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 source14 Nov 2017

    This series reads 23.68; the same figure from the other source reads 22.68. Compared with LK.EXT.FX_DAILY_TT.CNY.SELL.D.

    Two agencies: 22.68 and 23.68, difference −1.

    LK.EXT.FX_DAILY_TT.CNY.SELL.D: IF_Buying_Selling file vs the Data Library

    LK.EXT.FX_DAILY_TT.CNY.SELL.D: value 22.6800 vs Data Library 23.6800. File reads 22.68 where both its own neighbouring days (23.66-23.71) and the Library's value for the same date (23.68) sit at ~23.7 - the diff is almost exactly 1.00, consistent with a single mistyped digit (23.68 -> 22.68). Source data-entry error.

  • Error in the source1 Oct 2018

    This series reads 25.2; the same figure from the other source reads 26.05. Compared with LK.EXT.FX_DAILY_TT.CNY.SELL.D.

    Two agencies: 26.054 and 25.2, difference 0.854.

    LK.EXT.FX_DAILY_TT.CNY.SELL.D: IF_Buying_Selling file vs the Data Library

    LK.EXT.FX_DAILY_TT.CNY.SELL.D: value 26.0541 vs Data Library 25.2000. USD/BUY 180.08 here vs ~167.0 the day before and after). A single bad row in the source file.

  • Rounding26 Apr 2018

    This series reads 25.5; the same figure from the other source reads 25.46. Compared with LK.EXT.FX_DAILY_TT.CNY.SELL.D.

    Two agencies: 25.458 and 25.5, difference −0.042.

    LK.EXT.FX_DAILY_TT.CNY.SELL.D: IF_Buying_Selling file vs the Data Library

    LK.EXT.FX_DAILY_TT.CNY.SELL.D: value 25.4579 vs Data Library 25.5000. 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.
