As someone with years of experience trading forex and indices, I approach every new broker with a careful, methodical eye—especially when considering total trading costs, which are critical to long-term profitability. When evaluating RGL for trading indices like the US100, I immediately noticed several red flags that impact any cost assessment. Most importantly, RGL lacks any valid regulatory status and is flagged with high potential risk due to a suspicious scope of business. For me, this lack of regulation means that any published cost structure could be unreliable or subject to sudden changes, without client protection or regulatory recourse. Digging into the details, I found no transparent breakdown of trading costs for indices such as the US100 on RGL's materials. Unlike established, regulated brokers, RGL does not disclose spreads, commissions, or swap/overnight fees associated with index trading. Without this vital information, it's impossible for a prudent trader to accurately estimate the total transaction costs beforehand. I also noticed that RGL primarily operates as an Internet Service Provider and lists a range of IT services; there is no evidence of a professional trading platform or clear fee policy for financial instrument trading. Because costs in trading (like spreads and commissions) can significantly affect returns, the absence of clarity or regulatory oversight means I cannot recommend, or even confidently evaluate, the total trading expenses at RGL for an instrument like US100. From my perspective, unless fee transparency and regulatory assurances are established, the risks—including unknown or hidden costs—far outweigh any potential benefits. I would proceed with the utmost caution and advise others to seek out licensed, reputable brokers for index trading.
