Unpopular opinion: You SHOULD redraw trendlines.

Two lows give you a line. Price breaks above and leaves it behind? Redraw through the new lows. Repeat.

A trendline is a hypothesis. You update it as the market gives you more evidence. The one touching the most points wins.

Kaufman backs this up — clinging to a line price already abandoned is pointless.

Adapt or get rekt.
