Add a setting to a script.stop trading if balance low

Background: I have a script that is a Trade Copier that sends a manual or EA trade to a differant screen or MT4 platform on the same pc. What is required: I need to have a small bit of script added so that the trades do not function if the balance goes below a given amount. This amount should be able to be changed by user. Winning bid: I would like to test it on my demo account. I will send the script to the winning bidder for adjusting.
