Some chart shapes are so common that people gave them names. The easiest to spot are the double bottom (W) and double top (M) — they look just like the letters.

PriceExample

Double bottom — price touches the floor twice and turns up, like a W. The dashed line is the neckline.

When the price tests the same floor twice, more people think 'it doesn't want to go lower' and start buying. That's why double bottoms often appear near the end of a downtrend.

PriceExample

Double top — price knocks on the ceiling twice and turns down, like an M.
