If you got that page on EPIC that usually prints out in ops for a trade, then it went through. Whether or not you got it is another story. They usually do two "pulls" every day. One at noon and the other at 5 pm and go through the add/drop/trade requests. All SAW requests are awarded on a first come first serve basis and also have to adhere to contractual and legality rules.

Technically, you can't request partial adds or drops during the SAW, although they have done it in the past. It depends on who the planner is and what mood they are in I guess.
