A day trader may wish to hold a trading position overnight either to reduce losses on a poor trade or to increase profits on a winning trade. Generally, this is not a good idea if the trader simply wants to avoid booking a loss on a bad trade. Risks involved in holding a day trading position overnight may include having to meet margin requirements, additional borrowing costs, and the potential impact of negative news. The risk involved in holding a position overnight could outweigh the possibility of a favorable outcome.
