Triangles with a **flat side** are among the cleanest patterns because the flat line is a clear, tested level. Buyers or sellers keep hitting it, and eventually it gives way.

## Ascending triangle (bullish lean)

{{diagram:ascending-triangle}}

Price tests a **flat resistance** repeatedly while making **higher lows**. Buyers are stepping in earlier each time, and sellers are defending one price. Each retest weakens that ceiling.

**Trade plan:**

- **Entry:** a candle close above the flat resistance, or a retest of it as support.
- **Stop:** below the most recent higher low (or below the rising trendline).
- **Target:** project the triangle's height (distance from the first low to the resistance) up from the breakout.

## Descending triangle (bearish lean)

{{diagram:descending-triangle}}

Price tests a **flat support** repeatedly while making **lower highs**. Sellers are stepping in earlier, and buyers are defending one price. Each retest weakens that floor.

**Trade plan:**

- **Entry:** a candle close below the flat support, or a failed retest of it from below.
- **Stop:** above the most recent lower high (or above the falling trendline).
- **Target:** project the triangle's height down from the breakdown.

## Making them more reliable

1. **Count the touches.** Two on each line is the minimum; three or more on the flat line is better.
2. **Check the trend.** An ascending triangle inside an uptrend (continuation) is stronger than one at the end of a downtrend.
3. **Look at volume.** Contracting volume inside, expansion on the break.
4. **Mind the nearby levels.** A major resistance just above the breakout shortens your realistic target.

## Common mistakes

- Trading the pattern before it breaks.
- Treating a wick through the flat line as a breakout.
- Stops placed exactly at the obvious level, where stop-hunts happen. Give the stop some room.

## Key takeaways

- Ascending triangle: flat resistance, rising lows, bullish lean. Descending: flat support, falling highs, bearish lean.
- Enter on the closing break, stop on the other side of the last swing.
- Target the triangle height and manage risk. Educational only, not financial advice.

**Which way does an ascending triangle usually break?**
It leans bullish: a flat resistance with rising support suggests buyers are getting more aggressive. It can fail, so wait for a close above resistance.

**Do triangles work on all timeframes?**
Yes, the structure appears on all timeframes, but patterns on higher timeframes (H4, daily) carry more weight and produce fewer false signals than on very short timeframes.

**What volume pattern do you want to see?**
Volume usually contracts as the triangle forms and expands on the breakout. A breakout on weak volume is more likely to fail.
