For those who are confused by the labels (which are cryptic), they are, in order:
PSY - Preliminary supply, where volume starts to flow
BC - Buying climax, where the spreads are high and volatility goes up on max volume
AR - Automatic reaction, After a large move, the market does an automatic reaction, where traders reassess the move, taking profits, and setting support.
SC - Secondary test, where the market goes close to the area of the buying climax and is met with resistance.
Creek - The area between supports and resistances, where price moves in soft price action and lower volume.
Spring - After breaking support, there is a panic session, which, if bullish, springs back into the trading range.
Test - Before moving into higher highs, the resistance from the creek might be tested before volume starts to rise.
Crossing the test with increasing volume is "Jump the creek", which ends in retesting of the resistances and finally breaking into a higher move.
