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: May 3, 2024
End date: April 1, 2025
a = 9.2844
b = -0.0031
s = 0.0906
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0031) – 1
= -67.23%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0906) – 1
= 43.66%

Top border of price channel:
Exp(Y1,028)
= Exp(a + b × X1,028 + 2 × s)
= Exp(a + b × 1,492 + 2 × s)
= Exp(9.2844 + -0.0031 × 1,492 + 2 × 0.0906)
= Exp(4.9056)
= $135.04
Bottom border of price channel:
Exp(Y1,028)
= Exp(a + b × X1,028 – 2 × s)
= Exp(a + b × 1,492 – 2 × s)
= Exp(9.2844 + -0.0031 × 1,492 – 2 × 0.0906)
= Exp(4.5433)
= $94.00
