Ascending and descending triangles

Q: What is the directional bias of an ascending triangle?

Right. Higher lows mean buyers are increasingly aggressive while sellers hold the same level. Pressure builds upward.

Pressure building against a flat wall

An ascending triangle is one of the cleanest continuation patterns in technical analysis. The shape is simple. The top boundary is a flat horizontal line. Price keeps stopping at the same high again and again. The bottom boundary is a rising trendline drawn across higher lows. Each pullback bottoms a little higher than the last. Buyers are getting more aggressive. Sellers are holding the same level. The shape is a triangle pinched into the upper right corner of a chart.

Wick saysAn ascending triangle has a flat top and rising lows, which gives a bullish lean.

The directional bias is bullish. Not guaranteed, but bullish. The reasoning is mechanical. Demand is escalating into a fixed supply zone. Sellers have to absorb more buying volume each time price tests the top. Eventually either the sellers run out of orders at that level or buyers get impatient and push through. Both outcomes resolve upward. That is why most textbooks describe ascending triangles as bullish continuation patterns.

A descending triangle is the mirror image. The bottom is a flat horizontal line. Price keeps stopping at the same low again and again. The top boundary is a falling trendline drawn across lower highs. Each rally fails a little lower than the last. Sellers are getting more aggressive. Buyers are holding the same level. The directional bias is bearish. Same mechanical reasoning, flipped. Supply is escalating into a fixed demand floor.

Wick saysBias is a guess, not destiny, so the breakout direction is what counts.

A practical detail. The flat boundary in either pattern needs at least two clean touches to be drawn legitimately. Same for the diagonal boundary. Two touches define a line. Three confirm it. If you find yourself bending a trendline to fit candle wicks just to get the triangle to work, you are forcing the pattern. A clean triangle is one you can draw without negotiating with the chart.

Wick saysDraw a triangle only with two clean touches per side, never by bending lines.

Recap: ascending triangle is flat top plus rising bottom, bullish bias. Descending triangle is flat bottom plus falling top, bearish bias. Both need a clean breakout to act on. Bias is a hypothesis, not a guarantee. Two clean touches on each boundary is the minimum standard for the pattern to be real, and you should never bend a trendline to fit candle wicks just to make the geometry work.
