 However, even trades made within the three trade limit (the 4th being the one that would send the trader over the Pattern Day Trader threshold) are arguably going to involve higher risk, as the trader has an incentive to hold longer than he or she might if they were afforded the freedom to exit a position and reenter at a later time.In this sense, a strong argument can be made that the rule (inadvertently) increases the trader's likelihood of incurring extra risk to make his trades "fit" within his or her allotted three-day trades per 5 days unless the investor has substantial capital.The rule may also adversely affect position traders by preventing them from setting stops on the first day they enter positions.
