This is why people get confused by TA, they don't realize what it's showing. It's just market sentiment and human psychology.

Very simple examples: Traders buying at $3, stock goes to $6 and dumps, the buyers at $3 will probably not sell below $3 and a lot of people might average down, adding more support. Alternatively, $6 can act as resistance because of all the profit taking, lots of people doubled their money so the sellers are outpacing the buyers. If the price consolidates at resistance long enough, it usually means buyers are keeping pace with sellers and a breakout might be likely. Upward buying pressure breaks out from the selling pressure, and you get another price increase. Wowww, voodoo! That's support and resistance, consolidation, breakouts. Can even add in support turned resistance and resistance turned support. All very simple concepts that are the basis of TA and price action.

Some of the more wild indicators and stuff can get pretty silly (and outright stupid), but fundamentally TA is just a way of visualizing human behavior.
