About me
I am a software developer and active trader who believes that a trading tool is only as good as the logic and engineering behind it.
My approach to Pine Script is shaped by my professional IT background and my own experience in the markets. I understand the frustration of repainting or laggy signals, which is why I prioritize solid programming and high-performance scripts. My goal is to ensure your tools behave exactly the same in live market conditions as they do in backtesting.
I build everything from the ground up with clean visuals, structured logic, and real-world usability in mind.

I knew when I saw Ralf's other reviews, he would be the right person to work with and knew he would be well qualified for the job. Like others have said, his turn around time Is quick. He messaged straight away as soon as I sent my order through, and he was there every step of the way to make sure that...
