# 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

Install Wine 7.0+ and confirm on PATH:
```bash
# Debian/Ubuntu
sudo apt install wine64
# Fedora/RHEL
sudo dnf install wine
which wine64
```

Ask your LLM platform to install Wine if it's missing.

## 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.

## Backtest Completes But Always Shows "journal-only" (No HTML Report)

**Symptom:** Every backtest produces `status: completed_no_html` and all deal profits are `0.0`.

**Cause:** On Wine/macOS, `ShutdownTerminal=1` does **not** cause `terminal64.exe` to exit after the
test completes. The tester agent (MetaTester 5) closes normally, but the terminal process stays alive
indefinitely. Without process exit, MT5 never writes the HTML report.

**How the pipeline handles this:** The inactivity watchdog detects that the tester log has stopped
growing (test done), waits 30 seconds polling for the HTML file, then kills `terminal64.exe`
unconditionally. If the HTML appears during the wait it is extracted; otherwise journal extraction
provides deal counts and final balance (but no per-deal P&L).

**To maximise HTML report chances:** Pass `inactivity_kill_secs=120` explicitly (it is disabled by
default). With `shutdown=true` (default) this gives MT5 120s of quiet time + 30s of HTML-wait before
the kill.

```
launch_backtest(expert: "MyEA", shutdown: true, inactivity_kill_secs: 120)
```

**Fallback data available from journal:**
- Deal count, volume, prices, timestamps ✓
- Final balance (pips) ✓
- Per-deal profit/loss ✗ (always 0.0)
- Win rate, profit factor, Sharpe, drawdown ✗ (require HTML)

## `list_deals` Returns 0 Filtered Results

Analytics tools filter deals with `is_closed_trade()` which checks `entry = "out"`. If all deals
show `entry = "in"`, the position tracker that infers direction from signed lot accumulation may
not have run (old binary in memory).

**Fix:** Restart the MCP server (restart Claude Code / your IDE) after installing a new binary.
The server process caches the binary in memory — `install` doesn't hot-reload it.

## 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
