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 189.8; the same figure from the other source reads 218. Compared with LK.EXT.FX.GBP.SELL.D.

    Two agencies: 189.75 and 217.97, difference −28.22.

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

    LK.EXT.FX_DAILY_TT.GBP.SELL.D: value 189.7500 vs Data Library 217.9700. 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 227; the same figure from the other source reads 224. Compared with LK.EXT.FX.GBP.SELL.D.

    Two agencies: 226.993 and 223.96, difference 3.033.

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

    LK.EXT.FX_DAILY_TT.GBP.SELL.D: value 226.9933 vs Data Library 223.9600. USD/BUY 180.08 here vs ~167.0 the day before and after). A single bad row in the source file.

  • Error in the source25 Feb 2021

    This series reads 278.4; the same figure from the other source reads 272.4. Compared with LK.EXT.FX.GBP.SELL.D.

    Two agencies: 278.416 and 272.42, difference 5.996.

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

    LK.EXT.FX_DAILY_TT.GBP.SELL.D: value 278.4161 vs Data Library 272.4200. Here again the FILE is right and the Library is wrong: file reads 278.4161, consistent with its own neighbouring days (276-278.4) and the Library's own neighbouring days (272.4-278.4 - trending up); the Library's own value for this date (272.42) is a dip inconsistent with the days either side of it in the Library itself. A Data Library data-quality issue on this date.

  • Rounding26 Apr 2018

    This series reads 222.8; the same figure from the other source reads 222.9. Compared with LK.EXT.FX.GBP.SELL.D.

    Two agencies: 222.776 and 222.95, difference −0.174.

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

    LK.EXT.FX_DAILY_TT.GBP.SELL.D: value 222.7762 vs Data Library 222.9500. 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.
