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: May 8, 2024
a = 0.2500
b = 0.0015
s = 0.2580
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0015) – 1
= 71.03%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.2580) – 1
= 180.67%

Top border of price channel:
Exp(Y883)
= Exp(a + b × X883 + 2 × s)
= Exp(a + b × 1,279 + 2 × s)
= Exp(0.2500 + 0.0015 × 1,279 + 2 × 0.2580)
= Exp(2.6465)
= $14.10
Bottom border of price channel:
Exp(Y883)
= Exp(a + b × X883 – 2 × s)
= Exp(a + b × 1,279 – 2 × s)
= Exp(0.2500 + 0.0015 × 1,279 – 2 × 0.2580)
= Exp(1.6145)
= $5.03

= Exp(0.2500 + 0.0015 × 1,826 + 2 × 0.2580)
= Exp(3.4508)
= $31.53
Bottom border of price channel:
Exp(Y1,258)
= Exp(a + b × X1,258 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(0.2500 + 0.0015 × 1,826 – 2 × 0.2580)
= Exp(2.4188)
= $11.23
