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 ED 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: March 2, 2022
End date: July 23, 2024

a = 4.4094

b = 0.0000

s = 0.0416

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0000) – 1
= 1.55%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0416) – 1
= 18.12%

March 2, 2022 calculations

Top border of price channel:

Exp(Y418)
= Exp(a + b × X418 + 2 × s)
= Exp(a + b × 604 + 2 × s)
= Exp(4.4094 + 0.0000 × 604 + 2 × 0.0416)
= Exp(4.5181)
= $91.66

Bottom border of price channel:

Exp(Y418)
= Exp(a + b × X418 – 2 × s)
= Exp(a + b × 604 – 2 × s)
= Exp(4.4094 + 0.0000 × 604 – 2 × 0.0416)
= Exp(4.3516)
= $77.60

July 23, 2024 calculations

Top border of price channel:

Exp(Y1,018)
= Exp(a + b × X1,018 + 2 × s)
= Exp(a + b × 1,478 + 2 × s)
= Exp(4.4094 + 0.0000 × 1,478 + 2 × 0.0416)
= Exp(4.5549)
= $95.09

Bottom border of price channel:

Exp(Y1,018)
= Exp(a + b × X1,018 – 2 × s)
= Exp(a + b × 1,478 – 2 × s)
= Exp(4.4094 + 0.0000 × 1,478 – 2 × 0.0416)
= Exp(4.3884)
= $80.51
