A chart pattern isn't magic โ it's a visual record of a specific kind of struggle between buyers and sellers that tends to repeat, because the same market psychology shows up again and again. Here are the patterns that genuinely earn their reputation, without trying to memorize an exhaustive catalog of every named shape that's ever been drawn on a chart.
Double Top and Double Bottom
Price reaches a high, pulls back, rallies again to almost the exact same high, and fails there a second time. That's a double top โ real evidence that a specific price level has now rejected buyers twice, not once. A double bottom is the mirror image at a low.
What makes this meaningful isn't the shape itself โ it's that the second failure at the same level is stronger evidence than the first. One rejection could be coincidence. Two, at nearly the same price, means real sellers (or buyers, for a double bottom) are genuinely defending that level.
Head and Shoulders
Three peaks, with the middle one higher than the two on either side โ like a head between two shoulders. This pattern reflects a real shift in control: the first shoulder shows buyers still strong, the head shows one final push higher, and the second shoulder shows buyers failing to reach that high again โ a real sign that buying pressure is fading before sellers take over.
The "neckline" โ a support level connecting the two lows between the peaks โ matters more than the peaks themselves. The pattern isn't considered complete until price actually breaks that neckline, the same "wait for real confirmation, not just the shape" discipline that applies to any breakout.
Triangles
Price makes a series of highs and lows that squeeze closer together, like the market is compressing before a decision. A triangle reflects genuine indecision โ neither side has enough force to win yet, so the range keeps narrowing until something finally breaks.
The direction of the eventual breakout matters far more than the triangle itself. A triangle only tells you a decision is coming, not which way it'll go โ that's exactly why entering during the squeeze, guessing the direction, is far riskier than waiting for the actual break.
Why patterns fail โ same logic as any fakeout
Every one of these patterns can fail the same way any breakout can: price can push through a neckline or triangle boundary, look convincing, and then reverse. This isn't a flaw specific to chart patterns โ it's the same real phenomenon covered in what a fakeout actually is. A pattern completing on paper doesn't guarantee the move that's supposed to follow it.
The common beginner mistake
New traders often start seeing patterns everywhere once they learn the names โ forcing a "head and shoulders" onto price action that's really just noise. A real pattern has clean, recognizable structure. If you're squinting and mentally rounding off the shape to make it fit, it probably isn't one.
SonaPips doesn't trade off pattern names โ it watches whether a real structural move actually holds on the higher timeframe, the same underlying question every pattern here is really trying to answer.
