I noticed that many beginner traders get confused with chart patterns, so I decided to understand the four main triangular patterns that really help to understand where the price might move.

Starting with the descending triangle — this is a bearish pattern formed by horizontal support at the bottom and a descending resistance line at the top. You can see how sellers gradually take control, the price can't rise above the resistance each time, and eventually breaks support downward. When entering a sell position, it's important to wait for increased volume — this confirms that the breakout is genuine, not a false signal. I place the stop-loss above the last resistance line to protect against a sudden reversal. By the way, this triangle pattern works more accurately when volume decreases as it approaches support.

The opposite is the ascending triangle, a bullish pattern with a horizontal resistance line at the top and rising support at the bottom. This signals increasing demand. When the price breaks resistance with good volume, I open a buy position. I close it when the price reaches a new resistance zone or shows signs of overbought conditions. I place the stop-loss below the last support line. This pattern works especially well if there's already an uptrend.

The symmetrical triangle is a neutral pattern that can go in any direction. Resistance decreases, support rises, and the price compresses. It forms during consolidation, with lower highs and higher lows. The main thing here is to wait for a clear breakout and enter in the direction of this breakout with strong volume. If the breakout is upward — I buy; if downward — I sell. I place the stop-loss on the opposite side of the last line. Often, volume decreases before the breakout, signaling an imminent move.

The fourth triangle is the expanding one, the most unstable of the four. Here, support and resistance lines diverge, and volatility increases. This can indicate a potential reversal, but you need to be more cautious than with other patterns. I open a position after the breakout and close it when the target is reached or momentum is lost. I place the stop-loss beyond the farthest point of the pattern. Such patterns often appear in volatile markets or before major news.

General principles for all: volume is confirmation. If the breakout occurs with increasing volume, the likelihood of a significant move is higher. Second — the trend context. The ascending and descending triangles work better if they form within the respective trends. And third — always use a stop-loss; it protects against unexpected reversals.

Practically, when I analyze a chart and see a forming triangle pattern, I first wait for confirmation, then look at the volume, and only then make a decision. False breakouts happen, especially on low volume, so there's no need to rush. Understanding these four models really helps improve accuracy in technical analysis and makes trading more systematic.
