FOREX_Currency_Power
This EA is a real-time currency power index visualization tool for the five major FOREX currencies (EUR, USD, GBP, CHF, JPY). It calculates and displays relative currency strength using a weighted basket of currency pairs, rendering results as a CGraphic line chart on the chart. It does not open any trades; it serves purely as an analytical dashboard for currency momentum assessment.

Strategy analysis
This EA is not a trading strategy but a currency strength analysis utility. Its core concept measures relative currency strength by constructing a weighted basket of 4 related currency pairs for each currency, where direct pairs receive +1.0 weight and inverse pairs receive -1.0 weight. Entry and exit conditions are not applicable as this tool does not open positions. Position sizing and money management are similarly not applicable. The tool uses a circular buffer to store the most recent 400 data points, calculating each currency's current price average via the CCurrencyPowerIndex class as the strength value. For visualization, it uses CGraphic to render 6 curves (a 50-baseline plus 5 currency lines) with the Y-axis fixed at 0-100 range, refreshing data every 100 milliseconds via a millisecond timer.
Strengths
- Real-time visualization of five major currency strengths, intuitively displaying relative momentum differences to assist trading decisions
- Uses circular buffer for historical data management, ensuring memory efficiency and avoiding frequent array reallocations
- Weighted basket approach is sound, with direct pair +1 and inverse pair -1 logic conforming to currency pair pricing principles
Weaknesses
- Does not execute any trading operations, serving only as an analysis tool, limiting value for users expecting automated trading
- Hardcodes 5 currencies and 20 currency pair weights, lacking flexibility and configurability, with no ability to extend to other currencies
- Lacks data validity checks and error handling, with incomplete fault tolerance when custom symbol creation fails or data sources are unavailable
Possible improvements
- Externalize currency list and weight configuration as input parameters, allowing users to customize currency baskets and weight allocations
- Add exception handling and reconnection mechanisms, enabling automatic retry or graceful degradation when custom symbol data is unavailable
Risk assessment
Overall risk: Safe
- This EA does not execute any trading operations, posing no financial risk
- High-frequency timer (100ms) may cause excessive resource usage on low-performance environments
