It probably stops at 1:00. I had the same problem. I wanted to buy K's and they took off while the Internet was down yesterday morning. I don't believe the P's will go back into the 20s again with all that's going on right now. I took profit on the P's and put it in the U's, thinking the P's would then come down and U's go up. Didn't happen. I do have extra shares of U's now.
