Source discrepancies

What the warehouse found when it checked this series: the same figure from two agencies, splice overlaps, published rates against ones recalculated from the index, and outliers.

  • Error in the source6 Oct 2015

    This series reads 183.4; the same figure from the other source reads 209.7. Compared with LK.EXT.FX.GBP.BUY.D.

    Two agencies: 183.37 and 209.67, difference −26.3.

    LK.EXT.FX_DAILY_TT.GBP.BUY.D: IF_Buying_Selling file vs the Data Library

    LK.EXT.FX_DAILY_TT.GBP.BUY.D: value 183.3700 vs Data Library 209.6700. Whole-day anomaly in the source file: every daily-TT currency (buy and sell) jumps on this one day while every neighbouring day matches the Data Library exactly (e.g. USD/BUY 144.53 here vs 138.9x the day before and after, in both the file and the Library) - re-verified series by series. A single bad row in IF_Buying_Selling_Exchange_Rates...xlsx, not a parsing issue.

    This series reads 220.1; the same figure from the other source reads 216.7. Compared with LK.EXT.FX.GBP.BUY.D.

    LK.EXT.FX_DAILY_TT.GBP.BUY.D: IF_Buying_Selling file vs the Data Library

    LK.EXT.FX_DAILY_TT.GBP.BUY.D: value 215.8705 vs Data Library 215.7000. Every currency differs from the Data Library by under 0.2 LKR on this date - the file records 4 decimal places (e.g. USD/BUY 155.5247) where the Library's copy has 2 (155.43); a precision/rounding difference between two CBSL publications of the same TT rate, not an error.
