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 PEN 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: June 18, 2024
End date: January 27, 2025
a = 1.9481
b = 0.0020
s = 0.0513
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0020) – 1
= 106.30%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0513) – 1
= 22.75%

Top border of price channel:
Exp(Y1,105)
= Exp(a + b × X1,105 + 2 × s)
= Exp(a + b × 1,603 + 2 × s)
= Exp(1.9481 + 0.0020 × 1,603 + 2 × 0.0513)
= Exp(5.2309)
= $186.95
Bottom border of price channel:
Exp(Y1,105)
= Exp(a + b × X1,105 – 2 × s)
= Exp(a + b × 1,603 – 2 × s)
= Exp(1.9481 + 0.0020 × 1,603 – 2 × 0.0513)
= Exp(5.0259)
= $152.30
