Chart Patterns: The Classics
🔺 Traders swear they can see the future in shapes — triangles, flags, and something called a 'head and shoulders' that has nothing to do with shampoo. Here are the classics actually worth knowing.
💡 Key idea
Head & shoulders / double top = reversal hints. Triangles = coiling before a breakout. Flags = pause then continue.
🧠 Why it matters
Chart patterns are recurring shapes that hint at what price might do next. HEAD AND SHOULDERS (a peak, a higher peak, a lower peak) often signals a top/reversal. A DOUBLE TOP (two failed pushes at the same high) also hints at reversal; a DOUBLE BOTTOM is its bullish mirror. TRIANGLES show price coiling tighter until it breaks out one way. A FLAG is a brief pause within a strong trend before it continues. None are guarantees — they're probabilities the crowd often acts on.
🌍 In the real world
💡 Patterns can be self-fulfilling: when thousands of traders spot the same 'head and shoulders' and all sell, their selling is what actually pushes price down. The pattern 'works' partly because everyone believes it will.
📌 Takeaways
- Head & shoulders / double tops hint at reversals
- Triangles = price coiling toward a breakout
- Patterns are probabilities, partly self-fulfilling
✅ Test yourself
A 'head and shoulders' pattern often signals...

Part of WHY chart patterns work is...
- The SEC enforces them
- They're self-fulfilling — many traders act on the same shape
- They're 100% accurate
- Magic
Answer: B · They're self-fulfilling — many traders act on the same shape
