What Are Chart Patterns?

Chart patterns are recurring shapes in price that mark where buyers and sellers are fighting. Here is how to read the eight that matter most, and why low-float penny stocks distort all of them.

A chart pattern is a shape that price keeps drawing whenever the same argument between buyers and sellers plays out. That is all a pattern is — a picture of who is winning, and where the fight is happening. The value is not that the shapes predict the future; it is that they tell you exactly which price level matters, so you know in advance what would prove you wrong.

Patterns split into two families. Continuation patterns (the three triangles) are pauses inside a move that usually resolve in the same direction. Reversal patterns (double tops and bottoms, head and shoulders) mark the end of one and the start of another. Every one of them is defined by a line that price has to break to confirm it, and until that break happens you have a drawing, not a signal.

Why Penny Stocks Distort All of Them

These patterns were described on liquid, heavily traded stocks. Sub-$5 stocks break the assumptions behind them in three specific ways, and it is worth knowing which before you trade one:

  • A low float exaggerates every break. The same buying that moves a large-cap 2% can move a 3M-float microcap 40%. Breakouts overshoot and reverse much harder than the textbook version.
  • The spread eats the edge. A clean pattern on a stock with a 10–20% bid-ask spread can be unprofitable even when you read it correctly.
  • Thin volume fakes the shape. A handful of trades at odd prices can draw a convincing triangle that represents no real supply and demand at all. Always check the pattern against actual dollar volume.

The rule that survives all three: volume confirms, price alone does not. A break on heavy volume is a decision. A break on nothing is noise that will be retraced by lunchtime.

What to Watch For

  • A pattern is only a pattern once the defining line breaks. Before that it is a drawing.
  • Volume confirms the break. A break on no volume is usually retraced the same session.
  • Continuation patterns (triangles) resume the prior move; reversal patterns end it.
  • Low float exaggerates every break, in both directions.
  • On a wide spread, a correctly read pattern can still lose money.
