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 AROC 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: August 4, 2022
End date: March 3, 2025
a = 0.4420
b = 0.0016
s = 0.0803
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0016) – 1
= 80.72%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0803) – 1
= 37.86%
August 4, 2022 calculations
Top border of price channel:
Exp(Y589)
= Exp(a + b × X589 + 2 × s)
= Exp(a + b × 854 + 2 × s)
= Exp(0.4420 + 0.0016 × 854 + 2 × 0.0803)
= Exp(1.9872)
= $7.29
Bottom border of price channel:
Exp(Y589)
= Exp(a + b × X589 – 2 × s)
= Exp(a + b × 854 – 2 × s)
= Exp(0.4420 + 0.0016 × 854 – 2 × 0.0803)
= Exp(1.6661)
= $5.29

Top border of price channel:
Exp(Y1,234)
= Exp(a + b × X1,234 + 2 × s)
= Exp(a + b × 1,796 + 2 × s)
= Exp(0.4420 + 0.0016 × 1,796 + 2 × 0.0803)
= Exp(3.5144)
= $33.60
Bottom border of price channel:
Exp(Y1,234)
= Exp(a + b × X1,234 – 2 × s)
= Exp(a + b × 1,796 – 2 × s)
= Exp(0.4420 + 0.0016 × 1,796 – 2 × 0.0803)
= Exp(3.1933)
= $24.37
