It all depends on trader`s psychology. Someone prefers to close all positions before the end of the day to avoid exposing to overnight risks, other traders prefer overnight (swing) trading as it is less time consuming.
By the way, there are several ways of understanding the term “swing trading”. Depending on situation it could mean:
– trading inside the mid-term range – for example, when the trader opens position near the support kevek and covers it near the resistance holding overnight.
– fundamental overnight trades based on fundamental ideas aimed to hold the position during the trend movement caused by that news.
