I've noticed that many traders get confused with triangle patterns on charts. In reality, they are some of the most reliable signals for entering a position. I'll explain how I see and use them.

I'll start with the descending triangle – a bearish pattern that often precedes a significant drop. It forms simply: horizontal support at the bottom and a resistance line above that gradually slopes downward. You can see how sellers become stronger with each attempt for the price to bounce up. When the descending triangle reaches its apex, pressure increases. It makes sense to enter a short after a breakout below support, but it's important to wait for volume to increase – this confirms that the breakout is real and not a false signal. I place a stop-loss above the last resistance line. I close the position either at a new support level or if I see signs of a reversal.

The opposite is the ascending triangle. This is a bullish pattern that usually appears during an uptrend. A horizontal resistance line at the top and a support line below that is rising. This shows that buyers are becoming more aggressive. When the price breaks resistance with good volume, it's a signal to go long. I set the stop below the last support. I close when I reach targets or see overbought signs.

Now, the symmetrical triangle – the most interesting pattern because it’s unpredictable. Resistance decreases, support rises, and you don’t know which way the breakout will go. It’s consolidation, where the price moves with lower highs and higher lows. The key here is not to enter before a clear breakout. When volume drops during formation, it often indicates a sharp move is coming soon. If the breakout is upward – I go long; downward – I go short. I place a stop-loss beyond the opposite side of the last line.

And finally, the expanding triangle. This is a complex pattern because support and resistance lines diverge outward, showing increasing volatility. It usually appears when there’s high market uncertainty or important news releases. Entering a position should be cautious because movements are unpredictable. I set the stop-loss at the furthest point of the pattern.

General rules I always follow: first, volume is king. An increase in volume after a breakout strengthens the signal and increases the likelihood of a significant move. Second, I look at the previous trend. Ascending and descending triangles work better if they appear within an existing trend. And third, I always use a stop-loss – it’s protection against unexpected market moves that could wipe out the entire capital.

Practice shows that understanding these four patterns – descending triangle, ascending, symmetrical, and expanding – significantly improves accuracy in technical analysis. The main thing is not to rush into entries, wait for volume confirmation, and always keep risk management in mind.
