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 source5 Jul 2005

    Two figures from this source that should agree differ by 0.9 (99.68 against 98.78). Compared with LK.EXT.FX_DAILY_TT.USD.SELL.D.

    Consistency: 99.68 and 98.78, difference 0.9.

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

    LK.EXT.FX_DAILY_TT.USD.BUY.D: buying rate 99.6800 vs selling rate 98.7800 this day (buying should be < selling). SELL is the outlier: 98.78 vs its own neighbouring days 100.42-100.6 (BUY 99.68 is in line with its neighbours 99.55-99.67). Source data-entry error on the selling side.

  • Error in the source6 Oct 2015

    This series reads 144.5; the same figure from the other source reads 138.9. Compared with LK.EXT.FX.USD.BUY.D.

    Two agencies: 144.53 and 138.91, difference 5.62.

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

    LK.EXT.FX_DAILY_TT.USD.BUY.D: value 144.5300 vs Data Library 138.9100. 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 180.1; the same figure from the other source reads 167. Compared with LK.EXT.FX.USD.BUY.D.

    Two agencies: 180.083 and 167.03, difference 13.053.

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

    LK.EXT.FX_DAILY_TT.USD.BUY.D: value 180.0828 vs Data Library 167.0300. 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 155.5; the same figure from the other source reads 155.4. Compared with LK.EXT.FX.USD.BUY.D.

    Two agencies: 155.525 and 155.43, difference 0.095.

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

    LK.EXT.FX_DAILY_TT.USD.BUY.D: value 155.5247 vs Data Library 155.4300. 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.
