Element that works with information about the Price and the moving average. The element will give the signal when there is a cross, either upwards or downwards, of the average with respect to the price at that time. To know how the moving average works, visit this post.
There will be a bullish signal when the price crosses upwards the average, since it will be considered as a bullish movement of the market. Otherwise, it will be a bearish signal
The fast average crossed upwards can give a buying or a selling signal (by default, buying)
The fast average crossed downwards can give a selling or a buying signal (by default, selling)
The moving averages can be set up according to period (fast and slow), the type of moving average (simple, exponential…) and the timeframe
