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 5, 2020
End date: January 17, 2023
a = 4.8500
b = -0.0005
s = 0.0699
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0005) – 1
= -15.76%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0699) – 1
= 32.26%

Top border of price channel:
Exp(Y377)
= Exp(a + b × X377 + 2 × s)
= Exp(a + b × 545 + 2 × s)
= Exp(4.8500 + -0.0005 × 545 + 2 × 0.0699)
= Exp(4.7337)
= $113.71
Bottom border of price channel:
Exp(Y377)
= Exp(a + b × X377 – 2 × s)
= Exp(a + b × 545 – 2 × s)
= Exp(4.8500 + -0.0005 × 545 – 2 × 0.0699)
= Exp(4.4540)
= $85.97

Top border of price channel:
Exp(Y928)
= Exp(a + b × X928 + 2 × s)
= Exp(a + b × 1,348 + 2 × s)
= Exp(4.8500 + -0.0005 × 1,348 + 2 × 0.0699)
= Exp(4.3563)
= $77.96
Bottom border of price channel:
Exp(Y928)
= Exp(a + b × X928 – 2 × s)
= Exp(a + b × 1,348 – 2 × s)
= Exp(4.8500 + -0.0005 × 1,348 – 2 × 0.0699)
= Exp(4.0766)
= $58.95
