Anyone notice the character of the Bond futures have changed dramatically the past few weeks. 1) those machines just bid, bid and bid -- one way street. 2) Used to B much more liquid at B/A -- very hard getting in and out. Once in can't get out. 3) they are pinning the market when the bids get going -- it doesn't come off. Flow at bid/a is choppy, jerky. Jumps all over the place. Wasn't like this in the past.
