Definition
The bars-based advance/decline ratio indicator shows the number of bars that closed higher compared to the number of bars that closed lower for the current symbol and the specified length. The indicator calculates the number of green and red bars for the last several bars and divides the first number by the second. The ratio can be used to analyze the historical performance of the current symbol in the specified window: higher values mean the prices consistently traded up and vice versa.
