I've always believed that the triangle pattern is one of the most practical tools in technical analysis. Recently, I organized some of these key patterns and want to share them with everyone.

First, let's talk about the descending triangle. This pattern features a gradually descending resistance line at the top and a horizontal support line at the bottom. When you see this pattern, it indicates increasing selling pressure. Once the price breaks below the support, a significant downward move often follows. Enter a trade after volume confirms the breakout—fake breakouts are really annoying, especially on charts with low volume. If there's already a clear downtrend, the accuracy of this pattern improves. Place your stop-loss just above the last resistance line.

Conversely, the ascending triangle is a bullish signal. It has a horizontal resistance line at the top and a gradually rising support line at the bottom. This shows that buying pressure is steadily accumulating. The entry point is clear: when the price breaks above the resistance line, confirmed by volume. This pattern is especially effective in an uptrend. Set your stop-loss just below the last support line, and look for new resistance levels to set profit targets.

Next is the symmetrical triangle. This pattern is interesting because it is neutral. The resistance line slopes downward, and the support line slopes upward, converging in the middle. The price may break out upward or downward, depending on which side has stronger buying or selling pressure. During formation, volume usually tapers off gradually, often signaling an imminent breakout. Wait for a confirmed breakout before entering—don't guess prematurely.

Finally, let's discuss the expanding triangle pattern, a shape that is often overlooked. Its characteristics are the opposite: support and resistance lines diverge, indicating increasing volatility. This usually occurs during periods of high market uncertainty or following major news. Trading within this pattern requires caution, as prices can swing wildly. After entering a trade, set wider stop-losses to give yourself enough room.

To summarize a few key points: First, volume is crucial. The larger the volume on a breakout, the more genuine the move, and the higher the probability of trend continuation. Second, these patterns perform best in clear trends—use ascending triangles in uptrends and descending triangles in downtrends for better accuracy. Third, risk management is essential. No matter the pattern, always set a stop-loss to protect your capital if the market moves against you.

Actually, these patterns are not complicated. The key is to observe and practice more in live trading, gradually developing sensitivity to these signals. If you're interested, you can find some suitable trading pairs on Gate and test these patterns yourself.
