Aroon is an oscillator.
It helps determine the direction and strength of a trend, as well as find the points of its reversal.
It’s made up of two lines: the blue Aroon Up line and the yellow Aroon Down line.
These lines move between values of 0 and 100, and periodically cross the levels of 70, 50 and 30.
The lines of the oscillator crossing these levels is a signal to open a trade.
