A trading strategy refers to a set of rules or guidelines that an investor follows when making decisions about buying and selling financial instruments such as stocks, options, or futures contracts. The goal is usually to maximize profits while minimizing losses by carefully analyzing market data and using various analytical tools. A well-designed trading strategy takes into account the investor's risk tolerance level, investment objectives, and time horizon. It may involve technical analysis, fundamental analysis or a combination of both to identify potential entry and exit points for trades. Ultimately, the success of any trading strategy depends on its ability to generate consistent returns while minimizing risks over the long term.
