He was complaining about a rule that makes no sense. Would you get ride of a very profitable trader who makes you money because of one silly rule breaking? Also, even if you don't want overnight trading, why not just kick every trader out of position at the end of the day? IS automatization so hard for these firms? The stupid rules are there so nobody stays on the "live" account for too long, because that is the firm's money, aka they are bucketshops. Glad to inform you about real life.
