Based on my research and experience assessing brokers, I have to be especially cautious with Krungthai. From what I gathered, Krungthai is not a regulated brokerage and has a high-risk profile. One of the biggest red flags for me is the lack of transparency around fees and trading costs. Specifically regarding indices like the US100, Krungthai does not appear to offer index trading at all—according to the firm’s current offerings, only equities and derivatives are available, and there’s no mention of indices, forex, or commodities. As an independent trader, transparency around trading costs—spreads, commissions, overnight fees, and potential hidden charges—is absolutely essential for making informed decisions. With Krungthai, this information is either not disclosed or completely absent, which for me is unacceptable. On top of that, trading with an unregulated broker carries inherent risks, and the lack of a clear fee schedule raises my concerns about potential undisclosed costs or difficulties in accessing my funds. In summary, I could not determine or estimate total trading costs for indices such as the US100 through Krungthai, simply because these instruments are not listed among their products and the broker’s cost structure is unclear. For my own capital safety and clarity on costs, a regulated and fully transparent broker is always my preference.
