Trendline Breakout: Price breaks above a downward trendline (or below an upward trendline), signaling a potential trend reversal or continuation. Retest: After the breakout, price returns to test the broken trendline, which now acts as support (or resistance). Move Up: If the retest holds and buyers step in, price resumes upward momentum, confirming the breakout and often providing a low-risk entry.
