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 BIO 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: June 24, 2021
End date: July 15, 2024
a = 7.1674
b = -0.0009
s = 0.0977
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0009) – 1
= -28.65%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0977) – 1
= 47.83%

Top border of price channel:
Exp(Y399)
= Exp(a + b × X399 + 2 × s)
= Exp(a + b × 581 + 2 × s)
= Exp(7.1674 + -0.0009 × 581 + 2 × 0.0977)
= Exp(6.8255)
= $921.07
Bottom border of price channel:
Exp(Y399)
= Exp(a + b × X399 – 2 × s)
= Exp(a + b × 581 – 2 × s)
= Exp(7.1674 + -0.0009 × 581 – 2 × 0.0977)
= Exp(6.4347)
= $623.06

Top border of price channel:
Exp(Y1,166)
= Exp(a + b × X1,166 + 2 × s)
= Exp(a + b × 1,698 + 2 × s)
= Exp(7.1674 + -0.0009 × 1,698 + 2 × 0.0977)
= Exp(5.7926)
= $327.85
Bottom border of price channel:
Exp(Y1,166)
= Exp(a + b × X1,166 – 2 × s)
= Exp(a + b × 1,698 – 2 × s)
= Exp(7.1674 + -0.0009 × 1,698 – 2 × 0.0977)
= Exp(5.4017)
