4 Currencies V2_NSC is a Relative Currency Strength indicator designed for Forex markets, focusing on the AUD, USD, EUR, and JPY. It measures and displays the relative strength of these four major currencies by analyzing their performance against each other across pairs such as AUDUSD, AUDEUR, AUDJPY, EURUSD, EURJPY, and USDJPY. Users can define the lookback period (default 14 bars) to adjust responsiveness and apply an optional smoothing period (default 5 bars) using an exponential moving average to reduce noise.

The indicator plots each currency’s strength as a separate line in a dedicated window below the main chart, avoiding clutter on price action charts. Calculations are based on the close of each bar, ensuring that the displayed lines do not repaint or change after bar completion. This tool aids in better currency pair selection, understanding whether moves in pairs are driven by strength or weakness of individual currencies, and tailoring analysis to individual trading styles.

Due to its comprehensive data processing across multiple pairs, it may be resource-intensive on some systems. Adjusting period settings or refreshing the chart can resolve occasional performance issues.
