The amount of capital in forex trading actually influences trading performance. Indeed, with small capital, the risk of loss is also small because starting with a low number, the worst case is losing all your capital when a stop-out occurs. If the trader is reckless, the larger capital hence the risk is even higher if they work without a good trading plan.
However, in practice, using small capital logically has fewer opportunities, so if you experience several consecutive losses you may be subject to a margin call. Meanwhile, with larger capital, there are more opportunities if you manage risk well, which increases the chances of higher profits.
