Based on my review and experience in assessing brokers, understanding the complete cost structure is crucial before considering trading indices like the US100 on RICO. What stands out immediately for me is that RICO is unregulated and flagged as high risk, which, from my perspective, already demands extra caution. In regulated environments, trading costs are generally well-disclosed and somewhat standardized. However, with RICO, the breakdown is far less transparent. The primary trading costs for indices like the US100 on RICO are composed of both platform fees and any embedded trading costs (such as spreads or commissions). RICO offers several platforms, but some, including Tradezone Desktop and TraderEvolution Desktop, carry fixed monthly fees—R$60 and R$160, respectively—while others like RicoTrader and Tryd Pro also incur ongoing charges. On top of that, there’s a mandatory ISS tax of 10.68% added to those fees. For me, these platform charges are quite significant, especially compared to brokers where platforms are often free. What isn’t clearly detailed by RICO is the specific spread or commission per trade for indices such as the US100. That lack of transparency is a major red flag in my experience; it means I wouldn’t be able to estimate my total trading costs reliably. Between recurring platform fees, additional taxes, and uncertain on-trade charges, the true cost of trading indices on RICO could easily outweigh any potential benefits, especially when safer, more transparent alternatives exist. For me, the combination of high fixed costs and regulatory uncertainty makes this broker an unattractive choice for index trading.
