Then likely best bet from my exp. is aggregation on front end. You get the tightest prices thats for sure by snapping them all on the click.. to 5, 6, 7 or heck 10 venues. And you'd certainly know your rate at the click was better than RFQ'ing the same amount.Quote from RockshoreFX:
We like the fact of knowing what the depth is, but its a better situation when you can aggregate the top and one click them all.

R.O.F.L. I can't stop laughing here...
