About Anna and David Coulling – Creators of Quantum Trading
Anna and David Coulling are the husband-and-wife team behind Quantum Trading. With over three decades of combined trading experience across global markets, they have built a reputation for practical, no-nonsense education and innovative tools. Anna, the driving force behind the brand, is a renowned author, educator, and trader. She has dedicated her career to demystifying financial markets through her pioneering work in volume price analysis (VPA). David provides essential technical expertise to support the development of the Quantum indicator suite. Together, they empower traders worldwide with reliable, volume-based insights.
Anna's trading journey began in the futures and commodities markets, where she quickly recognised the limitations of price-only analysis. This led to the creation of Volume Price Analysis—a methodology that combines price action with volume to reveal professional intent. VPA shows what smart money is doing: high volume on moves confirms conviction, while low volume at extremes signals weakness or traps. Volume is the heartbeat of the market—it represents real money and participation. Price can deceive, but volume exposes the truth. Anna's approach cuts through noise, helping traders align with institutional flows for disciplined decisions.
Anna’s Best Selling Book
Anna's best-selling book, A Complete Guide to Volume Price Analysis, is widely regarded as the bible of volume trading. First published in 2012, it remains the definitive starting point for new volume traders. The book explains VPA clearly with real examples across forex, stocks, futures, and commodities. It teaches reading accumulation (buying at lows) and distribution (selling at highs). Beginners love its logical progression—no jargon, just actionable insights. Experienced traders return to it for refinement.
This foundational work inspired the Quantum Trading indicator suite—tools designed to visualise VPA signals across platforms such as MT4, MT5, NinjaTrader, and TradingView.
Quantum Trading reflects Anna and David's passion for education and innovation. Their indicators—such as the volume point of control (VPOC), the volume relative strength indicator (VRSI), the VWAP (volume-weighted average price), and many more—bring VPA to life with precision.
Whether you're a beginner learning volume concepts or an advanced trader refining strategies, Quantum tools provide the edge to trade with confidence. Join thousands of traders who rely on Anna and David's expertise for consistent results.
