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: November 8, 2022
End date: November 4, 2025
a = 0.9377
b = 0.0016
s = 0.2010
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0016) – 1
= 78.62%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.2010) – 1
= 123.43%

Top border of price channel:
Exp(Y505)
= Exp(a + b × X505 + 2 × s)
= Exp(a + b × 733 + 2 × s)
= Exp(0.9377 + 0.0016 × 733 + 2 × 0.2010)
= Exp(2.5047)
= $12.24
Bottom border of price channel:
Exp(Y505)
= Exp(a + b × X505 – 2 × s)
= Exp(a + b × 733 – 2 × s)
= Exp(0.9377 + 0.0016 × 733 – 2 × 0.2010)
= Exp(1.7007)
= $5.48

Top border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(0.9377 + 0.0016 × 1,825 + 2 × 0.2010)
= Exp(4.2402)
= $69.42
Bottom border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(0.9377 + 0.0016 × 1,825 – 2 × 0.2010)
= Exp(3.4363)
= $31.07
