Alternation on Hong Kong Index Charts

Using alternation between second and fourth waves when reading Hang Seng related structures in clinic packs.

Alternation is easy to recite and hard to trust when a familiar index prints an awkward fourth wave. Our Corrective Pattern Lab uses Hang Seng and related futures prints precisely because local readers already feel the rhythm of those swings.

If the second wave was a sharp zigzag, expect the fourth to lean sideways — flat, triangle, or combination. When both second and fourth look sharp, one of the labels is usually wrong, or the larger degree is misidentified.

We discourage forcing a triangle simply because price has paused. Triangles need clear A–E legs and converging boundaries. A pause with no five-leg skeleton is often still a flat or an unfinished zigzag.

Clinic packs include intentionally incomplete corrections. Participants must write “insufficient structure” rather than invent a label. That honesty prevents decorative annotation.

Practice alternation on markets you already watch. Familiarity with the tape frees attention for labeling rules instead of guessing what price “should” do next.
