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 VLO 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: March 13, 2024
End date: January 10, 2025
a = 6.4914
b = -0.0010
s = 0.0381
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0010) – 1
= -29.94%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0381) – 1
= 16.46%

Top border of price channel:
Exp(Y973)
= Exp(a + b × X973 + 2 × s)
= Exp(a + b × 1,413 + 2 × s)
= Exp(6.4914 + -0.0010 × 1,413 + 2 × 0.0381)
= Exp(5.1903)
= $179.53
Bottom border of price channel:
Exp(Y973)
= Exp(a + b × X973 – 2 × s)
= Exp(a + b × 1,413 – 2 × s)
= Exp(6.4914 + -0.0010 × 1,413 – 2 × 0.0381)
= Exp(5.0380)
= $154.16

Top border of price channel:
Exp(Y1,181)
= Exp(a + b × X1,181 + 2 × s)
= Exp(a + b × 1,716 + 2 × s)
= Exp(6.4914 + -0.0010 × 1,716 + 2 × 0.0381)
= Exp(4.8950)
= $133.62
Bottom border of price channel:
Exp(Y1,181)
= Exp(a + b × X1,181 – 2 × s)
= Exp(a + b × 1,716 – 2 × s)
= Exp(6.4914 + -0.0010 × 1,716 – 2 × 0.0381)
= Exp(4.7426)
= $114.74
