As a trader with a conservative approach to cost management, I always scrutinize the fee structure of any broker before entrusting them with my funds. With GMO CLICK, I found their overall trading costs for indices such as the US100 to be quite transparent, but it’s important to note the specifics before making any commitment. The standout feature, in my experience, is that GMO CLICK typically advertises zero commissions on many trading products—including most indices via CFDs. This means that, unlike brokers who charge a fixed commission per trade, the main trading costs for index trades here come from the bid-ask spread. While exact spread values for the US100 aren’t specified on their WikiFX profile, the platform emphasizes tight spreads as a competitive advantage. From my perspective, this can be cost-effective for active traders, but it also means spreads may vary with market conditions—potentially leading to higher-than-expected costs during volatile periods. What is clear is that non-trading fees are minimal: there are no deposit, account management, or inactivity fees, and withdrawal fees only apply if withdrawing in foreign currency (which wouldn’t usually concern a yen-based account for Japanese indices, but is a possible factor for other currencies). I strongly advise prospective clients to monitor live spread quotations on the GMO CLICK platform before executing any trades to accurately assess total transaction costs under real conditions. This lets me avoid surprises and helps maintain a disciplined cost structure in my trading.
