Disliked{quote} It's a good question. Both instances can and often do slow price movement as you've noted. The main distinction for me lies in whether or not the market has tested the zone. The test will often manifest as pins into demand (or supply) - those blue lines on the second chart. If this occurs I would consider the demand zone to at least now be support (a kind of weakened demand if you will), that will potentially hold price up again but may give way altogether. If that pattern occurs as price generally moves up, I would consider it "compression"....Ignored
