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 DRH 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: February 10, 2021
End date: December 7, 2023

a = 2.3633

b = -0.0002

s = 0.0653

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0002) – 1
= -7.30%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0653) – 1
= 29.85%

Top border of price channel:

Exp(Y307)
= Exp(a + b × X307 + 2 × s)
= Exp(a + b × 448 + 2 × s)
= Exp(2.3633 + -0.0002 × 448 + 2 × 0.0653)
= Exp(2.4009)
= $11.03

Bottom border of price channel:

Exp(Y307)
= Exp(a + b × X307 – 2 × s)
= Exp(a + b × 448 – 2 × s)
= Exp(2.3633 + -0.0002 × 448 – 2 × 0.0653)
= Exp(2.1397)
= $8.50

Top border of price channel:

Exp(Y1,018)
= Exp(a + b × X1,018 + 2 × s)
= Exp(a + b × 1,478 + 2 × s)
= Exp(2.3633 + -0.0002 × 1,478 + 2 × 0.0653)
= Exp(2.1871)
= $8.91

Bottom border of price channel:

Exp(Y1,018)
= Exp(a + b × X1,018 – 2 × s)
= Exp(a + b × 1,478 – 2 × s)
= Exp(2.3633 + -0.0002 × 1,478 – 2 × 0.0653)
= Exp(1.9259)
= $6.86
