Alternation Inside Corrective Structures
A practical walkthrough of sharp-versus-sideways alternation using Hang Seng historical bars from recent clinic worksheets.
Alternation is easy to recite and harder to draw. When wave two is a sharp zigzag, wave four often prefers a sideways triangle or flat — but charts rarely hand you textbook geometry.
During Impulse & Correction Lab sessions, we freeze the chart after wave two is complete and ask participants to forecast the character of wave four before revealing the later bars. That habit trains expectation without locking the mind.
If both two and four look sharp, we do not invent a missing sideways period. Instead we re-examine degree: one of those corrections may belong one degree lower.
Keep a simple ledger: depth of retracement, time consumed, and overlap with prior impulse territory. Those three columns catch most alternation mistakes before they harden into a published count.
