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 APPF 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

Start date: February 17, 2022
End date: July 29, 2024
a = 3.9720
b = 0.0012
s = 0.1063
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0012) – 1
= 54.49%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1063) – 1
= 52.97%

Top border of price channel:
Exp(Y288)
= Exp(a + b × X288 + 2 × s)
= Exp(a + b × 416 + 2 × s)
= Exp(3.9720 + 0.0012 × 416 + 2 × 0.1063)
= Exp(4.6802)
= $107.80
Bottom border of price channel:
Exp(Y288)
= Exp(a + b × X288 – 2 × s)
= Exp(a + b × 416 – 2 × s)
= Exp(3.9720 + 0.0012 × 416 – 2 × 0.1063)
= Exp(4.2552)
= $70.47

Top border of price channel:
Exp(Y900)
= Exp(a + b × X900 + 2 × s)
= Exp(a + b × 1,309 + 2 × s)
= Exp(3.9720 + 0.0012 × 1,309 + 2 × 0.1063)
= Exp(5.7444)
= $312.43
Bottom border of price channel:
Exp(Y900)
= Exp(a + b × X900 – 2 × s)
= Exp(a + b × 1,309 – 2 × s)
= Exp(3.9720 + 0.0012 × 1,309 – 2 × 0.1063)
= Exp(5.3193)
