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 POST 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 2, 2024
End date: October 20, 2025
a = 4.9841
b = -0.0002
s = 0.0292
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0002) – 1
= -6.01%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0292) – 1
= 12.38%

Top border of price channel:
Exp(Y950)
= Exp(a + b × X950 + 2 × s)
= Exp(a + b × 1,381 + 2 × s)
= Exp(4.9841 + -0.0002 × 1,381 + 2 × 0.0292)
= Exp(4.8080)
= $122.49
Bottom border of price channel:
Exp(Y950)
= Exp(a + b × X950 – 2 × s)
= Exp(a + b × 1,381 – 2 × s)
= Exp(4.9841 + -0.0002 × 1,381 – 2 × 0.0292)
= Exp(4.6913)
= $109.00
