Open Order Switching (from Buy to Sell and Sell to Buy)

[Kien]

Hi All, 

I have been searching high and low and cannot find...An EA or Script that allows for switching an existing open order from "Buy" to "Sell" (ie. "Buy" order is closed and "Sell" order is entered into) and vice versa.

Therefore..> at a press of a button...

ie. 

A) an existing open trade "Buy" closes and simultaneously execute a new "Sell" trade (with all the same but opposite parameters - ie. SL/TP, order size), and,

B) an existing open trade "Sell" closes and simultaneously execute a new "Buy" trade (with all the same but opposite parameters - ie. SL/TP, order size)

I would really appreciate it if someone out there knows of such tool or EA for MT4 and MT5

Kind regards.
