No, but hindsight only proves it. The rule is TL's are drawn from the peak to the first swing high (in the last of a DOWN). Beyond that, others might be legitimate, but only hindsight would tell us that.
Let me be clear that TL's only usage is not the parameters as originally described in this thread, but within the context of why I started this thread there is only one usage for them.
Let me repeat. A high yield, low risk, high probability trade is made under the following criteria:
1. TL drawn from the peak/ dip to the swing high/ low.
2. Watch for break of the TL.
3. Once it is broken, it will continue in the direction of the new trend.
4. Afterward, it will correct anywhere from the point of break to the TL itself. That area is the point of entry.
5. The move will reverse from that point of entry to going deeper than the original break of the TL.

See how far has the price moved away from the trend line made of high / swing high. If it moved 100 points for example, it is likely to move 100 points in the opposite direction ... give or take a few. After that it may consolidate and move further, or just reverse, or consolidate and reverse ... that you can not predict. This is just about what happens at point 5.
This is just a simplification of Demark, for more nuance read his section on price projections in his book on TA.
