Based on my experience as an independent forex trader, evaluating the total trading costs on ADCB—especially for indices like the US100—raises several important considerations. First and foremost, I need to mention that, from what I have gathered, this broker operates under what appears to be suspicious regulatory circumstances. For me, this greatly impacts trust and transparency, two essential pillars for calculating real trading costs. While ADCB advertises access to a variety of products through their web platform and mobile app, their documentation on exact cost structures for indices is inconclusive. Generally, when I analyze trading costs, I look at factors such as spreads, commissions, overnight financing fees (sometimes called swaps), and any platform or account maintenance fees. However, I couldn't locate clear or published information from ADCB detailing their spreads or commissions for US100 trading. This lack of transparent, accessible cost information is a genuine red flag for me. Brokers that are regulated and reputable tend to provide a detailed breakdown of fees upfront, allowing traders to assess the true cost of executing trades—something that is critical when planning risk management and position sizing. Additionally, while the broker claims to offer various account types and some forms of bonuses, without clear terms and conditions, I’m cautious about assuming any fee advantages or reductions. In my view, when a brokerage lacks regulatory clarity and transparent fee structures, it’s difficult—if not impossible—to accurately calculate total trading costs, which could potentially expose traders to unexpected expenses or unfavorable trading conditions. Ultimately, for me, the ambiguity surrounding ADCB's cost structure and regulatory standing means that I would remain extremely conservative: I need full transparency on all trading-related costs, especially for leveraged products like indices, before considering any engagement.
