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 TDC 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 30, 2023
End date: March 31, 2025
a = 5.2601
b = -0.0011
s = 0.0910
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0011) – 1
= -33.41%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0910) – 1
= 43.92%
May 30, 2023 calculations
Top border of price channel:
Exp(Y795)
= Exp(a + b × X795 + 2 × s)
= Exp(a + b × 1,154 + 2 × s)
= Exp(5.2601 + -0.0011 × 1,154 + 2 × 0.0910)
= Exp(4.1566)
= $63.86
Bottom border of price channel:
Exp(Y795)
= Exp(a + b × X795 – 2 × s)
= Exp(a + b × 1,154 – 2 × s)
= Exp(5.2601 + -0.0011 × 1,154 – 2 × 0.0910)
= Exp(3.7925)
= $44.37

Top border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(5.2601 + -0.0011 × 1,825 + 2 × 0.0910)
= Exp(3.4092)
= $30.24
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(5.2601 + -0.0011 × 1,825 – 2 × 0.0910)
= Exp(3.0451)
= $21.01
