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 CLH 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: June 12, 2024
End date: November 17, 2025
a = 5.6004
b = -0.0001
s = 0.0697
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0001) – 1
= -3.68%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0697) – 1
= 32.14%

Top border of price channel:
Exp(Y895)
= Exp(a + b × X895 + 2 × s)
= Exp(a + b × 1,302 + 2 × s)
= Exp(5.6004 + -0.0001 × 1,302 + 2 × 0.0697)
= Exp(5.6060)
= $272.07
Bottom border of price channel:
Exp(Y895)
= Exp(a + b × X895 – 2 × s)
= Exp(a + b × 1,302 – 2 × s)
= Exp(5.6004 + -0.0001 × 1,302 – 2 × 0.0697)
= Exp(5.3273)
= $205.89
