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 TDS 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 16, 2024
End date: November 20, 2024
a = -1.3002
b = 0.0026
s = 0.0753
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0026) – 1
= 153.65%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0753) – 1
= 35.13%

Top border of price channel:
Exp(Y1,065)
= Exp(a + b × X1,065 + 2 × s)
= Exp(a + b × 1,548 + 2 × s)
= Exp(-1.3002 + 0.0026 × 1,548 + 2 × 0.0753)
= Exp(2.7979)
= $16.41
Bottom border of price channel:
Exp(Y1,065)
= Exp(a + b × X1,065 – 2 × s)
= Exp(a + b × 1,548 – 2 × s)
= Exp(-1.3002 + 0.0026 × 1,548 – 2 × 0.0753)
= Exp(2.4969)
= $12.14

= Exp(3.5069)
= $33.34
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
