Advice on listing a system

Can anyone enlighten?

The system I’m hoping to list on C2 trades stock. I would just like to know what would happen if I wanted to enter my signal on C2 before the markets had opened at say 5am? i.e. would the order be placed at the first available time/price once the market had opened or is it not possible to enter a signal at unsociable hours?!


You have choices to do whatever you want.


You can enter the signals at any time of day or night. If markets are not open, the order will be submitted at the official stock market open.
