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 16, 2021
End date: December 6, 2023

a = 2.3953

b = -0.0002

s = 0.0650

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0002) – 1
= -7.42%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0650) – 1
= 29.67%

February 16, 2021 calculations

Top border of price channel:

Exp(Y392)
= Exp(a + b × X392 + 2 × s)
= Exp(a + b × 571 + 2 × s)
= Exp(2.3953 + -0.0002 × 571 + 2 × 0.0650)
= Exp(2.4046)
= $11.07

Bottom border of price channel:

Exp(Y392)
= Exp(a + b × X392 – 2 × s)
= Exp(a + b × 571 – 2 × s)
= Exp(2.3953 + -0.0002 × 571 – 2 × 0.0650)
= Exp(2.1448)
= $8.54

Top border of price channel:

Exp(Y1,099)
= Exp(a + b × X1,099 + 2 × s)
= Exp(a + b × 1,594 + 2 × s)
= Exp(2.3953 + -0.0002 × 1,594 + 2 × 0.0650)
= Exp(2.1885)
= $8.92

Bottom border of price channel:

Exp(Y1,099)
= Exp(a + b × X1,099 – 2 × s)
= Exp(a + b × 1,594 – 2 × s)
= Exp(2.3953 + -0.0002 × 1,594 – 2 × 0.0650)
= Exp(1.9287)
= $6.88
