Seeking script to close all trades profit figure is achieved

Hi, I currently have a scalper EA running, however as I have multiple accounts, it is difficult for me to monitor them all. As such, I'm seeking a script to be created that will close all current open positions when the account reaches $400 profit for the month and turn off auto trading. For example, 1st of March starting balance is $1k....on march 10th the account balance is $1,405, however the running loss is $610, so script will not be triggered. On march 20th, the acount balance is 1800 and on the day, the running loss hits $400: 1800-400=1,400 (1k+400 profit), all trades are closed and auto trading is turned off
