The currency strength indicator is a useful tool for technical analysis. It is a graphical representation of the strength or weakness of currencies in the forex market. The currency strength indicator compares the base currency with major currencies. It is one of the most powerful indicators used by professional traders to identify the strength of a currency compared to other currencies. When a currency is strong against other major currencies, the base currency indicates to buy, and the quote currency indicates to sell. Oppositely, a currency is weak against other major currencies; this base currency indicates to sell, and a quote currency indicates to buy. The currency strength indicator develops traders' sureness in making well-informed decisions while entering and exiting the market.
