With gently rising stocks we can usually draw a trendline under the price troughs and exit when price breaks below that line for 2 consecutive weeks. However, when price is rising very strongly without the usual down weeks to create higher troughs you can use for a stop loss and price is miles above your trendl ine - meaning it might have to fall 20% or more before it breaks below that trendline. We don't really want to sit watching that fall only to give away 20%+ of our hard-earned profits. This video shows how the daily chart can help solve this problem.
