Is there a specific EMA crossover strategy that is commonly used?

A commonly used EMA crossover strategy involves the crossover of a shorter EMA (e.g., 9-period) and a longer EMA (e.g., 21-period).

A bullish signal occurs when the shorter EMA crosses above the longer EMA, while a bearish signal occurs when the shorter EMA crosses below the longer EMA.
