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 WHD 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: September 17, 2024
End date: July 2, 2025
a = 7.0938
b = -0.0019
s = 0.1092
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0019) – 1
= -49.44%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1092) – 1
= 54.77%

Top border of price channel:
Exp(Y1,057)
= Exp(a + b × X1,057 + 2 × s)
= Exp(a + b × 1,534 + 2 × s)
= Exp(7.0938 + -0.0019 × 1,534 + 2 × 0.1092)
= Exp(4.4461)
= $85.29
Bottom border of price channel:
Exp(Y1,057)
= Exp(a + b × X1,057 – 2 × s)
= Exp(a + b × 1,534 – 2 × s)
= Exp(7.0938 + -0.0019 × 1,534 – 2 × 0.1092)
= Exp(4.0093)
= $55.11
