Does anyone know about the daily SEC fees charged by Tradestation ? Each day my beginning balance is several dollars less than my closing balance of the prior day even though I don't have any overnight positions. Upon questioning the Tradestation folks, they tell me these are SEC fees. I figure they are costing me about $90 / mo in addition to the $100 usage fee charged by Tradestation. I have never seen any mention of SEC fees in TradeStation advertising or in any disclosure. What's the story ?
