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 WLY 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 12, 2023
End date: November 19, 2024

a = 1.1258

b = 0.0015

s = 0.0437

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0015) – 1
= 75.71%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0437) – 1
= 19.10%

October 12, 2023 calculations

Top border of price channel:

Exp(Y979)
= Exp(a + b × X979 + 2 × s)
= Exp(a + b × 1,422 + 2 × s)
= Exp(1.1258 + 0.0015 × 1,422 + 2 × 0.0437)
= Exp(3.4092)
= $30.24

Bottom border of price channel:

Exp(Y979)
= Exp(a + b × X979 – 2 × s)
= Exp(a + b × 1,422 – 2 × s)
= Exp(1.1258 + 0.0015 × 1,422 – 2 × 0.0437)
= Exp(3.2344)
= $25.39

November 19, 2024 calculations

Top border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(1.1258 + 0.0015 × 1,826 + 2 × 0.0437)
= Exp(4.0331)
= $56.43

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(1.1258 + 0.0015 × 1,826 – 2 × 0.0437)
= Exp(3.8583)
= $47.38

Secondary Trend

Start date: July 8, 2024
End date: November 19, 2024

a = 2.0561

b = 0.0010

s = 0.0357

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0010) – 1
= 45.40%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0357) – 1
= 15.36%

July 8, 2024 calculations

Top border of price channel:

Exp(Y1,162)
= Exp(a + b × X1,162 + 2 × s)
= Exp(a + b × 1,692 + 2 × s)
= Exp(2.0561 + 0.0010 × 1,692 + 2 × 0.0357)
= Exp(3.8627)
= $47.59

Bottom border of price channel:

Exp(Y1,162)
= Exp(a + b × X1,162 – 2 × s)
= Exp(a + b × 1,692 – 2 × s)
= Exp(2.0561 + 0.0010 × 1,692 – 2 × 0.0357)
= Exp(3.7198)
= $41.26

November 19, 2024 calculations

Top border of price channel:

= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(2.0561 + 0.0010 × 1,826 + 2 × 0.0357)
= Exp(4.0001)
= $54.60

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
