Set the alarm for 9:00pm. Thought I couldn't break 4100 after hitting 4114 twice, set a stop loss at 4081 and went to sleep. Woke up and saw my position was gone, considering the fees, I lost 5000u. I really can't sleep with an open position; every time I wake up, my position is gone, without exception. Maybe I can only profit by doing very short-term trades based on events. I still lack experience with contracts. I'll take it slow and focus on events to make a comeback.
