Indicator - Slope
of a Line
rev.
01/06/97
The following custom formula returns the slope of
a line. For example, this formula returns the
slope of a 14 day run of the security's closing
prices.
| (
(14 * (Sum(Cum( 1 ) * C ,14 ) ) ) -
(Sum(Cum( 1 ) ,14 ) * (Sum( C ,14)
) ) ) / ( (14 * Sum(Pwr (Cum( 1 ) ,2 ) ,14
) ) - Pwr(Sum(Cum( 1 ) ,14 ) ,2 ) ) |
To apply this to different lines you would replace
C with the desired syntax for the line. For
example the slope of a 25 period simple moving
average would be:
| (
( Sum(Cum(1) * Mov(C,25,S),14) ) -
(Sum(Cum(1),14) * Sum(Mov(C,25,S),14)
/ 14) ) / ( (Sum(Power(Cum(1),2),14) ) -
(Power(Sum(Cum(1),14),2) / 14) ) |
You could also make this a universal formula by
using the P variable. You could then plot
the formula on top of any line.
| (
(14*(Sum(Cum(1)*P,14) ) ) -
Sum(Cum(1),14)*(Sum(P,14 ) ) ) / (
(14*Sum(Pwr(Cum(1),2 ),14 )
)-Pwr(Sum(Cum(1),14),2 ) ) |
