Double Bottom
A double bottom is a bullish reversal pattern where price tests the same low twice and then breaks above the high between the troughs.
Two lows at about the same level suggest sellers have run out of force at that price. Confirmation comes when the close breaks above the peak between the lows, and the pattern's height gives a target.
A second low on lower volume than the first is read as healthier. See the double bottom hub for coins forming it now and how it has performed.
