I guess as experienced traders, we all know that the market is not good during off business hours like after market closed off, weekends, or holidays. Sometimes, spiking in news releases are noise for long term traders as well or its too volatile and it can wipe out your account as well. So, these times should be avoid due to slow market movement and low demand and less transactions. However, you can get in on Sunday prior to market open on Monday to get the lowest price for the day.
