Least Square MA VertexFX Indicator

The Least Square MA is a moving average based indicator that employs least-squares regression model.
Using the closing prices, we calculate the least squares co-efficient over the recent R_PERIOD candles. The co-efficients are calculated using linear weighted moving average.
The Least Square MA builds the price curve which is closest to all the candle closes over the R_PERIOD. Hence it reduces the lag efficiently.
