determining account value on iphone app

When using the iphone trading app, what do I need to look at to determine the total amount of money in my account, if I also have margin debt?

I assumed the bold number in the upper right was my total account value. But if I am using margin do I need to substract my margin debt from that number to know how much money I currently have in my account?

What I want to be able to determine is the liquidation value of the account at any given moment.

Thanks for your help.

 

You didn't mention the broker.

 

sorry, thought this was the interactive brokers forum -

I'm referring to the IB iphone app

 

NLV-net Liquidation value. That's the bottom line. Means all debts are settled.

 

Great - that's what I thought, but wanted to make sure with the super volatile market action lately.

thanks for your reply.
