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 TDW 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: July 12, 2024
End date: November 22, 2024
a = 13.2776
b = -0.0051
s = 0.0463
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0051) – 1
= -84.46%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0463) – 1
= 20.33%

Top border of price channel:
Exp(Y1,163)
= Exp(a + b × X1,163 + 2 × s)
= Exp(a + b × 1,691 + 2 × s)
= Exp(13.2776 + -0.0051 × 1,691 + 2 × 0.0463)
= Exp(4.7459)
= $115.11
Bottom border of price channel:
Exp(Y1,163)
= Exp(a + b × X1,163 – 2 × s)
= Exp(a + b × 1,691 – 2 × s)
= Exp(13.2776 + -0.0051 × 1,691 – 2 × 0.0463)
= Exp(4.5609)
= $95.66

= Exp(4.0676)
= $58.42
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,824 – 2 × s)
