Trend lines aren't some magic bullet that solves everything.

But here's what they actually do: they keep you from entering at stupid prices.

Most beginners mess this up. They draw lines at random angles, force connects to the chart, or end up with spaghetti everywhere.

The right way? Pick your swing highs and lows, connect them cleanly, and let price action tell you when the line matters. That's it.

If you want to stop leaving money on the table and actually read your charts, start getting this basic stuff right.
