Linear Regression Model
Model equation:
Yi = α + β × Xi + εi
Top border of price channel:
Exp(Yi) = Exp(a + b × Xi + 2 × s)
Bottom border of price channel:
Exp(Yi) = Exp(a + b × Xi – 2 × s)
where:
i - observation number
Yi - natural logarithm of RPM price
Xi - time index, 1 day interval
σ - standard deviation of εi
a - estimator of α
b - estimator of β
s - estimator of σ
Exp() - calculates the exponent of e
Primary Trend
Start date: November 6, 2024
End date: April 29, 2025
a = 7.3870
b = -0.0015
s = 0.0360
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0015) – 1
= -41.91%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0360) – 1
= 15.48%

Top border of price channel:
Exp(Y1,138)
= Exp(a + b × X1,138 + 2 × s)
= Exp(a + b × 1,651 + 2 × s)
= Exp(7.3870 + -0.0015 × 1,651 + 2 × 0.0360)
= Exp(5.0021)
= $148.72
Bottom border of price channel:
Exp(Y1,138)
= Exp(a + b × X1,138 – 2 × s)
= Exp(a + b × 1,651 – 2 × s)
= Exp(7.3870 + -0.0015 × 1,651 – 2 × 0.0360)
= Exp(4.8581)
= $128.78

= Exp(7.3870 + -0.0015 × 1,825 + 2 × 0.0360)
= Exp(4.7431)
= $114.79
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(7.3870 + -0.0015 × 1,825 – 2 × 0.0360)
= Exp(4.5991)
= $99.40
