I've noticed that many beginners in trading get confused when they see a triangle on the chart. In reality, it's one of the most reliable patterns if you know how to read it. I'll tell you about the four main types that really help in trading.

Let's start with the descending triangle — it's a bearish pattern that indicates sellers are gradually gaining control. Do you see a horizontal support line at the bottom and a resistance line that slopes downward? That's a signal that selling pressure is increasing. When the price breaks through this support, a serious decline often begins. The main thing is not to fall for false breakouts. I always wait for confirmation with volume before opening a short position. I place the stop-loss above the last resistance line; this is a basic risk management rule.

The opposite is the ascending triangle. It's a bullish pattern that often appears during an uptrend. Here, there's a horizontal resistance line at the top and an increasing support line. Buyers are constantly trying to break the resistance, and with each attempt, pressure builds up. When a breakout occurs with good volume, it often leads to a strong rally. I open a buy position exactly on the breakout, but only if the volume confirms the move's seriousness.

Now about the symmetrical triangle — it's a neutral pattern that can go in any direction. Both lines converge toward the center: resistance decreases, support rises. This forms during consolidation, when the market is gathering strength before a big move. It's important to wait for a clear breakout rather than guessing where the price will go. I open a position only after the price clearly breaks one of the lines with volume. If upward — long, if downward — short. I place the stop-loss on the opposite side of the last line.

The most unstable option is the expanding triangle. Here, support and resistance lines diverge, and volatility increases. This usually happens in highly volatile markets or when important news is released. Trading such a triangle requires more caution — there's a lot of uncertainty. I open a position only after a breakout, and I place the stop-loss further away to avoid noise.

The main point for all types is volume. A breakout without volume is often a trap. The higher the volume after the breakout, the more likely the move will be serious. Also, these patterns work best when they form within a clear trend. An ascending triangle in an uptrend is more reliable than in a sideways market.

Overall, triangle trading is not magic; it's just logic. Sellers or buyers gradually accumulate positions, the chart compresses, and then an explosion happens. If you see such a pattern, don't rush. Wait for volume confirmation, set a stop-loss, and don't forget about risk management. That's what separates professionals from beginners. By the way, on Gate, you can track these patterns on charts of SUI, BONK, FLOKI, and other assets — a good way to practice and see how triangle trading works in real life.
