Any trader can quickly identify a Dragonfly from the chart because it is a T-shaped pattern.Its lower shadow is extremely long, whereas the open, close, and high tend to be at the same level.The primary requirement for ideal dragonflies is for the open and close to be extremely close to one another. However, ideal dragonflies are extremely rare.Additionally, the high must coincide with the close or, at the very least, cast a brief upper shadow.
