About the author

Hi, I'm Jakub. I've been building Pine Script systems for over 7 years on TradingView — from simple indicators to multi-layer confluence systems. MarketSonar is the distillate of that work: one tool that shows exactly what I look at before any decision.

MarketSonar is the tool's brand; I've long published as Spokojne Rynki ("Calm Markets") — and the name is the manifesto. I don't believe in "sure things", premium Telegram signals or screaming green candles in thumbnails. I believe in craft: levels, trend context, risk management, and the calm that comes from understanding what you see on the chart.

The indicator set in the dashboard — ATR trailing stops, specific moving averages, Camarilla levels, trendlines — and the timeframes they run on are the fruit of years of trial, error and verification against my own decisions. I paid tuition for this knowledge: entries into the middle of strong zones, ignoring the higher-timeframe context, trusting a single indicator. MarketSonar and the course exist so you don't have to repeat those mistakes on your own account.

House rules

• Education, not advice. I won't tell you what to buy. I teach you to read the market and give you an instrument that makes it easier.
• Honesty over marketing. The tool's limitations (e.g. repaint on a forming HTF bar) are described openly, before you pay.
• No profit guarantees. Anyone promising them is lying to you.
