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: July 1, 2021
End date: May 10, 2024
a = 7.3656
b = -0.0009
s = 0.0994
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0009) – 1
= -29.07%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0994) – 1
= 48.83%

Top border of price channel:
Exp(Y539)
= Exp(a + b × X539 + 2 × s)
= Exp(a + b × 780 + 2 × s)
= Exp(7.3656 + -0.0009 × 780 + 2 × 0.0994)
= Exp(6.8305)
= $925.63
Bottom border of price channel:
Exp(Y539)
= Exp(a + b × X539 – 2 × s)
= Exp(a + b × 780 – 2 × s)
= Exp(7.3656 + -0.0009 × 780 – 2 × 0.0994)
= Exp(6.4329)
= $621.95

Top border of price channel:
Exp(Y1,258)
= Exp(a + b × X1,258 + 2 × s)
= Exp(a + b × 1,824 + 2 × s)
= Exp(7.3656 + -0.0009 × 1,824 + 2 × 0.0994)
= Exp(5.8481)
= $346.57
Bottom border of price channel:
Exp(Y1,258)
= Exp(a + b × X1,258 – 2 × s)
= Exp(a + b × 1,824 – 2 × s)
= Exp(7.3656 + -0.0009 × 1,824 – 2 × 0.0994)
= Exp(5.4505)
= $232.87
