Accessing Terminal Data - HELP PLS

 
Hello

I am building an EA and also want to have graphics that display some of what is going on as a result of the trade being placed by EA.
I have the graphics sorted and was wondering what is the most efficient manner to access information that you would normally see in the Terminal like - Balance, Profit/Loss, Current trade (is it a buy or sell and how many lots?), current price, spread and so forth. Code would then place into my graphics and it would be displayed on screen

Can somebody kindly post code that would demonstrate this function?

Many thanks for your help.
