I've edited the normal Bill Williams Alligator indicator to have a color fill that indicates the trend. There is a percentage range filter which checks if the 2 outer lines are enough far away from eachother to indicate a trend. The indicator also checks if the lines are below or above eachother in the right order as a last check to confirm Trend

Cleaned up the code and removed the other indicator from the chart which was visible on the first publish.
