- // This code written per specifications found at

- // Version 1.0
- //
- // This code calculates the Alpha, Delta, Beta and Gamma values
- // but they are not used in the filter criteria as specified
- // by the article which this code was based on.
- //
- // Look for additional changes as I tweak the below code.
- // I will also include Scan feature and Backtesting in future release.
