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 XRAY 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: January 6, 2021
End date: January 10, 2023
a = 4.9657
b = -0.0012
s = 0.1157
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0012) – 1
= -34.93%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1157) – 1
= 58.86%

Top border of price channel:
Exp(Y412)
= Exp(a + b × X412 + 2 × s)
= Exp(a + b × 597 + 2 × s)
= Exp(4.9657 + -0.0012 × 597 + 2 × 0.1157)
= Exp(4.4944)
= $89.51
Bottom border of price channel:
Exp(Y412)
= Exp(a + b × X412 – 2 × s)
= Exp(a + b × 597 – 2 × s)
= Exp(4.9657 + -0.0012 × 597 – 2 × 0.1157)
= Exp(4.0315)
= $56.35

Top border of price channel:
Exp(Y918)
= Exp(a + b × X918 + 2 × s)
= Exp(a + b × 1,331 + 2 × s)
= Exp(4.9657 + -0.0012 × 1,331 + 2 × 0.1157)
= Exp(3.6303)
= $37.72
Bottom border of price channel:
Exp(Y918)
= Exp(a + b × X918 – 2 × s)
= Exp(a + b × 1,331 – 2 × s)
= Exp(4.9657 + -0.0012 × 1,331 – 2 × 0.1157)
= Exp(3.1674)
= $23.75
