Just draw some straight lines on chart and you will win money. Does that make any sense? Can you prove it works or it is a tale?
I say no, especially in the modern algo-dominated markets. The burden of proof is on the trend-line believers, though. They need to either

I say no, especially in the modern algo-dominated markets. The burden of proof is on the trend-line believers, though. They need to either
1) Develop and code an objective trendline system that beats the market (using standard industry metrics) in both back and forward-testing or
2) Track the trades of a more subjective trendline-based trader using a 3rd-party auditing service and see how they perform.
I doubt anyone can really code an objective trendline system with programming. Give the same chart to 10 "pro charters", very likely all of them would draw different trendlines on the same chart.
Does trendline work?
To a skilled technical trader - trend lines have value as a tool. Of course trend lines work, they plot the desired linear or curved line - it's like asking if a ruler works. Many traders neglect the curved trend lines.
