Why Patterns Work (When They Work)
Chart patterns aren't magic. They work because they reflect repeating human behavior:
- A double top = "twice the market tried to break higher and failed"
- A flag = "buyers are taking a breath after a sharp run-up"
- A head-and-shoulders = "the third rally couldn't make a new high"
The pattern itself is just a visual shorthand for what other traders are doing.
Continuation Patterns (the trend pauses, then resumes)
Bull Flag
A sharp rally (the "pole") followed by a tight, downward-sloping consolidation (the "flag"). Often breaks out in the same direction as the pole.
Target: add the pole's height to the breakout point.
Pennant
Like a flag but the consolidation forms a small symmetrical triangle. Same logic, same target.
Ascending Triangle
A flat resistance line with a rising support line — buyers getting more aggressive while sellers stay fixed at the same level. Often resolves up.
Descending Triangle
The opposite — flat support, falling resistance. Sellers getting bolder. Often resolves down.
Reversal Patterns (the trend may be ending)
Double Top
Price hits the same high twice and fails to break through. A break below the dip between the two peaks confirms the reversal.
Target: subtract the pattern's height from the neckline.
Double Bottom
Mirror image — two equal lows, then a break above the middle high. Often a strong bullish reversal.
Head and Shoulders
Three peaks, with the middle (the "head") highest. A break below the "neckline" connecting the lows is one of the most-watched bearish reversal patterns.
Inverse Head and Shoulders
Same shape upside-down — a powerful bullish reversal pattern at the bottom of a downtrend.
Symmetrical Triangle — The Coin Flip
Lower highs and higher lows converging into a point. Direction is uncertain until the breakout. Don't anticipate — wait for the move.
Measured Moves
Most patterns come with a built-in price target:
- Flag/pennant: flagpole height projected from breakout
- Triangle: triangle's widest height projected from breakout
- H&S / double top: pattern height subtracted from the neckline
These aren't guarantees — just expected ranges based on the pattern's history.
How to Use Patterns Without Fooling Yourself
- Wait for confirmation. A pattern that hasn't broken out yet is just a guess.
- Demand volume. Real breakouts come with above-average volume.
- Set a stop. If the pattern fails (price quickly moves back inside), get out fast.
- Use the higher timeframe. Patterns on the daily/weekly are more reliable than 5-minute patterns.
- Pattern + trend + level. A bull flag in an uptrend at known support is much higher quality than a random shape on a random chart.
The Honest Truth
Chart patterns work more often than chance — but they fail constantly. The edge comes not from being right every time, but from:
- Cutting losses fast when patterns fail
- Letting winners run when they work
- Sizing positions properly so a few losses don't matter
Pattern recognition is pattern probability. Treat every signal as "the odds favor X" — never as "X is guaranteed." That mindset is what separates the survivors from the broke.
