The Variable Length Moving Average was created by George R. Arrington Ph.D. (Stocks & Commodities V. 9:6 (219-223)) and I'm really loving this indicator. It is a great moving average that hugs the price very closely and it is fully adjustable to your needs. It detects signals extremely well and I have color coded the moving average line to make it very easy to interpret.
This is not to be confused with the Variable Moving Average created by Tushar S. Chande and as of now I haven't seen any other script for this moving average out there yet.
Please let me know if you would like me to write any other scripts for indicators you would like to see!
