I still do not get what issue you have with IB nor do many other users who repeatedly asked you about your aversion re IB. Why would you want to put up your full 500k if you are seemingly inexperienced. Just because you day traded a little in China and made a bit (or a bunch?) does not mean you are an experienced trader nor does it mean you will be consistently profitable. I come across people like you all the time, people of the "I want to make a killing in the shortest period of time, so show me the broker who can allow me to meet my goals". Generally (almost always) this pipe dream ends up in tears, or at least massive frustration.
I recommend again: Take 10% of your notional, and put it into an account that is safe enough but if worst comes to worst you are not dead even if the world ends and brokers go out of business. After you proved yourself you can afford to ask for prime brokers and brokers that target HNW individuals. My 2 cents, take it or leave it but your current hunt for Merrill Lynch or others that TOTALLY DO NOT FIT YOUR PROFILE makes ZERO SENSE TO ME.

Quote from tonyzhou:
I do not know what other company can offer, so frankly, I am not clearly know what I can get.
The following is my current "demand" for a second account (I know many of you have several account for different purpose)
Safety. One concern is of course broker failure. Though SIPF insurance, I read somewhere that a very few people still lost part of the money when their asset is large. But this is not the main one. I think identity stolen is not covered by SIPF. If someone have your password and damage one account, at least another account is safe.
Short ability. IB has great short. But many times, I still cannot get the borrow. So if a second broker can offer great borrow, I will have a second place as backup.
Commission: It is nice if the commission is comparable or lower than IB if they offer better commission for account with assets 500K than some account with only $5K.
Again, I do not know what other company can offer. If they can offer more service for a 500K account than a 5K account, it would be great.
Strategy running:
1. contrary strategy. If stock hot, short it. Holding a few hours to a few days
2. Two long strategy based on stock ranking. One covers small cap based on fundamental, average turnover, 2 month. One covers mid cap based on up estimates, average turnover, 2 weeks
Allocation: each strategy get 1/3 fund. No leverage used. Long holding 5 stocks, Short holding 10 stocks
