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 DDD 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 14, 2021
End date: November 19, 2024
a = 4.3837
b = -0.0019
s = 0.2088
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0019) – 1
= -49.41%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.2088) – 1
= 130.53%

Top border of price channel:
Exp(Y289)
= Exp(a + b × X289 + 2 × s)
= Exp(a + b × 421 + 2 × s)
= Exp(4.3837 + -0.0019 × 421 + 2 × 0.2088)
= Exp(4.0153)
= $55.44
Bottom border of price channel:
Exp(Y289)
= Exp(a + b × X289 – 2 × s)
= Exp(a + b × 421 – 2 × s)
= Exp(4.3837 + -0.0019 × 421 – 2 × 0.2088)
= Exp(3.1801)
= $24.05

Top border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(4.3837 + -0.0019 × 1,826 + 2 × 0.2088)
= Exp(1.3922)
= $4.02
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(4.3837 + -0.0019 × 1,826 – 2 × 0.2088)
= Exp(0.5570)
= $1.75
