//Linear Regression Line with 2 Standard Deviation Channels Plotted Above and Below
//The original was written by Patrick Hargus, with critical hints from Marcin Gorzynski, Amibroker.com Technical Support
//Wysiwyg coded the angle in degrees part
//I modified the original Linear Regression code so that the line will change color based on the degree of the Linear Regression slope.
//I combine this with my trading system.
//When my system gives an entry signal I look at the Linear Regression Line and I will only take long positions if the Linear Regression line is green and the entry price is below the LR line.
//When my system gives an entry signal I look at the Linear Regression Line and I will only take short positions if the Linear Regression line is red and the entry price is above the LR line.
//It is usefull for filtering out lower probability trades.

hi
THE SYSTEM IS MAMA POSITIONAL SYSTEM.

the afl uses MAMA and FAMA.
BUY WHEN MAMA CROSSES FAMA
SELL WHEN FAMA CROSSES MAMA
THE Crossover for buy to occur near bottom two regression lines while sell occurs near top 2 regression lines.
it is like sell on down cross near resistance and buy on upcross near support line.
MAMA is MESA adaptive moving average.
FAMA is following adaptive moving average that follows MAMA.
MAMA is a moving average that adapts to price movement in an entirely new and unique way.
MAMA is called mother of adaptive moving averages.

can i use this for positional? which time frame is best?
This one is very easy to answer you. Yes it can.
Why ? Because it is printed on the top left of the chart "MAMA Positional System" in Post #1
The time frame shown is hourly.

The Author posted here show Daily timeframe.
http://www.wisestocktrader.com/indicators/149-mama-positional-system-v1-0



Definition of 'Position Trader'
A type of stock trader who holds a position for the long term (from months to years). Long-term traders are not concerned with short-term fluctuations because they believe that their long-term investment horizons will smooth these out.


So it obvious that the best timeframe to trade is daily.
