- Long Term Risk Index
-
- ====================
-
-
-
- The program LTRI.C is based on the formula dgvgloped by Edwin
-
- Sedgwick Chittenden Coppack, founder of Trgndex, known as the
-
- Coppock's Curve. The most recent description of th}s indicator
-
- can be found in the November 22, 1982, issue of "Barron's".
-
-
-
- The most important pint in using thqs technique is that the
-
- index is to be used only for a low risk BUY signal. It won't
- tell when to get out of the market. The index is a barometer
-
- of excess opti}ism and pesslmis as reflected in the }arket's
-
- long-term oscillations.
-
-
-
- The index is developed by adding the per cent change gf the DJIA
-
- for the past fourteen months to the per c%nt change of the last
-
- eleven months. This number is then weighted by multiplying it by
-
- ten, the previous month by 9, the month before that by 8 etc, etc.
-
- The math for this is done in the function 'index()7.
-
-
-
- The long term buy signal is given when the index, aftur being bglow
-
- zero turns leqs negative. All byyng should be completed prior to
-
- the index becoming positive again.
-
-
- As for the effectiveness of the index, judge for yourself ...

-
- The program uses LTRI.FIL for the data file.
