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 105.1; the same figure from the other source reads 97.15. Compared with LK.EXT.FX.SGD.BUY.D.

    Two agencies: 105.11 and 97.15, difference 7.96.

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

    LK.EXT.FX_DAILY_TT.SGD.BUY.D: value 105.1100 vs Data Library 97.1500. 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 source1 Oct 2018

    This series reads 129.5; the same figure from the other source reads 121.5. Compared with LK.EXT.FX.SGD.BUY.D.

    Two agencies: 129.539 and 121.47, difference 8.069.

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

    LK.EXT.FX_DAILY_TT.SGD.BUY.D: value 129.5391 vs Data Library 121.4700. USD/BUY 180.08 here vs ~167.0 the day before and after). A single bad row in the source file.

  • Error in the source3 Dec 2018

    This series reads 125.6; the same figure from the other source reads 128.6. Compared with LK.EXT.FX.SGD.BUY.D.

    Two agencies: 125.615 and 128.62, difference −3.005.

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

    LK.EXT.FX_DAILY_TT.SGD.BUY.D: value 125.6152 vs Data Library 128.6200. File reads 125.6152 where both its own neighbouring days (128.66-128.88) and the Library's value for the SAME date (128.62) sit at ~128.7 - the file's single-day figure is the outlier. Source data-entry error.

  • Error in the source6 Sep 2023

    This series reads 230.4; the same figure from the other source reads 563.8. Compared with LK.EXT.FX.SGD.BUY.D.

    Two agencies: 230.448 and 563.78, difference −333.332.

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

    LK.EXT.FX_DAILY_TT.SGD.BUY.D: value 230.4485 vs Data Library 563.7800. Here the FILE is right and the Library is wrong: the file reads 230.4485, matching its own neighbouring days (230.7-231.4) and the Library's own neighbouring days (230.5-230.8) almost exactly, while the Library's value for this one date is 563.78 - implausible for SGD/LKR at this time and inconsistent with the Library's own days either side. A Data Library data-quality issue on this date, not a fault in this loader's reading of the file.

  • Rounding19 Sep 2017

    This series reads 111.7; the same figure from the other source reads 111.7. Compared with LK.EXT.FX.SGD.BUY.D.

    Two agencies: 111.67 and 111.68, difference −0.01.

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

    LK.EXT.FX_DAILY_TT.SGD.BUY.D: value 111.6700 vs Data Library 111.6800. File 111.67 vs Library 111.68 - a one-cent rounding-level difference, not an error.

  • Rounding26 Apr 2018

    This series reads 116.6; the same figure from the other source reads 116.5. Compared with LK.EXT.FX.SGD.BUY.D.

    Two agencies: 116.59 and 116.49, difference 0.1.

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

    LK.EXT.FX_DAILY_TT.SGD.BUY.D: value 116.5895 vs Data Library 116.4900. 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.
