Troubleshooting Copy Trading
Solutions to common copy trading issues and problems.
Connection Issues
Group Won't Connect
If your copy trading group status shows "Error" or keeps showing "Connecting":
- Check API credentials - Verify your API Key and Secret are correct
- Verify permissions - Ensure the API has Futures Trading permission
- Check for IP restrictions - Remove IP restrictions or add server IPs
- Try regenerating - Create new API credentials and update
Frequent Disconnects
If the connection drops frequently:
- MEXC may be experiencing issues - check their status page
- Network instability - check your internet connection
- API rate limits - wait and let the auto-reconnect handle it
Auto-Reconnect
Copy trading automatically reconnects if the connection drops. It uses exponential backoff to avoid overwhelming the server.
Position Issues
Position Not Copied
If a master position wasn't copied to followers:
- Check connection - Was the group connected when the trade happened?
- Check follower status - Is the follower enabled?
- Check margin - Did the follower have sufficient balance?
- Check logs - Look for error messages in activity logs
Follower Failed to Execute
When a specific follower fails:
- Insufficient margin - Add funds to the follower account
- Position limit - Account may have hit position limits
- Reduce copy ratio - Lower the ratio for that follower
- Check account status - Verify the account is valid
Partial Execution
If only some followers executed:
- Check each failed follower's error message in the logs
- Each follower executes independently
- One failure doesn't affect others
SL/TP Issues
SL/TP Not Copied
- Check setting - Is "Copy SL/TP" enabled for the group?
- Timing - SL/TP might be created slightly after position opens
- Check logs - Look for SL/TP creation entries
SL/TP Triggered at Different Times
This is normal behavior:
- SL/TP orders execute independently on each account
- Slight price differences may cause different trigger times
- Network latency affects execution timing
Performance Issues
Slow Copying
If copies seem delayed:
- WebSocket updates are typically instant (milliseconds)
- Execution depends on MEXC API response time
- Many followers may take slightly longer
- Check if connection status is "Connected"
Missed Trades During Disconnection
If trades were missed while disconnected:
- Positions opened during disconnection are not copied
- You'll need to manually open on followers
- Future trades will copy once reconnected
No Historical Sync
Copy trading only copies trades that happen while connected. It does not synchronize historical positions or positions opened during disconnection.
