End Point Moving Average [EPMA]

The End Point Moving Average was introduced in the October 95 issue of Technical Analysis of Stocks &
Commodities in the article "The End Point Moving Average", by Patrick E. Lafferty.

The Time Series Forecast takes this value and the slope of the regression line to forecast the next day and then plots this forecasted price as today's value.

For interpretation refer to Mr. Lafferty's article.

Please note
From line 10 starts my personal experemental modifications to this script, all above is original formula by Patrick E. Lafferty.
