Based on my direct experience investigating Grand Capital as a platform option, I discovered that they do not support the popular MT4 or MT5 trading platforms, nor do they offer cTrader. Instead, Grand Capital provides its own suite of trading platforms, including desktop, mobile, and web-based versions. While they advertise that these allow for account balance checks and portfolio management, I found the lack of MT4 and MT5 integration particularly limiting. As an experienced trader, I've come to rely on the flexibility, stability, and extensive toolsets offered by mainstream platforms like MT4, MT5, and cTrader. Their absence at Grand Capital introduces a significant adjustment period and forces users to adapt to a less familiar and possibly less robust trading environment. What's more concerning for me is the impression that Grand Capital's proprietary platforms might lack industry-standard features, integrations, and third-party support that experienced traders have come to expect. In my view, the decision not to offer MT4, MT5, or cTrader could hinder both execution efficiency and analytical capabilities for those of us accustomed to such professional-grade tools. Furthermore, switching to new and unproven platforms always carries additional risks, especially given Grand Capital's overall issues with transparency and regulatory status. For me, this absence of proven trading platforms is a serious disadvantage that calls for considerable caution.
