Traders should look for the crossover moments of the green and red lines. When the green line crosses under the red represents a buy signal or market gaining momentum for purchase. The blue bars show when the momentum loses strength and starts a reverse trend that it is only confirmed with the next bars crossover. When the blue line interrupts the sequence it is an opportunity to exit the trade. This indicator works with indexes or currencies, the ^ Period ^ parameter is used to count the previous bars. When the market varies greatly the best analysis is to increase the bars and the value of the ^ Period ^ to avoid interpreting noise in the price.
