Building Multi-Currency Indicators from Synchronized Forex Pair Data

Summary

This article describes an MQL5 indicator that derives relative currency index series from seven USD currency pairs, then applies RSI, MACD, or a Stochastic Oscillator to those indexes. Its architecture separates plotted output lines from quote data, currency indexes, and intermediate Stochastic calculations using indicator buffers. Users can select which currencies to display, line colors, indicator type, and calculation periods.

A central implementation concern is synchronizing the source pairs’ bars so their close values refer to comparable times, particularly at the current bar. The article outlines buffer assignment, initialization, and calculations, and shows examples of the three indicator types. The history length is capped in the example to limit memory use, while the author notes that the calculation approach is not optimized. The article focuses on data handling and buffer design rather than trading rules or performance; it explicitly leaves the merits and drawbacks of currency-cluster strategies undiscussed.

Key ideas

• The indicator derives eight currency indexes from synchronized closes of seven USD pairs.
• RSI, MACD, or Stochastic can be calculated over each index series.
• Separate buffers hold plotted lines, source prices, indexes, and intermediate Stochastic values.
• Synchronization across instruments is needed to align data by bar time.
• The example limits history for memory reasons and does not evaluate strategy performance.
