We can argue about correct trendlines and which guru teaches them the best all day. That's why hardly anyone on here has real trading success. Unless someone has come up with a systematic way of testing them, it's all just anecdotal experiences and cherry-picked results.The correct way to draw a trendline .... is from right (most current data) to left (history). Almost no one does it that way. And although many swings can line up on a line only two points are needed.
Which I learned from Tom DeMark.
BTW missing an "e" in Trader Vic's last name Sperandeo.
