Buzzer is a modification on moving average to identify trend direction. Normal moving average strategy is to buy when price is above moving average and sell when price is below moving average. However Buzzer works in a different manner. When the buzzer line is rising or flat after a rise, it indicates up trend and when buzzer line is declining or flat after a decline, it indicates down trend. The trading strategy with buzzer line is to buy when the line begins to rise and sell when the line begins to decline.
