Building Synthetic USD and EUR Currency Indices in MetaTrader 5

Summary

The article explains how to calculate synthetic USD and EUR indices from weighted baskets of exchange rates. It gives the currency weights and geometric-mean formulas for both indices, including the base constants that calibrate them. It then outlines a MetaTrader 5 service that creates custom symbols, builds historical minute and tick data, and updates each index as constituent currency quotes arrive.

The implementation uses shared functions and symbol-weight structures so a basket can be configured with different symbols and weights. It also describes handling missing minute bars by using available prior data, calculating synthetic bar prices, and checking that calculated prices are finite, positive and internally consistent. The article is principally an implementation guide for constructing chartable synthetic instruments; it does not present a trading strategy or performance tests. Index behavior depends on the chosen basket, quote availability and calculation conventions, and the supplied USD and EUR baskets are specific examples rather than universal measures of currency value.

Key ideas

• The USD and EUR indices are calculated as weighted geometric means of exchange rates in currency baskets.
• The basket weights and base constants determine each index’s composition and scale.
• A MetaTrader 5 service can create custom symbols and update them using constituent quotes.
• The implementation accounts for missing minute bars and validates synthetic bar prices.
• The article explains index construction but does not evaluate a trading strategy or its returns.
