Advanced chart patterns
Beyond the basics lie harmonic sketches, broadening formations and gaps — lower-frequency, higher-nuance structures. Learn what they look like, when they justify attention, and why position size should shrink as complexity rises.

Key takeaways
- Advanced patterns are filters on core structure — never standalone systems.
- Gaps classify by location and volume; most opening gaps are noise, some are repricing.
- Complexity costs money — size down as pattern rarity rises.
Lesson 1
ABCD and measured symmetry
- AB impulse, BC retrace (~50–62%), CD extension (~127–162%) — symmetry projects the D zone.
- Works best in orderly large-cap trends, worst in news-driven mid-caps.
- D is a zone to watch for reversal candles, not a blind limit order.
Lesson 2
Broadening and expanding formations
- Higher highs + lower lows = disagreement expanding — volatility regime, reduce size.
- Breaks from broadening tops fail often; wait for close + retest.
- Common near major events (elections, budgets) on Nifty itself.
Lesson 3
Gaps: breakaway, runaway, exhaustion
- Breakaway gap on volume through a level = genuine repricing (results, policy).
- Runaway gaps mid-trend often hold; exhaustion gaps after vertical runs fill fast.
- NSE opening gaps from global cues fill intraday more often than traders expect — don't chase the first 15 minutes.
Lesson 4
Complexity budget
- Rarer patterns need larger samples to trust — halve size until you've logged 20+ occurrences.
- If a pattern needs five Fibonacci ratios to 'work', it doesn't work for execution.
- Prefer the simple version: structure + volume + one indicator over harmonic perfection.
Mistakes that cost money
- Drawing ABCDs on every wiggle and trading imaginary D zones.
- Shorting broadening formations mid-expansion instead of waiting for resolution.
- Chasing gap-ups 4%+ into resistance on global-cue mornings.
Chapter FAQ
Do harmonic patterns work on Indian stocks?
Approximately — liquid large-caps respect symmetry better than thin small-caps. Treat D zones as alert areas with candle confirmation, not precise reversal points.
Should I trade every gap?
No. Trade breakaway gaps through levels on volume; fade exhaustion gaps into resistance; ignore small opening gaps under 0.5% on Nifty.
Broadening top — bullish or bearish?
Neutral-to-bearish at tops after long rallies, but resolution decides. These patterns expand before they resolve — patience and smaller size are the edge.
