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 SIG 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 8, 2021
End date: November 20, 2024
a = 4.0006
b = 0.0003
s = 0.1600
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0003) – 1
= 10.40%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1600) – 1
= 89.65%

Top border of price channel:
Exp(Y323)
= Exp(a + b × X323 + 2 × s)
= Exp(a + b × 473 + 2 × s)
= Exp(4.0006 + 0.0003 × 473 + 2 × 0.1600)
= Exp(4.4489)
= $85.53
Bottom border of price channel:
Exp(Y323)
= Exp(a + b × X323 – 2 × s)
= Exp(a + b × 473 – 2 × s)
= Exp(4.0006 + 0.0003 × 473 – 2 × 0.1600)
= Exp(3.8089)
= $45.10

= Exp(4.0006 + 0.0003 × 1,826 + 2 × 0.1600)
= Exp(4.8157)
= $123.43
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(4.0006 + 0.0003 × 1,826 – 2 × 0.1600)
= Exp(4.1757)
= $65.09
