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 AORT 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: October 5, 2022
End date: February 24, 2025
a = 1.4030
b = 0.0012
s = 0.0851
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0012) – 1
= 54.74%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0851) – 1
= 40.53%

Top border of price channel:
Exp(Y568)
= Exp(a + b × X568 + 2 × s)
= Exp(a + b × 821 + 2 × s)
= Exp(1.4030 + 0.0012 × 821 + 2 × 0.0851)
= Exp(2.5552)
= $12.87
Bottom border of price channel:
Exp(Y568)
= Exp(a + b × X568 – 2 × s)
= Exp(a + b × 821 – 2 × s)
= Exp(1.4030 + 0.0012 × 821 – 2 × 0.0851)
= Exp(2.2149)
= $9.16

Top border of price channel:
Exp(Y1,165)
= Exp(a + b × X1,165 + 2 × s)
= Exp(a + b × 1,694 + 2 × s)
= Exp(1.4030 + 0.0012 × 1,694 + 2 × 0.0851)
= Exp(3.5994)
= $36.58
Bottom border of price channel:
Exp(Y1,165)
= Exp(a + b × X1,165 – 2 × s)
= Exp(a + b × 1,694 – 2 × s)
= Exp(1.4030 + 0.0012 × 1,694 – 2 × 0.0851)
= Exp(3.2592)
= $26.03
