Quote from dbphoenix:
About this midpoint thing. This morning provided a good example of what happens around these levels.
After midnight, traders futzed around between 29.5 and 32 for a while. After they got bored with that, they scouted around for something new, and they settled into a range of sorts between 33 at 0500 and 37 at 0720. Midpoint? 35.
They then dropped to 31 at 0820, rallying to 40 at 0910. Midpoint? 35.5. See the pattern here? And it's established well before the open. So unless one just loves being chopped up in congestion, he needs to avoid 35+. In fact, he needs to avoid this entire range since there's no repeatedly-tested support or resistance. It is a go-mow-the-lawn day. If one wants to sit and watch traders eat donuts and surf porn, that's up to him. But he's better off setting his alarms and doing something more productive.
Incidentally, these congestions generally serve as a sort of reset, like a road trip where you pull off at a rest stop at a major crossroads and have a discussion about where you want to go next. The Line Of Least Resistance may have gotten you there, but it may not necessarily propel you forward. It may go left. Or right. Or it may back up a bit to see that historical marker it missed on the way.
