This indicator shows the relative strength of 8 major currencies: USD, EUR, GBP, AUD, NZD, CAD, CHF and JPY.
The strength value is normalized to the range 0-100:
- The value above 60 means strong.
- The value below 40 means weak.
The basic principle
Given eight currencies, USD,EUR,GBP,AUD,NZD,CAD,CHF,JPY, where each pair of two can be combined, resulting in a total of 28 pairs, a reverse algorithm is used to extract the strength of the eight currencies from these 28 pairs
EURUSD,GBPUSD,AUDUSD,NZDUSD, USDCAD,USDCHF,USDJPY,EURGBP, EURAUD,EURNZD,EURCAD,EURCHF, EURJPY,GBPAUD,GBPNZD,GBPCAD, GBPCHF,GBPJPY,AUDNZD,AUDCAD, AUDCHF,AUDJPY,NZDCAD,NZDCHF, NZDJPY,CADCHF,CADJPY,CHFJPY
Basic Usage
- if the strength value above 60 means it is strong, below 40 means it is weak.
- buy the strongest currency and sell the weakeast currency.
- if all currencies are in the range of 40-60 which means the market is flat.
- if you are long term trade. it is better to trade the pair after its two currencies just crossed.
- if a currency crosses from below 60 to above 60,it means it is becoming strong.
- if a currency crosses from above 40 to below 40,it means it is becoming weak.
- if a currency crosses from below 20 to above 20, it is better to stop selling it
- if a currency crossed from above 80 to below 80, it is better to stop buying it.

This indicator needs the data of all 28 pairs, I offer an EA to download data : https://www.mql5.com/en/blogs/post/728216

believe that compared to most trend indicators, the “Currency Relative Strength” provides a clearer directional signal for currency pair movements and is more forward-looking
