⚠️ CRITICAL SETUP INSTRUCTIONS FOR USERS

This EA communicates securely with Google servers. MT5 will block it by default unless you explicitly allow the connection.

Step 1: Whitelist the WebRequest URLs

1. In MT5, press Ctrl + O (Tools -> Options).

2. Go to the Expert Advisors tab.

3. Check the box for "Allow WebRequest for listed URL".

4. Add these two exact URLs:

Step 2: Install the Google Sheets Backend (Auto-Setup)

This EA requires a Google Apps Script to function as the "brain."

1. Create a blank Google Sheet.

2. Click Extensions > Apps Script.

3. Paste the JavaScript code provided at the bottom of this description.

4. Click Deploy > New Deployment (Select Web App, Execute as "Me", Access: "Anyone").

5. Copy the Web App URL and paste it into the EA's GoogleSheetWebAppURL input parameter in MT5.

6. Magic Setup: Within 60 seconds of attaching the EA, the script will automatically format your blank Google Sheet, build the Dashboard, and set up the Commands tab.
