The lengths are Fibonacci numbers starting from 5 and ending with 377.
The colors indicate the length of the moving average, green for the shortest and purple for the longest.
The zones between consecutive EMA's (e.g. 5 and 8 ) are market according to the color of the greater one in value.
By default the script plots values for the current time frame, but supports custom time frames.
I'm releasing this script with an open visibility. Feel free to suggest improvements!
