The ratio of risk to return is one of the fundamental concepts in the world of investment and trading, as it helps investors determine the relationship between potential risks and expected returns. Simply put, this term refers to the amount of risk that an investor must bear against the returns they can achieve. For example, if a trade has a ratio of 1:3, it means that if you are willing to risk losing 1 dollar, you can expect to gain 3 dollars.

By carefully calculating the risk-to-return ratio, traders can make more informed decisions, which helps improve trading strategies and reduce losses. The goal should always be to achieve a low risk-to-high return ratio.
