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 HFWA 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: July 1, 2022
End date: November 30, 2023

a = 4.8835

b = -0.0013

s = 0.1458

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0013) – 1
= -38.12%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1458) – 1
= 79.16%

July 1, 2022 calculations

Top border of price channel:

Exp(Y786)
= Exp(a + b × X786 + 2 × s)
= Exp(a + b × 1,138 + 2 × s)
= Exp(4.8835 + -0.0013 × 1,138 + 2 × 0.1458)
= Exp(3.6785)
= $39.59

Bottom border of price channel:

Exp(Y786)
= Exp(a + b × X786 – 2 × s)
= Exp(a + b × 1,138 – 2 × s)
= Exp(4.8835 + -0.0013 × 1,138 – 2 × 0.1458)
= Exp(3.0954)
= $22.10

November 30, 2023 calculations

Top border of price channel:

Exp(Y1,142)
= Exp(a + b × X1,142 + 2 × s)
= Exp(a + b × 1,655 + 2 × s)
= Exp(4.8835 + -0.0013 × 1,655 + 2 × 0.1458)
= Exp(2.9986)
= $20.06

Bottom border of price channel:

Exp(Y1,142)
= Exp(a + b × X1,142 – 2 × s)
= Exp(a + b × 1,655 – 2 × s)
= Exp(4.8835 + -0.0013 × 1,655 – 2 × 0.1458)
= Exp(2.4155)
= $11.19
