The average crossover element can be found in the indicators section:
With this indicator, we can choose two averages, with their respective candle periods, and also choose which type of average we want to use, with simple, exponential, smoothed, and linear weighted options.
In this case, we’ll set the first option to 20 periods for the moving average and the simple average type; while the second option will set the exponential average to 89 periods.
