Let's understand the main triangle patterns that truly help in trading. I've noticed that many traders ignore these signals, even though they provide quite clear indications of price movement.

Starting with the descending triangle — this is a bearish pattern formed by a horizontal support line at the bottom and a descending resistance line at the top. See, when the price repeatedly fails to rise above the previous level but hits the same support — that's a clear signal. Sellers are increasing pressure. Enter a short position after a support breakout, but always watch the volume — without it, it could be a trap. Place your stop-loss above the last resistance line.

The opposite situation is the ascending triangle. This is a bullish pattern with a horizontal resistance line at the top and an upward support line at the bottom. I usually see such patterns in the middle of an uptrend, when buyers are gradually taking control. Each time, the price jumps higher but hits the same level. When it finally breaks this level on increasing volume — that's a good buy signal. You can set your stop below the last support.

The symmetrical triangle is an interesting pattern. Here, the resistance line is descending, and the support line is ascending, converging together. This is a neutral pattern that can go either way. It usually forms during consolidation when prices fluctuate with lower highs and higher lows. The main rule — don’t enter until a clear breakout occurs. When the price breaks one side with good volume, then I open a position in the direction of the breakout.

Now about the expanding triangle pattern — this is a completely different story. Here, the support and resistance lines diverge, moving further apart. The expanding triangle signals increasing volatility and market instability. This usually happens when there’s a big difference in strength between buyers and sellers. I open positions after a breakout but with more caution, because the expanding triangle pattern can be very unpredictable. Place your stop-loss beyond the farthest point of the pattern.

A few practical tips that really work. First — always watch the volume. An increase in volume after a breakout strengthens the signal. The higher the volume, the higher the probability of a strong move. Second — trend context. These patterns work more accurately within a clear trend. An ascending triangle better captures uptrends, a descending triangle — downtrends. Third — risk management. Stop-loss is not optional; it’s essential to protect your capital from unexpected moves.

Beware of false breakouts, especially on charts with low volume. A decrease in volume during pattern formation can be a precursor to a breakout. Expanding triangles more often appear in volatile markets or when important news is released. Understanding these patterns truly improves trading accuracy. The main thing — don’t rush, wait for clear signals, and always follow risk management.
