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 WM 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: April 7, 2021
End date: December 26, 2023
a = 4.8582
b = 0.0002
s = 0.0481
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0002) – 1
= 6.83%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0481) – 1
= 21.24%

Top border of price channel:
Exp(Y255)
= Exp(a + b × X255 + 2 × s)
= Exp(a + b × 371 + 2 × s)
= Exp(4.8582 + 0.0002 × 371 + 2 × 0.0481)
= Exp(5.0217)
= $151.67
Bottom border of price channel:
Exp(Y255)
= Exp(a + b × X255 – 2 × s)
= Exp(a + b × 371 – 2 × s)
= Exp(4.8582 + 0.0002 × 371 – 2 × 0.0481)
= Exp(4.8292)
= $125.11

Top border of price channel:
Exp(Y940)
= Exp(a + b × X940 + 2 × s)
= Exp(a + b × 1,364 + 2 × s)
= Exp(4.8582 + 0.0002 × 1,364 + 2 × 0.0481)
= Exp(5.2016)
= $181.56
Bottom border of price channel:
Exp(Y940)
= Exp(a + b × X940 – 2 × s)
= Exp(a + b × 1,364 – 2 × s)
= Exp(4.8582 + 0.0002 × 1,364 – 2 × 0.0481)
= Exp(5.0090)
= $149.76
