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 ATI 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: August 14, 2025
End date: December 30, 2025
a = -1.6063
b = 0.0035
s = 0.0394
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0035) – 1
= 255.30%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0394) – 1
= 17.08%

Top border of price channel:
Exp(Y1,159)
= Exp(a + b × X1,159 + 2 × s)
= Exp(a + b × 1,687 + 2 × s)
= Exp(-1.6063 + 0.0035 × 1,687 + 2 × 0.0394)
= Exp(4.3323)
= $76.12
Bottom border of price channel:
Exp(Y1,159)
= Exp(a + b × X1,159 – 2 × s)
= Exp(a + b × 1,687 – 2 × s)
= Exp(-1.6063 + 0.0035 × 1,687 – 2 × 0.0394)
= Exp(4.1745)
= $65.01
