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: May 7, 2024
a = 1.2179
b = 0.0010
s = 0.0865
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0010) – 1
= 42.74%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0865) – 1
= 41.32%

Top border of price channel:
Exp(Y860)
= Exp(a + b × X860 + 2 × s)
= Exp(a + b × 1,246 + 2 × s)
= Exp(1.2179 + 0.0010 × 1,246 + 2 × 0.0865)
= Exp(2.6055)
= $13.54
Bottom border of price channel:
Exp(Y860)
= Exp(a + b × X860 – 2 × s)
= Exp(a + b × 1,246 – 2 × s)
= Exp(1.2179 + 0.0010 × 1,246 – 2 × 0.0865)
= Exp(2.2596)
= $9.58

Exp(Y1,258)
= Exp(a + b × X1,258 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(1.2179 + 0.0010 × 1,826 + 2 × 0.0865)
= Exp(3.1709)
= $23.83
Bottom border of price channel:
Exp(Y1,258)
= Exp(a + b × X1,258 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(1.2179 + 0.0010 × 1,826 – 2 × 0.0865)
= Exp(2.8250)
= $16.86
