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 FLGT 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 27, 2021
End date: May 14, 2024

a = 5.5633

b = -0.0014

s = 0.1518

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0014) – 1
= -39.88%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1518) – 1
= 83.50%

Top border of price channel:

Exp(Y429)
= Exp(a + b × X429 + 2 × s)
= Exp(a + b × 623 + 2 × s)
= Exp(5.5633 + -0.0014 × 623 + 2 × 0.1518)
= Exp(4.9984)
= $148.18

Bottom border of price channel:

Exp(Y429)
= Exp(a + b × X429 – 2 × s)
= Exp(a + b × 623 – 2 × s)
= Exp(5.5633 + -0.0014 × 623 – 2 × 0.1518)
= Exp(4.3914)
= $80.75

Exp(Y1,258)
= Exp(a + b × X1,258 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(5.5633 + -0.0014 × 1,826 + 2 × 0.1518)
= Exp(3.3217)
= $27.71

Bottom border of price channel:

Exp(Y1,258)
= Exp(a + b × X1,258 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(5.5633 + -0.0014 × 1,826 – 2 × 0.1518)
= Exp(2.7146)
= $15.10
