Unrealized pips

How do you calculate unrealized pips. And could someone also give me the exact time of when the market closes on Friday and when the market opens on sunday. thanks

Unrealized is just how many you have lost/made, but you are still in an open position. usually there is somewhere on the platform where you can monitor what trade you are in, so you can see how much you have made or lost. Look for an open position window. I know that the market opens at 5:15pm EST on Sunday, not sure of exact close on Friday though.
