Good question. If you use higher leverage than recommended, your trades will take up more margin, and small market moves can wipe out your account faster. On the other hand, using lower leverage might make the EA miss trades or open smaller positions than it’s designed for. Basically, it could mess with how the system manages risk and executes orders. If the developer tested and optimized it for a certain leverage, it’s best to stick to that at least until you fully understand how it behaves under different settings.
