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: March 9, 2023
End date: May 21, 2025

a = 2.9188

b = 0.0005

s = 0.1070

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0005) – 1
= 21.78%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1070) – 1
= 53.41%

March 9, 2023 calculations

Top border of price channel:

Exp(Y600)
= Exp(a + b × X600 + 2 × s)
= Exp(a + b × 871 + 2 × s)
= Exp(2.9188 + 0.0005 × 871 + 2 × 0.1070)
= Exp(3.6029)
= $36.70

Bottom border of price channel:

Exp(Y600)
= Exp(a + b × X600 – 2 × s)
= Exp(a + b × 871 – 2 × s)
= Exp(2.9188 + 0.0005 × 871 – 2 × 0.1070)
= Exp(3.1749)
= $23.93

May 21, 2025 calculations

Top border of price channel:

Exp(Y1,152)
= Exp(a + b × X1,152 + 2 × s)
= Exp(a + b × 1,675 + 2 × s)
= Exp(2.9188 + 0.0005 × 1,675 + 2 × 0.1070)
= Exp(4.0369)
= $56.65

Bottom border of price channel:

Exp(Y1,152)
= Exp(a + b × X1,152 – 2 × s)
= Exp(a + b × 1,675 – 2 × s)
= Exp(2.9188 + 0.0005 × 1,675 – 2 × 0.1070)
= Exp(3.6089)
= $36.93

Secondary Trend

Start date: July 11, 2024
End date: October 17, 2025

a = 4.4031

b = -0.0004

s = 0.0586

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0004) – 1
= -13.91%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0586) – 1
= 26.39%

July 11, 2024 calculations

Top border of price channel:

Exp(Y936)
= Exp(a + b × X936 + 2 × s)
= Exp(a + b × 1,361 + 2 × s)
= Exp(4.4031 + -0.0004 × 1,361 + 2 × 0.0586)
= Exp(3.9619)
= $52.56

Bottom border of price channel:

Exp(Y936)
= Exp(a + b × X936 – 2 × s)
= Exp(a + b × 1,361 – 2 × s)
= Exp(4.4031 + -0.0004 × 1,361 – 2 × 0.0586)
= Exp(3.7277)
= $41.58

October 17, 2025 calculations

Top border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,824 + 2 × s)
= Exp(4.4031 + -0.0004 × 1,824 + 2 × 0.0586)
= Exp(3.7720)
= $43.47

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,824 – 2 × s)
= Exp(4.4031 + -0.0004 × 1,824 – 2 × 0.0586)
