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 NEU 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: January 2, 2025
End date: October 8, 2025
a = 2.9059
b = 0.0021
s = 0.0335
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0021) – 1
= 118.97%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0335) – 1
= 14.35%

Top border of price channel:
Exp(Y1,038)
= Exp(a + b × X1,038 + 2 × s)
= Exp(a + b × 1,511 + 2 × s)
= Exp(2.9059 + 0.0021 × 1,511 + 2 × 0.0335)
= Exp(6.2176)
= $501.49
Bottom border of price channel:
Exp(Y1,038)
= Exp(a + b × X1,038 – 2 × s)
