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 DTE 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 10, 2023
End date: October 30, 2025
a = 4.0370
b = 0.0005
s = 0.0342
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0005) – 1
= 21.73%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0342) – 1
= 14.67%

Top border of price channel:
Exp(Y618)
= Exp(a + b × X618 + 2 × s)
= Exp(a + b × 896 + 2 × s)
= Exp(4.0370 + 0.0005 × 896 + 2 × 0.0342)
= Exp(4.5881)
= $98.31
Bottom border of price channel:
Exp(Y618)
= Exp(a + b × X618 – 2 × s)
= Exp(a + b × 896 – 2 × s)
= Exp(4.0370 + 0.0005 × 896 – 2 × 0.0342)
= Exp(4.4512)
= $85.73

= Exp(5.0255)
= $152.24
Bottom border of price channel:
Exp(Y1,176)
= Exp(a + b × X1,176 – 2 × s)
= Exp(a + b × 1,708 – 2 × s)
= Exp(4.0370 + 0.0005 × 1,708 – 2 × 0.0342)
= Exp(4.8886)
