Double Exponential SmoothingSingle Exponential Smoothing ( ema ) does not excel in following the data when there is a trend. This situation can be improved by the introduction of a second equation with a second constant gamma .
The gamma constant cant be lower than 0 and cant be greater than 1, higher values of gamma create less lag while preserving smoothness.Higher values of length must be followed by higher values of gamma in order to keep the lag low.
The first smoothing part consist of a classic ema but we add s-s1 to the previous smoothed value, this will help decrease lag.The second smoothing part then updates the trend, which is expressed as the difference between the last two values.
3 Moving Average ExponentialSince I noticed there was no Script with actually 3 EMA together (all the ones I found said it was Exponential, but actually was Simple), i created this one.
The lengths, 17 72 305, are based on the phi cube theory, introduced by Bo Williams. The slow length (305) indicate a likely strong support/resistance and the region between the fast and medium lengths (17, 72) indicate where the price tends to return after a boost or little diversion from the price average.
Four Exponential Moving Averages by B00m2tM00nAfter little research I couldn't find a simple 4EMA ribbon that bled when necessary.
Admittedly, nothing new here, use where you think appropriate.
Suggestions welcome!
Fibonacci Exponential Moving Averages ( EMA )Here you can have 4 EMA on one indicator. The inputs are for 8, 13, 21 and 55 previous open&close which are from Fibonacci sequence.
How to : To use the script, click on "Add to Favourite Scripts", then load the script from Indicators on the Chart.
Fibonacci Exponential Moving Averages ( EMA )
Have 8, 13, 21 and 55 EMA on one indicator ! enjoy :)

TEMA - Triple Moving Averages (50,100,200)Three Moving Averages in a single indicator, very useful if you are a free user and want to save some indicator slots.
Enjoy it :)
