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 VSH 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: May 25, 2023
End date: April 2, 2025
a = 4.1023
b = -0.0007
s = 0.0664
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0007) – 1
= -23.18%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0664) – 1
= 30.40%
May 25, 2023 calculations
Top border of price channel:
Exp(Y773)
= Exp(a + b × X773 + 2 × s)
= Exp(a + b × 1,120 + 2 × s)
= Exp(4.1023 + -0.0007 × 1,120 + 2 × 0.0664)
= Exp(3.4260)
= $30.75
Bottom border of price channel:
Exp(Y773)
= Exp(a + b × X773 – 2 × s)
= Exp(a + b × 1,120 – 2 × s)
= Exp(4.1023 + -0.0007 × 1,120 – 2 × 0.0664)
= Exp(3.1606)
= $23.58

Top border of price channel:
Exp(Y1,237)
= Exp(a + b × X1,237 + 2 × s)
= Exp(a + b × 1,798 + 2 × s)
= Exp(4.1023 + -0.0007 × 1,798 + 2 × 0.0664)
= Exp(2.9363)
= $18.85
Bottom border of price channel:
Exp(Y1,237)
= Exp(a + b × X1,237 – 2 × s)
= Exp(a + b × 1,798 – 2 × s)
= Exp(4.1023 + -0.0007 × 1,798 – 2 × 0.0664)
= Exp(2.6709)
= $14.45
