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: January 15, 2025
End date: January 23, 2026
a = 5.3474
b = -0.0006
s = 0.0300
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0006) – 1
= -21.10%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0300) – 1
= 12.74%

Top border of price channel:
Exp(Y999)
= Exp(a + b × X999 + 2 × s)
= Exp(a + b × 1,451 + 2 × s)
= Exp(5.3474 + -0.0006 × 1,451 + 2 × 0.0300)
= Exp(4.4650)
= $86.92
Bottom border of price channel:
Exp(Y999)
= Exp(a + b × X999 – 2 × s)
= Exp(a + b × 1,451 – 2 × s)
= Exp(5.3474 + -0.0006 × 1,451 – 2 × 0.0300)
= Exp(4.3451)
= $77.10

= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,824 + 2 × s)
= Exp(5.3474 + -0.0006 × 1,824 + 2 × 0.0300)
= Exp(4.2228)
= $68.22
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,824 – 2 × s)
= Exp(5.3474 + -0.0006 × 1,824 – 2 × 0.0300)
= Exp(4.1029)
= $60.52
