Excel Auto trade project

I want to build excel file-1 showing the live forex rates and passing my orders to my demo account. I got my signal as another excel file-2 each 10 minutes and I need this excel file to be open and taken the signals from it and closed(from my local network), then those signals passed to my demo account, the orders to be entered as waited order or open position if needed. The excel file-1 having many pages, each page for different purposes, one page for summary another for others. I need experienced coder to do this project who have previous experiences in such project.

I want excel file to watch my mt4 account live forex rates values live

and passing my orders to my mt4 account.

this might be done by DDE or vba code inside excel,

this project is to run one mt4 account only.

I need the lot size is the main controller,
lot size= LS= 0.1  this will let excel to pass order to open buy position of lot size 0.1,
if LS=-0.1  then open sell position of lot size 0.1,
if there is existing position then do nothing.
I want to make this project simple for you.
either buy or sell should be passed to mt4 in a specific value in near column.
So my buy or sell order executed only at this price value or better, and not executed in market values.
my real account is with go markets mt4, I wish to try your excel file in my real life account.
Lot size is 1.0 this is regular contract (1 pip = 10 usd)
Lot size is 0.1 is small contract (1 pip = 1 usd)

I want to see all the details of my forex live account in the excel page, for example: capital , earning , no. of open positions , daily loss and daily profit, no history data needed to be shown here, show me the history of my trades over the last day or week or month.
