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 TILE 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: March 13, 2023
End date: November 20, 2024
a = -0.2267
b = 0.0018
s = 0.0885
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0018) – 1
= 92.94%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0885) – 1
= 42.47%

Top border of price channel:
Exp(Y830)
= Exp(a + b × X830 + 2 × s)
= Exp(a + b × 1,208 + 2 × s)
= Exp(-0.2267 + 0.0018 × 1,208 + 2 × 0.0885)
= Exp(2.1253)
= $8.38
Bottom border of price channel:
Exp(Y830)
= Exp(a + b × X830 – 2 × s)
= Exp(a + b × 1,208 – 2 × s)
= Exp(-0.2267 + 0.0018 × 1,208 – 2 × 0.0885)
= Exp(1.7713)
= $5.88

Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
