Enable/Disable external EA

Hi,

I have an EA, ex4 only - no code. I want this EA to run on specific times only but the EA doesn't support this.

Is there any way to enabling and disabling an EA problematically from another EA/script? I don't even care using an external windows application that simulates a press on the "Auto Trading" button to do this (as this is the only EA I run in this terminal)

Thanks
Yaniv

Hello,

This EA doesnot manage orders?

Depending on how this EA works, you'll need to be careful that you don't interrupt its trade management by disabling AutoTrading when there are open positions. Or other unforeseen consequences.

There is no clean way of doing this. You can play around with applying templates, but probably the easiest way is to send the keystrokes CTRL+E (that toggles Autotrading on/off)

Inserted Code
#import "user32.dll"
    void keybd_event(int bVk, int bScan, int dwFlags,int dwExtraInfo);
#import
#define  REL  0x0002
#define  CTRL 0x11
#define  E    0x45

Inserted Code
   keybd_event(CTRL,0,0,  0);
   keybd_event(E,   0,0,  0);
   keybd_event(CTRL,0,REL,0);
   keybd_event(E,   0,REL,0);

There are 2 different things: prevent autotrading or stpo EA on running.
You can prevent autotrading but EA is still running , but impossible to start, stop, modify entries.
If you will allow autotrading later, EA starts processing of the orders,
but without knowledge of the logic, impossible to be sure on correct behaviour.

Hello to all, I have an existing custom indicator that currently disables Autotrading and enable it again after a specied amount of time. It was design for News events.

I am not a programmer and will very much appreciate it if someone could do a slight modification on it so it can have a couple more options.

1. Option of choosing only high impact news
2. Option of disabling Autotrading by user entering a specified time ie: during Asian session, before disabling Autotrading indicator to first check if all orders are closed.

Below I have attached the mql file.

Thank you in advance,
Brian M
