EA to close positions, orders and EAs

I trade in my MT5 account with Experts Advisors. The job I am offering consists in creating another EA to automatically check my account equity and take actions if it reaches a certain level.

Its would have only one input: account equity.

If at any given time the account equity is lower than the value defined in the input box, the EA would take the following actions:

-Remove all other EAs from its operations;

-Close all open positions (losing and winning ones);

-Close all open orders

After performing this action, the EA would post information via webrequest to inform me this was done.
