"Even the slightest movement, over the weekend, into next week, of compromise and it looks like they're going to get something, then this market is setting up, you can actually feel it that it's getting ready to take off," said Kenny Polcari, a CNBC contributor and director of NYSE floor operations for O'Neil Securities.
