Satorino - I use the EMA 11 High and EMA 11 Low for my upper and lower trend lines.
When the price remains below the upper trend line and does not touch the upper trend line during the entire month, that is the beginning of Phase I.
When the price touches or goes above the upper trend line, that is the beginning of Phase II.
Hope this helps. I have to go to a ball game tonight. Tomorrow I will post a chart of each of the cycles I listed so you can see what I am talking about.
