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: August 26, 2025
End date: February 3, 2026
a = 9.1315
b = -0.0015
s = 0.0315
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0015) – 1
= -41.18%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0315) – 1
= 13.41%

Top border of price channel:
Exp(Y1,130)
= Exp(a + b × X1,130 + 2 × s)
= Exp(a + b × 1,643 + 2 × s)
= Exp(9.1315 + -0.0015 × 1,643 + 2 × 0.0315)
= Exp(6.8056)
= $902.90
Bottom border of price channel:
Exp(Y1,130)
= Exp(a + b × X1,130 – 2 × s)
= Exp(a + b × 1,643 – 2 × s)
= Exp(9.1315 + -0.0015 × 1,643 – 2 × 0.0315)
= Exp(6.6797)
= $796.12

= Exp(6.5715)
= $714.46
Bottom border of price channel:
Exp(Y1,240)
