Hello, I'm Woney. I specialize in one thing only: developing TradingView indicators. I believe that what's more important than "looking pretty" is having clear rules that don't waver in real trading, stable operation, and handling exceptional situations. [Indicators I Create] - Condition-based signals/alerts (alarms) - Entry/exit assistance, trend/volatility/volume-based filters - Guards to prevent over-entry/risk management (can be made optional) - Chart readability improvements (labels/lines/status windows/tables, etc.) [Development Process] 1) You provide your desired conditions "in words" → I structure them into indicator rules. 2) To avoid confusion on the chart → I organize the display methods (labels/lines/tables) together. 3) I proactively check for potential issues in real trading (duplicate signals, exceptional periods, etc.) and implement them stably. [Recommended For] - Those who have desired conditions but find implementation difficult - Those who need filters/refinement because they have too many or too few signals - Those who need readable indicators that users can understand immediately
