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 DLB 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: November 3, 2023
End date: November 19, 2024
a = 5.1589
b = -0.0005
s = 0.0331
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0005) – 1
= -16.17%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0331) – 1
= 14.15%

Top border of price channel:
Exp(Y995)
= Exp(a + b × X995 + 2 × s)
= Exp(a + b × 1,444 + 2 × s)
= Exp(5.1589 + -0.0005 × 1,444 + 2 × 0.0331)
= Exp(4.5273)
= $92.50
Bottom border of price channel:
Exp(Y995)
= Exp(a + b × X995 – 2 × s)
= Exp(a + b × 1,444 – 2 × s)
= Exp(5.1589 + -0.0005 × 1,444 – 2 × 0.0331)
= Exp(4.3949)
= $81.04

= Exp(4.3426)
= $76.91
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
