Version 1: Professional and Concise

An effective trendline must meet two core conditions:

1. Anchor the essential starting point: In an uptrend, connect higher lows (HL) precisely; in a downtrend, lock onto lower highs (LH), discarding invalid points within sideways movements.
2. Structure validation: Only when key structural confluences occur—such as new highs after a support zone retest or new lows triggered after resistance zone tests—does the trendline hold real practical value.

The essence of a trendline is not about “drawing it accurately,” but about penetrating market appearances to identify true turning points. Only by understanding trend structure can you draw the right trendline naturally—this is the core logic of technical analysis.

Version 2: Practical-Oriented

Want to draw trendlines that can accurately guide the market? Two conditions are indispensable:

1. The starting point must be “right”: For uptrends, look for continuously rising lows (HL); for downtrends, capture consistently falling highs (LH); avoid invalid points from random sideways movement.
2. The structure must be “real”: It must be verified in real trading, such as price making new highs after a support line is retested, or making new lows after a resistance line is tested—structural confluence is the key value.

Those “pseudo-trendlines” lacking structural significance only mislead decisions. The real key is to use trendlines to read trend structure and capture turning points—that’s the essence of technical analysis.

Version 3: Logically Thorough

The effectiveness of a trendline is determined by two core conditions:

1. Starting point anchors the essence of the trend: In an uptrend, anchor to higher lows (HL); in a downtrend, anchor to lower highs (LH). This is the foundation of trend continuation—not just connecting random points in consolidation.
2. Structural support grants practical value: It must be validated by key structures, such as new highs forming after a support zone retest or new lows triggered by a resistance zone test. Structural confluence provides its stability.

Clearly, the core of trendlines is not drawing precision, but the ability to penetrate market appearances and identify trend reversal points. Once you understand trend structure, drawing the right trendline comes naturally—this is the core logic of technical analysis. #外汇黄金 #黄金 #A成杰日记A[超话]#
