Based on my experience as a trader and after reviewing Yuanta’s structure, the total cost of trading indices such as the US100 with Yuanta involves several components that need close attention. Yuanta’s commission for stock transactions is 0.25% of the transaction amount, with a minimum charge of HK$100 per trade. However, since indices are generally accessed via futures or derivatives, the exact fee for US100 index trading could be slightly different—often realized through derivatives commission or contract-specific fees. Additional transaction costs include standard Hong Kong market levies: stamp duty at 0.10%, transaction levy at 0.0027%, and a trading fee at 0.00565%, though these may apply directly to equities rather than index contracts. For futures and options products, margin interest (Prime + 5%) and contract specifications will play a role in cost, so clarity on the contract type is essential. One positive for me is Yuanta does not impose direct fees on deposits or withdrawals, but third-party or banking costs could arise, especially for international remittance or certain transfer types. Lastly, the absence of a demo account makes it difficult to fully preview these costs in a risk-free environment before trading live. Given the steps involved, it’s prudent I always calculate expected charges based on my planned trade size and frequency, and carefully review the specific terms for the chosen index contract on Yuanta’s platform. This conservative approach has helped me manage risk and avoid unwanted surprises in my trading costs.
