Constructing a EUR Currency Index from Weighted Exchange Rates

Article MQL5 code base

Summary

The document explains an EUR index indicator built as a weighted geometric combination of EURUSD, EURGBP, EURJPY, EURSEK, and EURCHF. Its fixed coefficients define each pair’s contribution to the index. Two settings control which price is used in the calculation and whether the plotted index is vertically reversed. The indicator can be displayed on charts for any instrument.

All five currency pairs must be available from the data server for the calculation to be correct. The indicator may also take time to load the required price history on first use or after a timeframe change. The document supplies the formula and describes the display options, but gives no rationale for the weights, index rebasing method, validation against a benchmark, or trading performance. It is therefore a technical description of a currency index indicator, not a tested trading strategy.

Key ideas

  • The EUR index combines five euro exchange rates using fixed exponents and a multiplier.
  • The applied-price setting determines which price series feeds the calculation.
  • A reverse setting flips the chart vertically without changing the underlying currency pairs.
  • The calculation depends on data availability and history for every included pair.
  • The document gives no evidence that the index generates profitable trading signals.
