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 TDY 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: April 10, 2024
End date: October 22, 2025
a = 5.1026
b = 0.0007
s = 0.0408
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0007) – 1
= 28.72%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0408) – 1
= 17.72%

Top border of price channel:
Exp(Y848)
= Exp(a + b × X848 + 2 × s)
= Exp(a + b × 1,234 + 2 × s)
= Exp(5.1026 + 0.0007 × 1,234 + 2 × 0.0408)
= Exp(6.0377)
= $418.91
Bottom border of price channel:
Exp(Y848)
= Exp(a + b × X848 – 2 × s)
= Exp(a + b × 1,234 – 2 × s)
= Exp(5.1026 + 0.0007 × 1,234 – 2 × 0.0408)
= Exp(5.8745)
= $355.84

= Exp(a + b × X1,233 + 2 × s)
= Exp(a + b × 1,794 + 2 × s)
= Exp(5.1026 + 0.0007 × 1,794 + 2 × 0.0408)
= Exp(6.4250)
= $617.05
Bottom border of price channel:
Exp(Y1,233)
= Exp(a + b × X1,233 – 2 × s)
= Exp(a + b × 1,794 – 2 × s)
