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 DAR 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: September 22, 2025
End date: January 16, 2026

a = 0.0109

b = 0.0020

s = 0.0332

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0020) – 1
= 107.21%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0332) – 1
= 14.21%

Top border of price channel:

Exp(Y1,174)
= Exp(a + b × X1,174 + 2 × s)
= Exp(a + b × 1,707 + 2 × s)
= Exp(0.0109 + 0.0020 × 1,707 + 2 × 0.0332)
= Exp(3.4846)
= $32.61

Bottom border of price channel:

Exp(Y1,174)
= Exp(a + b × X1,174 – 2 × s)
= Exp(a + b × 1,707 – 2 × s)
= Exp(0.0109 + 0.0020 × 1,707 – 2 × 0.0332)
= Exp(3.3517)
= $28.55
