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 T 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: May 23, 2023
End date: September 30, 2025

a = 1.6031

b = 0.0011

s = 0.0530

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0011) – 1
= 48.45%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0530) – 1
= 23.63%

Top border of price channel:

Exp(Y545)
= Exp(a + b × X545 + 2 × s)
= Exp(a + b × 790 + 2 × s)
= Exp(1.6031 + 0.0011 × 790 + 2 × 0.0530)
= Exp(2.5642)
= $12.99

Bottom border of price channel:

Exp(Y545)
= Exp(a + b × X545 – 2 × s)
= Exp(a + b × 790 – 2 × s)
= Exp(1.6031 + 0.0011 × 790 – 2 × 0.0530)
= Exp(2.3521)
= $10.51

= Exp(3.4961)
= $32.99

Bottom border of price channel:

Exp(Y1,135)
= Exp(a + b × X1,135 – 2 × s)
= Exp(a + b × 1,651 – 2 × s)
