## Automatic Daily Updates

### Option 1: Windows Task Scheduler (Recommended)

#### Step 1: Create Batch File Wrapper

Create `run_scraper.bat` in the oi_scraper directory:

```cmd
@echo off
cd /d C:\Users\YourUsername\Gitea\MeanRevisionEA\oi_scraper

echo Starting CME OI Scraper at %date% %time% >> scraper.log
echo ---------------------------------------- >> scraper.log

python main.py >> scraper.log 2>&1

if %ERRORLEVEL% EQU 0 (
    echo %date% %time%: Scraper completed successfully >> scraper.log
) else (
    echo %date% %time%: Scraper failed with error %ERRORLEVEL% >> scraper.log
)

echo ---------------------------------------- >> scraper.log
```

Replace `YourUsername` with your actual username.

#### Step 2: Open Task Scheduler

Press `Win + R`, type `taskschd.msc`, press Enter

Or: Start → Windows Administrative Tools → Task Scheduler

#### Step 3: Create Task

1. Click **"Create Basic Task"** on right sidebar
2. **Name:** `CME OI Scraper - Daily`
3. **Description:** `Update OI data from CME QuikStrike every day at 9 AM`
4. Click **Next**

#### Step 4: Set Trigger

1. **Trigger:** Select "Daily"
2. **Start date:** Today's date
3. **Start time:** 9:00:00 AM (or your preferred time)
4. Click **Next**

#### Step 5: Set Action

1. **Action:** Select "Start a program"
2. **Program/script:** 
   ```
   C:\Users\YourUsername\Gitea\MeanRevisionEA\oi_scraper\run_scraper.bat
   ```
3. **Start in (optional):** 
   ```
   C:\Users\YourUsername\Gitea\MeanRevisionEA\oi_scraper
   ```
4. Click **Next**

#### Step 6: Finish

1. Review settings
2. Check "Open the Properties dialog for this task when I click Finish"
3. Click **Finish**

#### Step 7: Configure Advanced Settings (Optional)

In the Properties dialog:

- **General tab:**
  - ✅ Run whether user is logged on or not
  - ✅ Do not store password (if using Windows authentication)
  - ✅ Run with highest privileges

- **Conditions tab:**
  - ✅ Start the task only if the computer is on AC power
  - ✅ Stop if the computer switches to battery power
  - ✅ Wake the computer to run this task

- **Settings tab:**
  - ✅ Allow task to be run on demand
  - ❌ Stop the task if it runs longer than: 30 minutes
  - ✅ If the task fails, restart every: 5 minutes (up to 3 times)

Click **OK** to save settings.

#### Step 8: Test Task

1. In Task Scheduler, find "CME OI Scraper - Daily"
2. Right-click → **Run**
3. Check `scraper.log` after a minute:
   ```cmd
   type scraper.log
   ```

---

### Option 2: PowerShell Script (Advanced)

#### Step 1: Create PowerShell Script

Save as `run_scraper.ps1`:

```powershell
# Script configuration
$scriptPath = "C:\Users\YourUsername\Gitea\MeanRevisionEA\oi_scraper"
$logFile = "$scriptPath\scraper.log"
$timestamp = Get-Date -Format "yyyy-MM-dd HH:mm:ss"

# Navigate to script directory
cd $scriptPath

try {
    # Run Python scraper
    Write-Output "$timestamp: Starting CME OI Scraper" | Add-Content $logFile
    & python main.py *>> $logFile 2>&1
    
    # Check if CSV was created
    if (Test-Path "oi_data.csv") {
        $fileInfo = Get-Item "oi_data.csv"
        Write-Output "$timestamp: Scraper completed successfully (CSV updated: $($fileInfo.LastWriteTime))" | Add-Content $logFile
    } else {
        Write-Output "$timestamp: WARNING - CSV file not created" | Add-Content $logFile
    }
} catch {
    $errorMsg = $_.Exception.Message
    Write-Output "$timestamp: ERROR - $errorMsg" | Add-Content $logFile
    exit 1
}
```

#### Step 2: Update Task Scheduler to Use PowerShell

Same steps as Option 1, but:

- **Program/script:** `powershell.exe`
- **Add arguments:** 
  ```
  -ExecutionPolicy Bypass -File "C:\Users\YourUsername\Gitea\MeanRevisionEA\oi_scraper\run_scraper.ps1"
  ```

## MetaTrader 5 Integration

### Find MT5 Files Directory

MT5 data directory location:

```
C:\Users\YourUsername\AppData\Roaming\MetaQuotes\Terminal\[Terminal_ID]\MQL5\Files\
```

**To find your Terminal_ID:**

1. Open MT5
2. Click **File** → **Open Data Folder**
3. Navigate to `Terminal\[Your_Terminal_ID]\MQL5\Files\`

### Update Batch File to Copy to MT5

Edit `run_scraper.bat`:

```cmd
@echo off
cd /d C:\Users\YourUsername\Gitea\MeanRevisionEA\oi_scraper

echo Starting CME OI Scraper at %date% %time% >> scraper.log
echo ---------------------------------------- >> scraper.log

python main.py >> scraper.log 2>&1

if %ERRORLEVEL% EQU 0 (
    if exist oi_data.csv (
        echo Copying OI data to MT5... >> scraper.log
        copy oi_data.csv "C:\Users\YourUsername\AppData\Roaming\MetaQuotes\Terminal\[Your_Terminal_ID]\MQL5\Files\oi_data.csv"
        
        if %ERRORLEVEL% EQU 0 (
            echo %date% %time%: Scraper completed - OI data copied to MT5 >> scraper.log
        ) else (
            echo %date% %time%: ERROR - Failed to copy to MT5 >> scraper.log
        )
    ) else (
        echo %date% %time%: ERROR - oi_data.csv not found >> scraper.log
    )
) else (
    echo %date% %time%: ERROR - Scraper failed with error %ERRORLEVEL% >> scraper.log
)

echo ---------------------------------------- >> scraper.log
```

Replace `[Your_Terminal_ID]` with your actual MT5 terminal ID.

### Update EA Configuration

In your EA (`OI_MeanReversion_Pro_XAUUSD_A.mq5`), set:

```mql5
input ENUM_OI_SOURCE InpOISource = OI_SOURCE_CSV_FILE;  // Load from CSV file
```

The EA will automatically read `oi_data.csv` from its Files directory.

## Troubleshooting

### Python Not Found

**Error:** `'python' is not recognized as an internal or external command`

**Solutions:**

1. Use full path to Python:
   ```cmd
   C:\Users\YourUsername\AppData\Local\Programs\Python\Python312\python.exe main.py
   ```

2. Use `py` launcher:
   ```cmd
   py main.py
   ```

3. Reinstall Python with "Add to PATH" option

### Module Import Errors

**Error:** `ModuleNotFoundError: No module named 'playwright'`

**Solution:**
```cmd
pip install -r requirements.txt
```

### Login Fails

**Error:** `Login failed - still on login page`

**Solutions:**

1. Check credentials in `.env` file:
   ```cmd
   notepad .env
   ```

2. Check login screenshots:
   - `login_failed.png` - Shows login page
   - `login_error.png` - Shows error during login
   - `login_success.png` - Confirms successful login

3. Manually test login at: https://www.cmegroup.com/

4. Check if 2FA is required (CME may require additional authentication)

### No Data Extracted

**Warning:** `No CALL OI data extracted` or `No PUT OI data extracted`

**Solutions:**

1. Check if you're logged in:
   - Delete `cookies.json` to force fresh login
   - Run scraper manually with `HEADLESS=false` in `.env`

2. Check if page structure changed:
   - View screenshots to see actual page content
   - Check if Gold product URL is correct

3. Increase timeout:
   ```env
   TIMEOUT_SECONDS=60
   ```

### Task Not Running

**Issue:** Task Scheduler doesn't execute the task

**Solutions:**

1. Check task history:
   - Task Scheduler → Right-click task → Properties → History tab
   - Look for errors in the log

2. Test manually:
   - Right-click task → Run
   - Check `scraper.log` for output

3. Check account permissions:
   - Ensure task is set to run with your Windows account
   - Check "Run whether user is logged on or not"

4. Check Windows Event Viewer:
   - Event Viewer → Windows Logs → Application
   - Look for Task Scheduler errors

### Session Expiration

**Issue:** Session expires after some time

**Solution:**
The scraper will automatically re-login when cookies expire. No manual action needed.

To force fresh login:
```cmd
del cookies.json
```

### Check Logs

**View recent logs:**

```cmd
type scraper.log | more
```

**View last 20 lines:**

```cmd
powershell "Get-Content scraper.log -Tail 20"
```

**Search for errors:**

```cmd
findstr /C:"ERROR" scraper.log
```

### Verify CSV Output

**Check if CSV is valid:**

```cmd
python -c "import pandas as pd; print(pd.read_csv('oi_data.csv'))"
```

**Check file size:**

```cmd
dir oi_data.csv
```

---

## Advanced Options

### Run Multiple Times Per Day

**Edit Task Scheduler Trigger:**

1. Open task properties → Triggers tab
2. Edit existing trigger → Click "New" to add additional
3. Set different times:
   - 9:00 AM
   - 12:00 PM
   - 3:00 PM
   - 6:00 PM

### Run on Market Days Only

**Create separate batch file:**

```cmd
@echo off
cd /d C:\Users\YourUsername\Gitea\MeanRevisionEA\oi_scraper

REM Check if today is weekday (1=Monday, 5=Friday)
for /f "skip=1 tokens=*" %%a in ('wmic path win32_localtime get dayofweek /value') do set DAY=%%a

if %DAY% LSS 1 goto END
if %DAY% GTR 5 goto END

REM Run scraper
python main.py >> scraper.log 2>&1

:END
```

### Email Notifications

**Use PowerShell to send email on completion:**

```powershell
# Add to run_scraper.ps1 at the end
$smtpServer = "smtp.gmail.com"
$smtpPort = 587
$smtpUser = "your_email@gmail.com"
$smtpPass = "your_password"
$from = "CME OI Scraper <your_email@gmail.com>"
$to = "your_email@gmail.com"
$subject = "CME OI Scraper - %date%"

if ($errorOccurred) {
    $body = "CME OI Scraper failed. Check logs for details."
} else {
    $body = "CME OI Scraper completed successfully.`n`nUpdated files:`n- oi_data.csv"
}

$message = New-Object System.Net.Mail.MailMessage $from, $to
$message.Subject = $subject
$message.Body = $body

$smtp = New-Object System.Net.Mail.SmtpClient $smtpServer, $smtpPort
$smtp.EnableSsl = $true
$smtp.Credentials = New-Object System.Net.NetworkCredential $smtpUser, $smtpPass

$smtp.Send($message)
```
