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 CDW 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: February 8, 2024
End date: April 29, 2025
a = 6.9259
b = -0.0010
s = 0.0595
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0010) – 1
= -30.60%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0595) – 1
= 26.86%

Top border of price channel:
Exp(Y950)
= Exp(a + b × X950 + 2 × s)
= Exp(a + b × 1,379 + 2 × s)
= Exp(6.9259 + -0.0010 × 1,379 + 2 × 0.0595)
= Exp(5.6650)
= $288.59
Bottom border of price channel:
Exp(Y950)
= Exp(a + b × X950 – 2 × s)
= Exp(a + b × 1,379 – 2 × s)
= Exp(6.9259 + -0.0010 × 1,379 – 2 × 0.0595)
= Exp(5.4271)
= $227.48

= Exp(5.2187)
= $184.70
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(6.9259 + -0.0010 × 1,825 – 2 × 0.0595)
= Exp(4.9808)
= $145.59
