I find this to be a gem:
"For the most part, W uses the term "thrust" generically -- thrust, upthrust, downthrust -- having the same meaning as that found in any dictionary. A synonym for it might be "poke". This particular kind of movement is made out of a sideways congestion to determine if there is any buying interest (if up) or selling interest (if down). An upward thrust can also be used to trap traders into buying if the ultimate intent is to drive price down. This not only helps to reduce demand, but may also aid the downward movement if the buyer is frighened into throwing his shares back onto the market.
A downward thrust is also called a shakeout, and its intent is the reverse, to determine if there is any selling interest and perhaps frighten holders into selling their shares in advance of a move upward. This reduces supply and enables those who are accumulating the shares to accumulate even more.
Upward and downward thrusts may also be used to catch the stops of those who are short or long, respectively.
W calls particular attention to "terminal" thrusts and "terminal" shakeouts, i.e., those which occur just before a breakout to the upside or downside as part of the preparation for the ultimate move. However, it's next to impossible to determine whether or not these are "terminal" except in hindsight, so the value of knowing what these are and what they mean is to be able to interpret the motives behind the movements in real time if the "breakout" quickly fails."
