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 218; the same figure from the other source reads 189.8. Compared with LK.EXT.FX_DAILY_TT.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 224; the same figure from the other source reads 227. Compared with LK.EXT.FX_DAILY_TT.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 272.4; the same figure from the other source reads 278.4. Compared with LK.EXT.FX_DAILY_TT.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 222.9; the same figure from the other source reads 222.8. Compared with LK.EXT.FX_DAILY_TT.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.

    CBSL's exchange rate lookup pages against the Data Library

    CBSL's exchange rate lookup and the Data Library disagree on 13-18 days per currency between 2010 and April 2018, by a few cents to a few rupees (USD sell 2011-02-28: 91.67 in the lookup, 111.67 in the library).
