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 GWW 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 11, 2024
End date: December 10, 2025
a = 7.5733
b = -0.0004
s = 0.0448
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0004) – 1
= -13.53%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0448) – 1
= 19.64%

Exp(Y957)
= Exp(a + b × X957 + 2 × s)
= Exp(a + b × 1,390 + 2 × s)
= Exp(7.5733 + -0.0004 × 1,390 + 2 × 0.0448)
= Exp(7.1095)
= $1,223.50
Bottom border of price channel:
Exp(Y957)
= Exp(a + b × X957 – 2 × s)
= Exp(a + b × 1,390 – 2 × s)
= Exp(7.5733 + -0.0004 × 1,390 – 2 × 0.0448)
= Exp(6.9301)
= $1,022.65
