The difference between trendlines on daily lows vs closing

Here you can see that drawing trendlines on a daily low plotted into the future can make a 5 to 10% difference in only a matter of months on your predictions. Always use the daily/weekly close price, because where the market closes is important. We have a nice rebound today but unfortunately, it is dying out into the close. Don't be fooled by the algo's, short-term rebounds have been cashed in for the day, but who is holding overnight? Not many.
