OK, now for how to enter. The way I see it there are at least 2 ways.
1. After the breakout, from the 46 area,the price climbed about 5-5.5 points, (to 1451+/- ) and then found some R.
One could have simply put in a limit order at around the 47 area,( the top of previous congestion) and hope that what you're seeing is in fact a pullback, from a successful breakout. And a stop at 44.5, figuring that a pull back that far is actually not a pullback, but rather a return to congestion, for further churning.
2. The other way, is to wait till you're sure that you are in fact looking at a pullback, and enter at the highest high, of the last down bar, with a stop loss set at the bottom of the same bar.
The stop loss's would be about the same distance from entry, And in both cases, the stop loss being triggered would tell the same story, a return to congestion.
