🔧 Troubleshooting

❌ EA not responding / Timeout errors

Solutions:

1. Check the EA is attached to a chart (you should see 😊)

2. Enable AutoTrading in MT5 (Ctrl+E)

3. Check Experts log in MT5 for errors

4. Try removing and reattaching the EA

❌ "MT5 initialization failed"

Solutions:

1. Verify MT5 is installed: C:\Program Files\MetaTrader 5\terminal64.exe

2. Open MT5 at least once to initialize

3. If custom install path, set MT5_PATH environment variable

❌ Screenshot file not found

Solutions:

1. Ensure EA is running (check for 😊 on chart)

2. Check Experts log for errors

3. Verify AutoTrading is enabled

4. Try capturing a chart that's already open

❌ "Could not fetch data for symbol"

Solutions:

1. The symbol must exist in your MT5 (check Market Watch)

2. Symbol names are case-sensitive

3. Try with "EURUSD" first to test

❌ Encoding errors / Garbled text

Solution: This is fixed! The system uses UTF-16 LE encoding for EA communication.
