As an experienced trader always mindful of risk, I approach trading cost evaluations with caution, especially with platforms that raise red flags. Based on what I’ve gathered about Robinhood, it’s clear that trading traditional indices like the US100 (NASDAQ 100) is actually not available—Robinhood does not currently support trading of indices, whether through CFDs or spot products. Their offering is limited to stocks, options, cryptocurrencies, and some futures, and there is no mention of index trading like US100 on their platform. If hypothetically I wanted to explore index-related exposure at Robinhood, it would have to be through ETFs that track major indices, but, again, the context makes it clear these are not available on this platform. While Robinhood prides itself on commission-free trading for the products it does offer, it’s vital to recognize the absence of regulatory oversight and repeated, serious withdrawal issues reported by users. For me, this lack of transparency and user protection outweighs any advertised cost benefits. Even if zero commissions are advertised, hidden risks—such as withdrawal blockages and questionable request for anti-money laundering deposits—could cost far more than typical trading fees. In conclusion, not only is trading the US100 or any indices directly impossible on Robinhood, but the risks and unclear business practices make it an unsuitable and unsafe environment, in my view, even if such products became available.
