D_Three Ten Osc

[eSignal]

File Name: d3_10osc.efs

Description:
D_Three Ten Osc

Formula Parameters:
EMA Length 1 : 5
EMA Length 2 : 12
EMA Length 3 : 18


Notes:
This indicator allows the user to plot a daily 3-10 Oscillator
on a Tick Bar Chart or any intraday interval.
Walter Bressert's 3-10 Oscillator is a detrending oscillator derived
from subtracting a 10 day moving average from a 3 day moving average.
The second plot is an 16 day simple moving average of the 3-10 Oscillator.
The 16 period moving average is the slow line and the 3/10 oscillator is
the fast line.
For more information on the 3-10 Oscillator see Walter Bressert's book
"The Power of Oscillator/Cycle Combinations"
