As an experienced trader, I prioritize understanding all broker-related fees, including potential inactivity charges, before committing any significant funds. After a thorough review of CHIEF, I did not find any explicit mention of inactivity fees in the available information. The broker provides clear details on trading commissions and minimum charges for various types of transactions—such as online, phone, and grey market trades—but there’s no specific indication that they levy fees simply for maintaining a dormant account. However, I am always cautious, particularly with brokers that don't publish a complete schedule of all possible account fees in easily accessible places. My experience tells me that some brokers reserve the right to introduce or apply inactivity fees, especially if an account remains unused for an extended timeframe. In the absence of direct information, I would always recommend potential clients to read the full terms of service and even contact CHIEF's customer support for absolute clarity on this issue before proceeding. In summary, I have not encountered any inactivity fees with CHIEF based on the public information, but I never assume the absence of such fees unless explicitly confirmed. Diligence here is especially important, since even seemingly minor fees can add up or catch traders by surprise. That’s why I always seek written confirmation from the broker before leaving any account inactive for long stretches.
