No. You are not allowed to hold trades overnight.

All trades MUST be closed one (1) minute before the close of the market. Different instruments have different market closing times. It is the trader's responsibility to know these and close their positions before the respective market closes. Holding a position past 1 minute before the market closing time will result in your Evaluation or Elite account failure. Holding a position past the market close in your Elite account will result in a forfeit of profits with account closure.

Example: ES traders must close all positions before 3:59 pm Central Standard time on a normal market hours trading day. New trades are only permitted to open at 5 pm Central Standard time.

It is the trader's responsibility to know holiday trading hours that may vary.
