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 CURB 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 26, 2026
End date: February 27, 2026
a = 0.4541
b = 0.0056
s = 0.0099
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0056) – 1
= 660.54%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0099) – 1
= 4.06%

Top border of price channel:
Exp(Y332)
= Exp(a + b × X332 + 2 × s)
= Exp(a + b × 487 + 2 × s)
= Exp(0.4541 + 0.0056 × 487 + 2 × 0.0099)
= Exp(3.1810)
= $24.07
Bottom border of price channel:
Exp(Y332)
= Exp(a + b × X332 – 2 × s)
= Exp(a + b × 487 – 2 × s)
= Exp(0.4541 + 0.0056 × 487 – 2 × 0.0099)
= Exp(3.1412)
= $23.13

Exp(Y355)
= Exp(a + b × X355 + 2 × s)
= Exp(a + b × 519 + 2 × s)
= Exp(0.4541 + 0.0056 × 519 + 2 × 0.0099)
= Exp(3.3589)
= $28.76
Bottom border of price channel:
Exp(Y355)
= Exp(a + b × X355 – 2 × s)
= Exp(a + b × 519 – 2 × s)
= Exp(0.4541 + 0.0056 × 519 – 2 × 0.0099)
= Exp(3.3191)
= $27.64
