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 CB 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: August 23, 2024
End date: November 10, 2025

a = 5.6583

b = 0.0000

s = 0.0305

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0000) – 1
= -0.59%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0305) – 1
= 13.00%

Top border of price channel:

Exp(Y939)
= Exp(a + b × X939 + 2 × s)
= Exp(a + b × 1,365 + 2 × s)
= Exp(5.6583 + 0.0000 × 1,365 + 2 × 0.0305)
= Exp(5.6972)
= $298.04

Bottom border of price channel:

Exp(Y939)
= Exp(a + b × X939 – 2 × s)
= Exp(a + b × 1,365 – 2 × s)
= Exp(5.6583 + 0.0000 × 1,365 – 2 × 0.0305)
= Exp(5.5751)
= $263.76

Top border of price channel:

Exp(Y1,243)
= Exp(a + b × X1,243 + 2 × s)
= Exp(a + b × 1,809 + 2 × s)
= Exp(5.6583 + 0.0000 × 1,809 + 2 × 0.0305)
= Exp(5.6900)
= $295.90

Bottom border of price channel:

Exp(Y1,243)
= Exp(a + b × X1,243 – 2 × s)
= Exp(a + b × 1,809 – 2 × s)
= Exp(5.6583 + 0.0000 × 1,809 – 2 × 0.0305)
= Exp(5.5678)
= $261.87
