In recent years, trading robots (algorithmic trading systems) have become increasingly prevalent tools across various markets, including forex pairs like USD and EUR, as well as equities such as Apple Inc. (AAPL) $AAPL and major indices like the S&P 500 (SPX) $^GSPC. Automation enables faster execution and reduces emotional bias in trading decisions. However, a critical question arises: how safe and effective is it to entrust your investments to a trading robot?

Financial markets today are witnessing a surge in the use of algorithmic trading systems to automate trades. Currency pairs such as USD/EUR $USDEUR, stocks like Apple Inc. $AAPL (AAPL), and the S&P 500 Index (SPX) $^SPX rank among the most liquid and widely traded assets, where trading robots play a key role in enhancing trade speed and accuracy. Amid volatile markets and high information flow, these automated systems assist traders and institutional investors in minimizing human errors and swiftly reacting to market shifts.
