# Troubleshooting
Run `verify_setup` first — it checks all paths and returns actionable hints.
## Wine Not Found
### macOS
Confirm `/Applications/MetaTrader 5.app` exists and has been launched at least once.
Check detection:
```bash
bash scripts/platform_detect.sh
```
If using CrossOver, confirm bottle is named `MetaTrader5`.
### Linux
```bash
sudo apt install wine64 # Debian/Ubuntu
sudo dnf install wine # Fedora/RHEL
which wine64 # confirm on PATH
```
## terminal64.exe Missing
MT5 unpacks `terminal64.exe` only after first launch.
1. Open MetaTrader 5.app
2. Wait for initialization (~30s)
3. Quit
4. Re-run setup:
```bash
bash scripts/setup.sh --yes
```
## MCP Server Not Appearing
### Claude Code
```bash
claude mcp list # should show MT5-Quant
claude mcp remove MT5-Quant # remove stale entry
claude mcp add MT5-Quant -- /absolute/path/to/mt5-quant
```
**Must use absolute path** — relative paths break when Claude starts from different directories.
### Windsurf
1. Check logs: `~/.windsurf/logs/`
2. Verify executable path is absolute
3. Test manually: `./mt5-quant --help`
## Config Not Found
Set `MT5_MCP_HOME` or ensure config exists at:
- macOS: `~/.config/mt5-quant/config/mt5-quant.yaml`
- Project: `config/mt5-quant.yaml`
## Report Not Found After Backtest
1. **Wrong symbol name** — brokers use custom names (`XAUUSDm`, `XAUUSD.cent`). Check `verify_setup` or look in `<terminal_dir>/history/`.
2. **No history data** — open MT5, open symbol chart, wait for history download.
3. **EA crash at startup** — check `<terminal_dir>/MQL5/Logs/` for `OnInit` errors.
4. **Date range has no trades** — try wider range or confirm symbol was active.
## MetaEditor Compile Errors
Check `<terminal_dir>/MQL5/Logs/`:
- **Missing `#include`** — copy dependencies into `Experts/` alongside `.mq5`
- **Stale `.ex5`** — delete old binary and recompile
## No Deals in Backtest Report
- Use `model=0` (every tick) — models 1/2 skip intra-bar movement, producing zero deals for grid/martingale EAs
- Check `.set` file values appropriate for symbol/broker
- Confirm `OnInit()` returns `INIT_SUCCEEDED` (MT5 Journal tab)
## Analytics Tools: "No reports in DB" or "Report not found"
Analytics tools load deals from the **SQLite database**, not from CSV files on disk. Resolution order:
1. `report_id` (preferred) — ID from `list_reports`
2. `report_dir` (legacy) — filesystem path, looks up matching DB entry
3. No args — uses the latest report automatically
Pre-DB reports (before this version) won't be found by `report_dir`. Re-run the backtest to get a DB-backed report.
**`deals.csv` is no longer written automatically.** Call `export_deals_csv` to generate one on demand:
```
export_deals_csv() # latest report → report_dir/deals.csv
export_deals_csv(report_id: "20260422_…") # specific report
export_deals_csv(output_path: "/tmp/out.csv") # custom path
```
## Optimization Never Finishes
```bash
# From Claude:
tail_log(job_id=X, filter=errors)
get_optimization_status(job_id=X)
```
If MT5 crashed, edit `<terminal_dir>/terminal.ini` and remove line containing `OptMode=-1`, then retry.
## Permission Denied
```bash
chmod +x /path/to/mt5-quant
```
## Still Stuck?
1. Run `verify_setup` and share output
2. Check `tail_log` for errors
3. Review `<terminal_dir>/MQL5/Logs/` for EA errors
