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 STRA 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: November 4, 2021
End date: July 25, 2024
a = 3.3505
b = 0.0007
s = 0.0979
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0007) – 1
= 30.63%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0979) – 1
= 47.94%

Top border of price channel:
Exp(Y575)
= Exp(a + b × X575 + 2 × s)
= Exp(a + b × 832 + 2 × s)
= Exp(3.3505 + 0.0007 × 832 + 2 × 0.0979)
= Exp(4.1554)
= $63.77
Bottom border of price channel:
Exp(Y575)
= Exp(a + b × X575 – 2 × s)
= Exp(a + b × 832 – 2 × s)
= Exp(3.3505 + 0.0007 × 832 – 2 × 0.0979)
= Exp(3.7637)
= $43.11

= Exp(4.8829)
= $132.02
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
