discrepancy between trend lines drawn on same chart on other sites?
there seems to be discrepancy between trend lines drawn on exact same type chart/points using other charting sites ,
how can this be?
in other words, a long extended trend line drawn on stockcharts.com does not reach the same price/time a year or two later as the exact same line from identical two points drawn on other charting sites, why?
I experimented with simple linear, daily line chart trend line using identical 2 points to draw and extend trendline
