Most traders do not put all the pieces of the puzzle together when learning and using technical analysis. Let's talk about topping and bottoming tails. Simply put, a bottoming tail is a bullish signal and a topping tail is bearish. A bottoming tail MUST occur at the lows of a chart. This means that no point on the chart in recent history can be lower. Next, the tail must be substantial, not just a little thing barely seen by the eye. Additionally, the close of the candle must be in the upper 25% when measuring from the lows to the highs. If all these factors match up, you may have a bottoming tail. The same things apply for a topping tail.
