Description:
These studies are based on the March 2007 article, Moving Average Crossovers (Part II), by Dimitris Tsokakis.
Formula Parameters:
Probable_SMACross.efs
- Fast MA Periods: 20
- Slow MA Periods: 30
SMA_StochCross.efs
- Fast MA Periods: 20
- Slow MA Periods: 30
- %K Length: 14
- %K Smoothing: 1
- %D Length: 3
Notes:
In real time, the Probable_SMACross.efs will print the messages as outlined in the side bar of the article to the formula output window. The SMA_StochCross.efs will draw a green/red circle on the chart to indicate the cross of the TC and green/red arrows for the MA crosses. The related article is copyrighted material.
