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 7, 2024
End date: November 13, 2024
a = 6.4419
b = -0.0006
s = 0.0405
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0006) – 1
= -19.84%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0405) – 1
= 17.57%

Top border of price channel:
Exp(Y1,058)
= Exp(a + b × X1,058 + 2 × s)
= Exp(a + b × 1,539 + 2 × s)
= Exp(6.4419 + -0.0006 × 1,539 + 2 × 0.0405)
= Exp(5.5906)
= $267.89
Bottom border of price channel:
Exp(Y1,058)
= Exp(a + b × X1,058 – 2 × s)
= Exp(a + b × 1,539 – 2 × s)
= Exp(6.4419 + -0.0006 × 1,539 – 2 × 0.0405)
= Exp(5.4287)
= $227.85

Top border of price channel:
Exp(Y1,252)
= Exp(a + b × X1,252 + 2 × s)
= Exp(a + b × 1,819 + 2 × s)
= Exp(6.4419 + -0.0006 × 1,819 + 2 × 0.0405)
= Exp(5.4210)
= $226.10
Bottom border of price channel:
Exp(Y1,252)
= Exp(a + b × X1,252 – 2 × s)
= Exp(a + b × 1,819 – 2 × s)
= Exp(6.4419 + -0.0006 × 1,819 – 2 × 0.0405)
= Exp(5.2591)
= $192.30
