The goal of many indicators is to determine the true trend of the
security in the presence of noise.
MS has pre-programmed 3 indicators that fit price to a straight line:
Lin Reg Ind
Lin Reg Slope
Lin Reg Trendline
My observation was that prices rarely move in a straight line, much
more common is that the price action is curved - like a section of a
parabola. (A straight line is a special case of a parabola with the
x^2 term equal to zero)
After programming the fit to a quadratic, I found that it more
accurately determined the markets trend, with significantly less lag
than a fit to a straight line.
After normalizing prices to $100 and calculating the first derivative
of the quadratic at the most recent bar, I found that I had a
accurate, fast responding ranking system that worked well with ETF's.
My portfolio of the top 4 ranked ETF's (out of a universe of 20 ) is
up 22% YTD with a max drawdown of 6%.
I trade the above system in 5 accounts for my family. I am a private
investor - nothing for sale - no website.
