Let's be honest: many people fill their charts with lines of various colors crossing and intersecting, feeling like trading experts. But then they get harshly educated by the market.

The reality is so brutal—those support and resistance lines, trend lines you've drawn, are nine times out of ten useless; they're just psychological comfort blankets.

But that doesn't mean drawing lines is useless per se. The key is that many people use them incorrectly. Meaningful technical lines serve to help you anchor a clear reference framework: where is support, where is resistance, where are the points of trend suppression and breakout? They give you a "monitoring point" so you can observe closely—when the price approaches this area, how is the battle between bulls and bears? Is the volume keeping up? Is it a decisive breakout or repeated testing?

Conversely, those ineffective lines are purely figments of the imagination. Forcibly connecting unrelated points into a line and then self-affirming "this must be the bottom, that must be the top." This isn't analysis; it's divination—one of the fastest ways to lose money.

What's even more brutal is that even if you predict the position and judge the direction correctly, the psychological torment during execution and the market backlash during holding positions can wipe out most traders' capital. Technical analysis might improve your win rate, but it doesn't solve a more fundamental problem: how to survive longer in the market, stay steady, and continue to profit?

This is also why I shifted from repeatedly studying line analysis to seeking more fundamental, more certain methods. The key isn't about making lines more fancy, but about finding a set of methodologies and tools that genuinely help traders reduce risk, improve decision quality, and sustain profitability.
