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 ADI 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: December 30, 2020
End date: January 31, 2023
a = 5.0997
b = 0.0000
s = 0.0652
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0000) – 1
= -0.58%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0652) – 1
= 29.80%

Top border of price channel:
Exp(Y408)
= Exp(a + b × X408 + 2 × s)
= Exp(a + b × 590 + 2 × s)
= Exp(5.0997 + 0.0000 × 590 + 2 × 0.0652)
= Exp(5.2207)
= $185.07
Bottom border of price channel:
Exp(Y408)
= Exp(a + b × X408 – 2 × s)
= Exp(a + b × 590 – 2 × s)
= Exp(5.0997 + 0.0000 × 590 – 2 × 0.0652)
= Exp(4.9599)
= $142.58

Top border of price channel:
Exp(Y932)
= Exp(a + b × X932 + 2 × s)
= Exp(a + b × 1,352 + 2 × s)
= Exp(5.0997 + 0.0000 × 1,352 + 2 × 0.0652)
= Exp(5.2086)
= $182.85
Bottom border of price channel:
Exp(Y932)
= Exp(a + b × X932 – 2 × s)
= Exp(a + b × 1,352 – 2 × s)
= Exp(5.0997 + 0.0000 × 1,352 – 2 × 0.0652)
= Exp(4.9478)
= $140.87

a = 4.7222
b = 0.0003
s = 0.0637
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0003) – 1
= 11.94%
Price channel spread:
Exp(4 × s) – 1

Top border of price channel:
Exp(Y674)
= Exp(a + b × X674 + 2 × s)
= Exp(a + b × 976 + 2 × s)
= Exp(4.7222 + 0.0003 × 976 + 2 × 0.0637)
= Exp(5.1511)
= $172.61
Bottom border of price channel:
Exp(Y674)
= Exp(a + b × X674 – 2 × s)
= Exp(a + b × 976 – 2 × s)
= Exp(4.7222 + 0.0003 × 976 – 2 × 0.0637)
= Exp(4.8964)
= $133.81

Top border of price channel:
Exp(Y1,258)
= Exp(a + b × X1,258 + 2 × s)
= Exp(a + b × 1,824 + 2 × s)
= Exp(4.7222 + 0.0003 × 1,824 + 2 × 0.0637)
= Exp(5.4131)
= $224.32
Bottom border of price channel:
Exp(Y1,258)
