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 CLH 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: October 8, 2024
End date: March 31, 2025

a = 8.1937

b = -0.0016

s = 0.0456

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0016) – 1
= -43.82%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0456) – 1
= 19.99%

October 8, 2024 calculations

Top border of price channel:

Exp(Y1,137)
= Exp(a + b × X1,137 + 2 × s)
= Exp(a + b × 1,651 + 2 × s)
= Exp(8.1937 + -0.0016 × 1,651 + 2 × 0.0456)
= Exp(5.6770)
= $292.07

Bottom border of price channel:

Exp(Y1,137)
= Exp(a + b × X1,137 – 2 × s)
= Exp(a + b × 1,651 – 2 × s)
= Exp(8.1937 + -0.0016 × 1,651 – 2 × 0.0456)
= Exp(5.4948)
= $243.42

March 31, 2025 calculations

Top border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(8.1937 + -0.0016 × 1,825 + 2 × 0.0456)
= Exp(5.4022)
= $221.88

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(8.1937 + -0.0016 × 1,825 – 2 × 0.0456)
= Exp(5.2199)
= $184.92
