QuoteDislikedit's dog eat dog out there. I think he is referring to the "pro's" having retail accounts as well as institutional to hit it with as much as they can. You would be able to get more liquidity this way instead of just running with one straight institutional account which may not provide you with enough liquidity, especially during illiquid times which is the favored time to strike.
I guess what makes them pro's is that they are ex-interbank traders with contacts, as well as enough cash to move the market.
Cautiously optimistic. . .
