Usage scenarios
Trade the pair of the strongest and weakest currencies
One powerful way to use this tool is to trade the currency pair made up of the strongest and weakest currencies. When the base currency is stronger, the pair is more likely to be in an uptrend; when the quote currency is stronger, it may signal a downtrend. For example, if AUD is the strongest and JPY is the weakest, you could consider buying AUDJPY.
Determine entry points with other indicators
It is also useful for confirming entry signals generated by other indicators. Check whether the Historical Strength Graph supports the same direction before finalizing your entry. For example, even if the RSI suggests that USDCHF is oversold, you may choose to skip the trade if CHF is stronger than USD.
Look for reversals after major strength changes
Based on large movements in currency strengths, you can watch for potential reversals. If a currency’s strength value changes suddenly, a reversal may follow. In that case, consider looking for buy or sell opportunities in the related instruments.
Sync with chart for backtesting
The Historical Strength Graph calculates and displays currency strengths based on the selected chart period. You can review your past trades by checking the currency strength levels at specific points in time.

The message is displayed as an object on the chart and can be deleted in the same way as other standard objects.
How to set up
After applying the indicator to the chart, set the parameters according to your style.
Step 1
First, open the "Inputs" tab.
Step 2
Set the parameters as follows.
① Specified currency only
Select ON if you want to display only the line charts of the currencies defined in the "Specified currency" parameter.
② Specified currency
When "Specified currency only" is set to ON, it calculates strengths only for the currencies listed in this field. You can enter multiple currencies by separating them with commas. An error will occur if an unsupported currency or only a single currency is entered.
③ Link to main chart display
Select ON to automatically adjust the range of strength data to align with the display of the main chart.
④ Calculation period
Enter the number of hours for calculating past strength data. For example, entering "10" will calculate strengths over the past 10 hours. An error will occur if the value is smaller than the duration of one bar or excessively large.
⑤ Display period
Set the number of bars of past strength data to display. For example, entering "12" on a 15-minute timeframe will show data from the past 3 hours. If the value exceeds the "Max bars in chart" setting in MT4/MT5, an error will be returned.
⑥ Live data location
Choose where to display the current strength data: right, top, or bottom.
The Historical Strength Graph calculates currency strengths for the period defined in the “Calculation period” parameter. Large values (e.g., ~10,000) may slow the downloading of historical data, causing delayed chart loading.
Very large values (e.g., ~100,000) may cause a timeout error. The tool will still work if you download the missing data or re-apply the indicator until the download completes. Please note that complete data for all symbols used in the currency strength calculation is required.
Because MT4 has lower processing power than MT5, delays or errors may occur even with smaller "Calculation period" values.
