Trading costs related to buying and selling shares on the JSE can vary significantly between platforms.

1. The size of your portfolio. Whilst most plaforms charge the same commission irrespective of size, there are some (e.g. Rand Swiss) which will provide you considerably lower brokerage commission once your portfolio value gets to a certain size.
2. The size of your trade. All brokers take the size of your trade into account when determining your trading fees. However, some apply a sliding scale. Others a tiered scale. Most charge a minimum fee.
