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 102.4; the same figure from the other source reads 114. Compared with LK.EXT.FX_DAILY_TT.AUD.SELL.D.

    Two agencies: 113.97 and 102.39, difference 11.58.

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

    LK.EXT.FX_DAILY_TT.AUD.SELL.D: value 113.9700 vs Data Library 102.3900. 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 124.6; the same figure from the other source reads 125.2. Compared with LK.EXT.FX_DAILY_TT.AUD.SELL.D.

    Two agencies: 125.168 and 124.64, difference 0.528.

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

    LK.EXT.FX_DAILY_TT.AUD.SELL.D: value 125.1679 vs Data Library 124.6400. USD/BUY 180.08 here vs ~167.0 the day before and after). A single bad row in the source file.

  • Rounding14 Mar 2017

    This series reads 117.3; the same figure from the other source reads 117.3. Compared with LK.EXT.FX_DAILY_TT.AUD.SELL.D.

    Two agencies: 117.28 and 117.29, difference −0.01.

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

    LK.EXT.FX_DAILY_TT.AUD.SELL.D: value 117.2800 vs Data Library 117.2900. File 117.28 vs Library 117.29 - a one-cent rounding-level difference, not an error.

  • Rounding26 Apr 2018

    This series reads 121.7; the same figure from the other source reads 121.6. Compared with LK.EXT.FX_DAILY_TT.AUD.SELL.D.

    Two agencies: 121.583 and 121.67, difference −0.087.

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

    LK.EXT.FX_DAILY_TT.AUD.SELL.D: value 121.5826 vs Data Library 121.6700. 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.
