4 and 9 EMAs are thin lines, and all though they're good indicators, they tend to be emotional and react in shock. However, the 20 EMA, 20 McGinley and 100 EMA are patient and show you bigger moves. The pip gains are insane when the 20 EMA crosses the 20 McGinley. The 100 EMA adds a major level of structure for trend or counter trend continuation. This is a patient moving scheme that has opportunity for amazing results.
Just my thoughts.
