To determine if the trend is statistically significant for a given x-period linear regression line,
plot the r-squared indicator and refer to the following table. This table shows the values of
r-squared required for a 95% confidence level at various time periods. If the r-squared value
is less than the critical values shown, you should assume that prices show no statistically
significant trend.
Number ofPeriods r-squaredCritical Value(95%confidence)

10 0.40

20 0.20
25 0.16
30 0.13
50 0.08
60 0.06
120 0.03
You may even consider opening a short-term position opposite the prevailing trend when you
observe r-squared rounding off at extreme levels. على سبيل المثال, if the slope is positive and
r-squared is above 0.80 and begins to turn down, you may consider selling or opening a short position.
There are numerous ways to use the linear regression outputs of r-squared and Slope in trading
أنظمة. For more detailed coverage, refer to the book The New Technical Trader by Tushar Chande
and Stanley Kroll.
