Avoiding unreliable or untested automated systems is crucial because many trading bots and Expert Advisors (EAs) promise high returns but lack proven performance or risk management. Some automated systems are based on flawed strategies, over-optimized for past data, or even scams designed to drain trading accounts. Before using any system, thoroughly backtest it on historical data, run it in a demo account, and ensure it aligns with sound trading principles. Relying on unverified bots can lead to unexpected losses, so it’s essential to understand how they work and monitor their performance rather than assuming they will generate consistent profits.
