Alright folks:
So here is a chart that shows a simple system for trading the ES using Clayburg's DDF.
Trading the open is actually not a complex as one might think. You simply watch the first bar (or candle), put in your line and then quickly get ready to trade long or short (long above the high of the first candle or bar, short below). I would be looking for two ES points, and letting it go to B/E shy of that. Also I show a reversal trade. I have found that if you close that first trade at B/E, it pays to reverse (looking again to take 2 points).
Notice the vertical line through the 60 min candle. Clayburg suggests that you look at how the action is distributed within this opening 60 min window. Is the majority of the price action above the DDF line, or below? If above, then look to trade long, expecting price to move above (perhaps trending) the rest of the day. If below, just the reverse.
I have seen good professionals use this as the framework for both equities and futures index trading. I used it for a while myself (along with pivots).
Check it out. Make up your own mind.

By the way, in the interest of full disclosure I do not trade this system today. If you read Dr. Clayburg's books or comments, you will note that he has tested his DDF indicator, suggesting that it is about 75% accurate (indicator of future price movement). In contrast I use another system that provides setups with 80, 87, and 95% accuracy. Naturally I am going to go with that instead. I figure however that an intelligent person looking at this could add a filter or two and bump up the performance a bit.
