US Dollar Index Basket Weights and Synthetic Index Construction

Summary

The document explains the U.S. Dollar Index as a weighted geometric measure of the dollar against six major currencies. It lists the basket weights and gives a formula that combines the exchange rates, with negative exponents for EURUSD and GBPUSD and positive exponents for the other quoted pairs. The base coefficient is described as historical.

It also outlines a MetaTrader service that calculates a synthetic dollar-index symbol from live currency quotes, then updates its bars and ticks so the index can be charted, used with indicators, or included in strategy tests. This supports analysis of dollar strength, but the document provides no validation of the synthetic series, trading rules, or performance evidence. The service description is technical and does not establish that its fast update loop improves market analysis or execution.

Key ideas

• The dollar index represents the dollar against a basket of six currencies using a weighted geometric calculation.
• The listed weights determine each exchange rate’s influence, with quote direction reflected in the exponent signs.
• A MetaTrader service can calculate and update a synthetic dollar-index symbol from current basket quotes.
• The document explains construction and intended chart use but gives no strategy results or validation evidence.
