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 TFX 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 30, 2020
End date: March 20, 2023
a = 6.6049
b = -0.0009
s = 0.0938
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0009) – 1
= -27.41%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0938) – 1
= 45.55%

Top border of price channel:
Exp(Y394)
= Exp(a + b × X394 + 2 × s)
= Exp(a + b × 571 + 2 × s)
= Exp(6.6049 + -0.0009 × 571 + 2 × 0.0938)
= Exp(6.2916)
= $539.99
Bottom border of price channel:
Exp(Y394)
= Exp(a + b × X394 – 2 × s)
= Exp(a + b × 571 – 2 × s)
= Exp(6.6049 + -0.0009 × 571 – 2 × 0.0938)
= Exp(5.9162)
= $370.99

Top border of price channel:
Exp(Y972)
= Exp(a + b × X972 + 2 × s)
= Exp(a + b × 1,411 + 2 × s)
= Exp(6.6049 + -0.0009 × 1,411 + 2 × 0.0938)
= Exp(5.5545)
= $258.39
Bottom border of price channel:
Exp(Y972)
= Exp(a + b × X972 – 2 × s)
= Exp(a + b × 1,411 – 2 × s)
= Exp(6.6049 + -0.0009 × 1,411 – 2 × 0.0938)
= Exp(5.1791)
= $177.52
