You draw the trend line and then if a stock breaks it you exit? Have you consistently beaten the S&P? Because missing out on stocks “breaking out” means you’re likely stuck with an inferior bag…Of course they work. How can something not work. They show the direction of the trend. What is it you expect a trend line to do?
FWIW I use trend lines to exit trades. When the trend breaks I exit. And no I rarely get out at the top and usually leave a little cash on the table.
