Top and Bottom Expansion
This indicator calculates the distance between the top and the bottom. This distance is projected equally above the top and below the bottom. The distance used between the top and bottom is called the reference channel and the first distance above or below the reference channel is called the neutral zone. Buying and selling occurs when the support is lost or the resistance breaks in the neutral zone. It is possible to follow trends through this indicator and maintain a safe position with stop.
