P/L Curve from pos from MT4 into Excel

Good day,
I have linked my MT4 with Excel using DDE, so I have live data in excel which is helpful but I need to somehow link an open position to excel and then use PL from that to draw a curve(line graph) in that spreadsheet.
I wonder is anyone could help me
Thank you a lot,
Slavo

This may not be what you initially asked for because it does not use excel, but judging from your question it looks like you simply want to visualize the floating profit in realtime. If you just want to see this curve and don't want to do any further calculations with it then maybe the "equity recorder" on mql4.com in the libraries section may be helpful to you.
