Yet another new jargon word for you, but as far as I know, this is just my jargon word.
On my trade screen a positive Day Over Day change is green, no change=white, and negative change=red.
Since my screen configuration has Fannies, Freddies, Ginnies, treasuries, and multiple coupons for each, when some are up, some down, and some unchanged, it starts to look like an Italian Flag.
So that's a good sign for now... (in that we're not losing any more ground).
