MQL5 ADVANCED: Code a Currency Strength Filter for EAs

Initialize a currency strength filter expert advisor, and execute on_tick only when a new bar forms, using the previous candle close for currency strength calculations.

Create an RC input group and build a ROC value function to calculate relative strength, using close prices, periods, and timeframes to generate currency strength signals.

Define eight currencies and store symbol strings for euro, usd, gbp, aud, nzd, jpy, chf, and cut, then compile them into a currency array to assess relative strength.

Learn to compute currency ROC values for major currencies by building tuple-based functions, averaging seven pair values, and normalizing results to reveal currency strength for expert advisors.

Store ROC values for euro, USD, pound, JPY, CHF, aussie, and NZD into two arrays and copy them for safe reordering across two time frames.

Rank currencies by strength from strongest to weakest using currency position arrays for the first and second time frames. Sort and map the results to identify each currency’s rank.

Create a symbol from the strongest and weakest currencies to capture the fastest market moves, using symbol present to verify existence and building first and second symbol versions.

Print and comment symbols in mql5, identify the strongest currencies on hourly and daily charts, and build a dashboard to visualize the strongest and weakest currencies.

Set up global x and y offsets, panel size and base, and currency labels to build a two-timeframe dashboard with daily and hourly panels, then implement drawing functions.

Build a dashboard base for a currency strength filter by implementing a draw panel function that creates a panel base and header, and sets position, size, colors, font, and text.

Create a build block function to render currency panels, setting name, x distance, y distance, and text, and style with navy text on khaki and a flat border.

Build panel elements inside the draw panel function to display ranked currencies across multiple time frames, using currency variables, typecasting, and normalization to show the strongest values.

Test the currency strength dashboard in MT5, validate ROC calculations for base and quote currencies, and observe how yen and CAD strength affect the meter across time frames.

Debug a currency strength filter by tracing code line by line, fixing bugs in ROC calculations across euro, USD, pound, yen, and other currencies, and validating the dashboard panel.

Code a momentum-based sure-fire strategy with a currency-strength filter to select moving currency pairs, and update the dashboard to replace a second time frame with the rock indicator and MACD.

Apply a currency strength filter within your trading strategy to identify markets moving toward your target, and complete the two assignments to tailor it to your needs.
