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 PI 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: October 4, 2024
End date: February 3, 2025
a = 14.1373
b = -0.0051
s = 0.0518
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0051) – 1
= -84.43%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0518) – 1
= 23.00%

Top border of price channel:
Exp(Y1,175)
= Exp(a + b × X1,175 + 2 × s)
= Exp(a + b × 1,704 + 2 × s)
= Exp(14.1373 + -0.0051 × 1,704 + 2 × 0.0518)
= Exp(5.5579)
= $259.27
Bottom border of price channel:
Exp(Y1,175)
= Exp(a + b × X1,175 – 2 × s)
= Exp(a + b × 1,704 – 2 × s)
= Exp(14.1373 + -0.0051 × 1,704 – 2 × 0.0518)
= Exp(5.3509)
= $210.79

= Exp(a + b × X1,256 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(14.1373 + -0.0051 × 1,826 + 2 × 0.0518)
= Exp(4.9362)
= $139.24
Bottom border of price channel:
Exp(Y1,256)
= Exp(a + b × X1,256 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(14.1373 + -0.0051 × 1,826 – 2 × 0.0518)
= Exp(4.7292)
= $113.20
