Quote from Spydertrader:
Many times, the market has provided examples where a Tape widens out and becomes a Traverse, or in this case, where a Traverse widens out to form a Channel. The exact point in time for such an event, occurs when that which defines a certain thing exists on one's chart. However, the market does provide clues in advance of the event horizen. Since the market builds Tapes, Traverses and Channels in very specific ways, one simply needs to learn to see the initial delivery of constuction materials arrive on sight, and after noting which materials arrived in the delivery, one can know what the market plans to build.
