Not every day, BUT
More often than not oil prices dip at 11:30 eastern when the Euro Markets close and it takes a few minutes before the North American markets pick up the slack in volume to support price. I have noticed that oil based stock prices often follow this dip as well. Selling close to the open and rebuying just after 11:30 has worked for me 6 out of 9 days. I never sell all but it is fun to play 25% of my BTE. I have averaged down 17 cents over 9 days this way (on the 25% only)
