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 DD 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: April 4, 2025
End date: October 9, 2025
a = 1.7930
b = 0.0014
s = 0.0354
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0014) – 1
= 68.30%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0354) – 1
= 15.22%

Top border of price channel:
Exp(Y1,121)
= Exp(a + b × X1,121 + 2 × s)
= Exp(a + b × 1,631 + 2 × s)
= Exp(1.7930 + 0.0014 × 1,631 + 2 × 0.0354)
= Exp(4.1902)
= $66.03
Bottom border of price channel:
Exp(Y1,121)
= Exp(a + b × X1,121 – 2 × s)
= Exp(a + b × 1,631 – 2 × s)
= Exp(1.7930 + 0.0014 × 1,631 – 2 × 0.0354)
= Exp(4.0485)
= $57.31

= Exp(4.4583)
= $86.34
Bottom border of price channel:
Exp(Y1,250)
= Exp(a + b × X1,250 – 2 × s)
= Exp(a + b × 1,819 – 2 × s)
