I am an engineer with over 30 years of system development experience. Centered on Dow Theory and SMC, I design and develop chart analysis tools to enhance the reproducibility of discretionary judgment. At GogoJungle, we provide DowWave Marker (DWM) to visualize market structure, KiriLevelX (KLX) to visualize price ranges, and Momentum Equalizer (MEQ) to visualize momentum. Rather than flashy appearance or easy trading signals, we prioritize organizing market structure, price ranges, and momentum to objectify traders' own decision criteria. We continually improve by empirically validating usability, visibility, and stable operation on actual charts.
