My brain tells me that some of these profits are likely at my own trades&amp;#x27; expense, and that while markets and economies rise and fall, my own profits are negatively impacted by HFT.&lt;p&gt;That may not be accurate, but that&amp;#x27;s why I personally feel uncomfortable with HFT.</text></comment>
