You can get started with any amount! However, one thing you’ll want to keep in mind is that the smaller your starting capital, the more commissions and fees will negatively impact your account balance. The most important rule of trading is to ONLY trade with money you can afford to lose.
Before funding your trading account with any amount, ask yourself “if I lost 100% of this money, would I be okay with that?”. If – and only if – the answer is yes, should you consider moving forward with your deposit.
