Mark Minervini's #3 Trend Template requirement is for the 200 day moving average line to be trending up for at least 1 month but preferably 4 to 5 months at a minimum.
A stock with 200 day moving average trending up for 1+ month is potentially making an "early turn" into stage 2 uptrend. Most often, stocks with 200 day moving average trending up for 4+ months is indicative of a stock in a stage 2 uptrend.
This simple indicator colors the moving average line BLUE for stocks with 200 MA trending up for 1+ month and CYAN for ones with 200 MA trending up for 4+ months. The indicator provides fast and simple way to visualize the long term trend and help trend following traders stay on the right side of the trade.
Indicator is customizable from colors to line thickness.
