No, the vertical lines are timeframe. The starting day for timeframe is new each year, and sometime in October (for stocks it is usually Oct 7 if the 7th is during the work week). From there, you have 4 quarters of 64 "trading" days. The 64 day interval is different in forex, because we have trading activity on sunday.

This is much different from static MML. (MML don't change at all.)
