SWING TRADING

I was recently taken out of a position that I intended to hold for several days, but it was automatically closed around 3 PM the next day. Support told me they don’t allow swing trades due to their risk parameters, but I don’t understand how that makes sense when I had both a stop-loss and take-profit set. I feel I should be able to trade in the way that works best for me and hold positions for as long as I choose. My goal is to be profitable, and if swing trading is what makes me profitable, I believe I should be allowed to use that strategy.
