If you passed the suitability questionnaires during onboarding, two margin accounts would have been opened for you: a ZAR margin account for local trading and a USD margin account for offshore trading. To trade with leverage, simply select one of these accounts when placing your trades.
When you place a trade on the order screen, you will see the margin rate, which can range from 15% to 40%, and the required margin to place the trade.
It's important to understand the risks of trading with leverage and to manage your positions carefully.
