If you want to see support, take a look at Tuesday thru Friday of this week. The gap from Monday to Tuesday held very well. There was selling from the highs down to it but not through it. Each time the market came down you could see the congestion building and the eventual bounce off that area. If you were short there, you probably got steamrolled.
The resistance this week at the top of the range (in my opinion) was not an area to be viewed as the absolute top. Since we have been in an uptrend, you can't rely on this area to stop the advance even though it does tie into some significant longer term technical points.
Traders overall have been rewarded recently buying the dips rather than selling the rallies. Although selective shorting does work, it isn't like it was earlier this year. That in itself makes it feel different than the past rallies.
