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: July 26, 2024
a = 0.3404
b = 0.0015
s = 0.2421
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0015) – 1
= 72.23%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.2421) – 1
= 163.36%

Top border of price channel:
Exp(Y828)
= Exp(a + b × X828 + 2 × s)
= Exp(a + b × 1,198 + 2 × s)
= Exp(0.3404 + 0.0015 × 1,198 + 2 × 0.2421)
= Exp(2.6091)
= $13.59
Bottom border of price channel:
Exp(Y828)
= Exp(a + b × X828 – 2 × s)
= Exp(a + b × 1,198 – 2 × s)
= Exp(0.3404 + 0.0015 × 1,198 – 2 × 0.2421)
= Exp(1.6407)
= $5.16

= Exp(0.3404 + 0.0015 × 1,824 + 2 × 0.2421)
= Exp(3.5416)
= $34.52
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,824 – 2 × s)
= Exp(0.3404 + 0.0015 × 1,824 – 2 × 0.2421)
= Exp(2.5732)
