looking at my chart it had the signs of a reversal. on the 1000 volume i had a higher high and a higher low right before it took off.
This might be a moot point to you guys but I don't think the market reversed because of a double bottom, higher high/higher low, or some geometric shape. I think it reversed because key levels were held, namely NQ's morning lows and ES Previous LOD. Even if price poked slightly past the low instead of forming a nice double bottom, as long as buyers step up and the price level holds, price will reverse no matter what kind of shape it forms. Regarding the lunch time fade, backtest it and you will see patterns in which there will be times where you can get a scalp or a large move, and there will be times when it is not appropiate. The only thing the 30 min window does is put some added probabilities on your side. It is merely a tool that the trader can use to his/her advantage after sufficient knowledge of that tool.
Another thing about this market is that so far there is nothing bearish about the hourly or daily charts on both NQ/ES. And this is just my humble opinion but big money focuses more on these time frames than the shorter ones. So when you put this in context it makes a lot of sense that they took it right back up.
