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 CB 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: July 26, 2024
End date: November 10, 2025
a = 5.5955
b = 0.0000
s = 0.0317
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0000) – 1
= 0.74%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0317) – 1
= 13.51%

Top border of price channel:
Exp(Y890)
= Exp(a + b × X890 + 2 × s)
= Exp(a + b × 1,292 + 2 × s)
= Exp(5.5955 + 0.0000 × 1,292 + 2 × 0.0317)
= Exp(5.6851)
= $294.45
Bottom border of price channel:
Exp(Y890)
= Exp(a + b × X890 – 2 × s)
= Exp(a + b × 1,292 – 2 × s)
= Exp(5.5955 + 0.0000 × 1,292 – 2 × 0.0317)
= Exp(5.5584)
= $259.39

Top border of price channel:
Exp(Y1,214)
= Exp(a + b × X1,214 + 2 × s)
= Exp(a + b × 1,764 + 2 × s)
= Exp(5.5955 + 0.0000 × 1,764 + 2 × 0.0317)
= Exp(5.6947)
= $297.28
Bottom border of price channel:
Exp(Y1,214)
= Exp(a + b × X1,214 – 2 × s)
= Exp(a + b × 1,764 – 2 × s)
= Exp(5.5955 + 0.0000 × 1,764 – 2 × 0.0317)
= Exp(5.5679)
= $261.89
