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 TER 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: January 6, 2025
End date: March 31, 2025
a = 15.4644
b = -0.0060
s = 0.0542
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0060) – 1
= -88.96%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0542) – 1
= 24.19%

Top border of price channel:
Exp(Y1,198)
= Exp(a + b × X1,198 + 2 × s)
= Exp(a + b × 1,741 + 2 × s)
= Exp(15.4644 + -0.0060 × 1,741 + 2 × 0.0542)
= Exp(5.0633)
= $158.11
Bottom border of price channel:
Exp(Y1,198)
= Exp(a + b × X1,198 – 2 × s)
= Exp(a + b × 1,741 – 2 × s)
= Exp(15.4644 + -0.0060 × 1,741 – 2 × 0.0542)
= Exp(4.8466)
= $127.31

Top border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(15.4644 + -0.0060 × 1,825 + 2 × 0.0542)
= Exp(4.5562)
= $95.22
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(15.4644 + -0.0060 × 1,825 – 2 × 0.0542)
= Exp(4.3396)
= $76.67
