In the stock markets, trading is speculation on financial instruments with the aim of making a profit. Trading is mainly based on technical analysis, fundamental analysis and the application of a specific strategy to trade. People who practice the trading profession are known as traders (or, alternatively, traders or negotiators on their own account) who can work independently, in an investment fund, in a bank or in another financial institution.2 Traders are classified into scalpers, day traders, swing traders, and position traders depending on the duration of their trades. The opposite of a trader is an investor, who is naturally long-term. A trader can act as a broker, speculator, arbitrageur or hedge trader, with the aim of making a profit. They can also be private traders and manage their own capital, manage capital from third parties such as money managers.
