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 source20 Aug 2007

    Two figures from this source that should agree differ by 7.7 (84.12 against 91.82). Compared with LK.EXT.FX_DAILY_TT.CHF.BUY.D.

    Consistency: 91.82 and 84.12, difference 7.7.

    CHF: TT buying rate should be less than the selling rate

    LK.EXT.FX_DAILY_TT.CHF.BUY.D: buying rate 91.8200 vs selling rate 84.1200 this day (buying should be < selling). SELL is the outlier: 84.12 vs its own neighbouring days 92.86-93.22/93.96-94.09 (BUY 91.82 is in line with its neighbours). Source data-entry error on the selling side.

  • Error in the source14 Aug 2008

    This series reads 161.6; the same figure from the other source reads 99.98. Compared with LK.EXT.FX.CHF.SELL.D.

    Two agencies: 161.58 and 99.98, difference 61.6.

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

    LK.EXT.FX_DAILY_TT.CHF.SELL.D: value 161.5800 vs Data Library 99.9800. File reads 161.58; both the day before (100.38) and after (99.06) in the file, and the Data Library's own value for this date (99.98), sit around 100 - the file's single-day figure is the outlier. Source data-entry error.

  • Error in the source6 Oct 2015

    This series reads 153.3; the same figure from the other source reads 147.8. Compared with LK.EXT.FX.CHF.SELL.D.

    Two agencies: 153.26 and 147.76, difference 5.5.

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

    LK.EXT.FX_DAILY_TT.CHF.SELL.D: value 153.2600 vs Data Library 147.7600. 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.

  • Error in the source13 Jun 2017

    This series reads 160.1; the same figure from the other source reads 160.7. Compared with LK.EXT.FX.CHF.SELL.D.

    Two agencies: 160.05 and 160.65, difference −0.6.

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

    LK.EXT.FX_DAILY_TT.CHF.SELL.D: value 160.0500 vs Data Library 160.6500. File reads 160.05 where its own neighbouring days (160.73-160.83) and the Library's value for the same date (160.65) sit at ~160.7-160.8 - a modest (0.6) but consistent single-day dip in the file only. Source data-entry error.

  • Error in the source1 Oct 2018

    This series reads 185.3; the same figure from the other source reads 175.6. Compared with LK.EXT.FX.CHF.SELL.D.

    Two agencies: 185.297 and 175.6, difference 9.697.

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

    LK.EXT.FX_DAILY_TT.CHF.SELL.D: value 185.2965 vs Data Library 175.6000. 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 163.1; the same figure from the other source reads 163.1. Compared with LK.EXT.FX.CHF.SELL.D.

    Two agencies: 163.114 and 163.13, difference −0.016.

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

    LK.EXT.FX_DAILY_TT.CHF.SELL.D: value 163.1143 vs Data Library 163.1300. 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.
