How did you come up with those specific times? If we are talking about eminis, or even stocks, a good time to trade is anytime there are most others traders trading as well. That will provide liquidity, and help push prices. Those times are 10 to11, and 2:30 to 4, EST. Just look at the volume, it says it all, those are the times. So, trade when others are trading, not when someone else is telling you to trade and disregards facts completelly.
