+# AGENTS.md — Developer instructions for MT5-Quant
+
+## Project Overview
+
+Open-source MCP server for MetaTrader 5 backtesting, optimization, and analytics — written entirely in Rust. Exposes 89 stdio MCP tools for compiling MQL5 EAs, running backtests via Wine, extracting deal-level data, organizing reports in SQLite, and performing 19 dimensions of analysis.
+
+Target users: MQL developers on macOS (CrossOver or native MetaTrader5.app) and Linux (Wine/Xvfb).

+
+## Key Design Constraints
+
+- **Headless/GUI**: `platform_detect.sh` auto-selects. macOS CrossOver = GUI (CrossOver abstracts display). Linux without `$DISPLAY` = Xvfb. Controlled by `display.mode` in config (`auto` | `gui` | `headless`).
+- **Single MT5 instance**: Never run two backtests in parallel on the same Wine prefix.
+- **Model 0 only for optimization**: Model 1 overfits martingale/grid EAs — intra-bar movement not simulated. Use `model=0` (every tick).
+- **UTF-16LE .set files**: MT5 strips `||Y` flags from UTF-8. All `.set` writes use UTF-16LE + `chmod 444`. See `setfiles.rs` helpers.
+- **OptMode reset**: After any optimization, `terminal.ini` gets `OptMode=-1`. Must reset to `0` before next backtest (handled in `backtest.rs` cleanup stage).
+- **Report format detection**: MT5 Build 48+ writes SpreadsheetML XML (`.htm.xml`), not HTML. Both formats handled in `extract.rs` — always check for the XML variant first.
+- **EA-agnostic**: Never hardcode magic numbers, strategy names, or assume specific EA behavior. All code must work with any MQL5 EA.
+
+## Architecture
+
+1. **CLI (`main.rs`)** — parses CLi args (`--stdio`, `--port`, `--test-launch`), initializes `McpServer`, runs stdio or TCP transport loop, handles JSON-RPC requests.
+
+2. **McpServer (`mcp_server.rs`)** — wraps `ToolHandler` with `Arc<Mutex>`, handles `initialize`/`notifications`/`tool/error` method routing. Auto-verifies Wine/MT5 on first call.
+
+3. **ToolHandler (`tools/handlers/mod.rs`)** — dispatch table mapping 89 tool names to handler functions. Each handler module is self-contained.
+
+4. **Definitions (`tools/definitions/`)** — JSON Schema objects for tool input/output. Never executes logic.
+
+5. **Analytics (`analytics/`)** — two core structs:
+   - `ReportExtractor` — reads HTML/XML report + tester log → `Vec<Deal>` + `BacktestMetrics`
+   - `DealAnalyzer` — takes `Vec<Deal>` → 19 analysis methods (monthly PnL, drawdown events, streaks, etc.)
+
+6. **Pipeline (`pipeline/backtest.rs`)** — `BacktestPipeline` struct with 5 stages:
+   - `COMPILE` — `MqlCompiler::compile()` via MetaEditor
+   - `CLEAN` — clean cache, reset OptMode
+   - `BACKTEST` — launch MT5 tester via Wine, poll status
+   - `EXTRACT` — parse HTML/XML → deals + metrics
+   - `ANALYZE` — run all analytics, write to SQLite
+
+7. **Storage (`storage/database.rs`)** — `ReportDb` with two tables:
+   - `reports` — metrics, set file paths, verdict, tags, notes
+   - `deals` — individual deal rows, keyed by `report_id`
+   - `CREATE TABLE IF NOT EXISTS` in `init()` — idempotent on startup
+
+## Building
+
+```bash
+bash scripts/build-rust.sh
+# or
+cargo build --release
+```
+
+Binary: `target/release/mt5-quant`
+
+## Testing
+
+- **Unit/integration:** `cargo test`
+- **End-to-end MCP:** `python3 tests/test_mcp.py` — drives the MCP server over stdio (full backtest + all analytics)
+- **Analytics only:** No MT5/Wine needed; loads deals from SQLite DB via `db.get_deals(report_id)`
+- **Symbol note:** Testing account uses `XAUUSDc` (broker suffix required), not `XAUUSD`
+
+## Configuration
+
+Users copy `config/mt5-quant.example.yaml` → `config/mt5-quant.yaml` (gitignored).
+Run `bash scripts/setup.sh` to auto-detect Wine, MT5 paths, architecture, and write config.
+
+Minimum config:
+```yaml
+wine_executable: "/path/to/wine64"
+terminal_dir: "/path/to/MetaTrader 5"
+```
+
+Optional:
+```yaml
+defaults:
+  symbol: "XAUUSD.cent"
+  timeframe: "M5"
+  deposit: 10000
+display:
+  mode: auto               # auto | gui | headless
+reports_dir: "./reports"
+experts_dir: "~/.../MQL5/Experts"
+```
+
+## Developing New Tools
+
+Each new tool follows a 4-file pattern:
+
+1. **Schema** — Add tool input/output to `tools/definitions/{domain}.rs` via `Tool::new(name) {...}` with `Input::schema` and `Output::schema`.
+2. **Export** — Add to `tools/definitions/mod.rs`:
+   - Include in `all_tools()` array
+   - Add to domain exports if creating new domain
+3. **Handler** — Add function in `tools/handlers/{domain}.rs`:
+   ```rust
+   pub async fn handle_tool_name(config: &Config, args: &Value) -> Result<Value> {
+       let required = required_str(args, "param_name")?;
+       ok_response(json! { "result": "..." })
+   }
+   ```
+4. **Dispatch** — Add case in `handlers/mod.rs` match arm under `ToolHandler::handle()`.
+
+### Handler Helper Functions (use instead of inline logic)
+
+| Helper | Purpose |
+|--------|---------|
+| `required_str(args, key)` | Extract required `&str` or return error |
+| `ok_response(data)` / `err_response(msg)` | Wrap in MCP content envelope |
+| `resolve_report(args)` | → `(deals, metrics, report_dir)` — `report_id > report_dir > latest` |
+| `prepare_analysis(args)` | → `(deals, metrics, analyzer, report_dir)` — wraps resolve_report |
+| `scan_mql_dir(dir, filter, type_label)` | WalkDir with optional filter for list/search |
+| `copy_mql_to_project(config, args, fallback)` | Shared copy logic for indicator/script |
+
+Extend helpers when adding new handlers.
+
+## Commit Style
+
+Conventional commits: `feat:`, `fix:`, `docs:`, `refactor:`, `test:`, `release:`
+Keep commits focused — one logical change per commit.
+
+## Release Process
+
+```bash
+bash scripts/release.sh <patch|minor|major|X.Y.Z> [--yes]
+```
+
+Script handles:
+1. Bump `Cargo.toml` + `Cargo.lock` version
+2. Update `server.json` (version + SHA256 placeholder)
+3. Generate CHANGELOG entry from git log
+4. `cargo check --quiet`
+5. Commit `release: vX.Y.Z`
+6. Tag `vX.Y.Z`
+7. Push — CI (`release.yml`) triggered:
+   - Build macOS arm64 + Linux x64 binaries
+   - Publish to crates.io
+   - Create GitHub Release with artifacts
+   - Build MCP package, compute SHA256
+   - Update `server.json` SHA256, push
+   - Publish to MCP Registry
+
+## Deal Storage
+
+- Deals stored in `deals` SQLite table, keyed by `report_id`. **No `deals.csv` written automatically.**
+- `db.insert_deals(report_id, &[Deal])` called in pipeline after extraction.
+- `db.get_deals(report_id)` loads deals for analytics. `db.get_by_report_dir(path)` resolves by filesystem path.
+- `export_deals_csv` tool writes CSV on demand.
+
+## DB Schema Evolution
+
+Add new tables/columns in `ReportDb::init()` using `CREATE TABLE IF NOT EXISTS` / `CREATE INDEX IF NOT EXISTS` — runs on every startup, is idempotent. No migration files needed.
+
+## Wine / MT5 Notes
+
+- Wine executable paths differ across platforms:
+  - macOS MT5.app: `/Applications/MetaTrader 5.app/Contents/SharedSupport/wine/bin/wine64`
+  - macOS CrossOver: `/Applications/CrossOver.app/Contents/SharedSupport/CrossOver/bin/wine64`
+  - Linux: `/usr/bin/wine64` (or first `wine64` on PATH)
+- MT5 terminal_dir is auto-resolved from wine_executable path.
+- Apple Silicon: append `arch -x86_64` prefix for x86 Wine binaries (auto-detected).
+
+## Common Pitfalls
+
+- **M1/Memory issues**: Wine on Apple Silicon runs x86 via Rosetta 2. Watch memory pressure.
+- **Model mismatch**: Grid/martingale EAs need `model=0` (every tick). Model 1/2 will produce zero deals.
+- **Set file encoding**: Always use UTF-16LE with `chmod 444`. UTF-8 strips `||Y` flags.
+- **OptMode=-1**: Must clear after optimization. Handled in pipeline cleanup stage.
+- **Report not found**: Check `<terminal_dir>/history/` for correct symbol name (broker suffix matters: `XAUUSDc` vs `XAUUSD`).
+- **Journal-only backtest**: `ShutdownTerminal=1` doesn't exit MT5 on Wine. Inactivity watchdog (in `launch_backtest`) handles this with `inactivity_kill_secs` param.

 # Changelog

+## [1.34.0] — 2026-07-02
+
+- docs: update changelog and tool documentation for rolling backtest
+- feat: add rolling backtest and optimization improvements
+- fix: sync Cargo.lock, remove unused Agents config from optimizer
+- fix: sync Cargo.lock version, remove unused agents config from optimizer
+
+
+## [1.33.0] — 2026-06-25
+
+### Added
+- **`src/utils/` module**: shared `read_file_as_utf8` utility for UTF-16LE BOM detection, used across set file and config handlers.
+- **OS detection and diagnostics**: `utility.rs` gains `OsType` enum, `get_os_context`, `get_system_memory`, and `crossover_server_running` helper for better CrossOver diagnostics.
+- **Wine binary detection**: MT5.app and CrossOver now detect both `wine` and `wine64` binaries; Homebrew and Linux paths add `wine` alongside `wine64`.
+
+### Changed
+- **Optimizer launch mechanism**: rewritten from `/mt5mcp_backtest.ini` + `.bat` to `/config:` INI + shell script. Now patches `terminal.ini` directly with full optimization parameters and appends agent configuration — no longer relies on batch file or separate INI.
+- **Removed unused local agent config**: stripped the `[Agents]` section (4 entries with UUIDs/IPs/ports) from `terminal.ini` output — no local agent processes are used.
+- **OptMode reset**: removed as a separate step; now included inline in `terminal.ini` patching during optimizer startup.
+- **Wine prefix resolution**: changed from 2-parent to 3-parent traversal, matching the backtest pipeline's Wine prefix logic.
+- **Optimizer `/config:` INI**: now includes `Model=4` and `Period=M1` in the test-configuration passed via `/config:` flag (previously hardcoded in the older INI-based approach).
+- **Set file parsing**: parameter delimiter changed from `:` to `=` (matches actual MT5 .set format); `||Y` sweep param parsing rewritten to split on `||` for accurate range extraction.
+- **OptimizationParams**: `model` parameter removed (was hardcoded to `0` everywhere anyway; MT5 now defaults correctly).
+
+### Fixed
+- **Cargo.lock sync**: lockfile version field is now kept in sync with the release process.
+- **Set file cross-platform reading**: `.set` files are now read as UTF-16LE (with BOM) or UTF-8 regardless of platform, fixing potential encoding issues on macOS/Linux.
+- **Read-only set file overwrite**: handles pre-existing read-only files during `.set` write by removing them first.

 **Others** typically run on Windows using the [MetaTrader5 Python package](https://pypi.org/project/MetaTrader5/), providing full terminal operations. MT5-Quant fills the gap: **organizing backtest reports, extracting deal-level insights, and managing optimization workflows** — none of which MT5 or its Python API expose natively.

-## Why Rust
-
-**MT5-Quant is built entirely in Rust** — one static binary, zero dependencies, instant startup.
-
-| | Rust | Python/Node |
-|---|---|---|
-| **Startup** | ~10ms | 200–500ms |
-| **Deploy** | Single binary | venv + pip/npm |
-| **Memory** | <50MB, no GC pauses | Unpredictable spikes |
-| **Safety** | Compile-time guaranteed | Runtime exceptions |
-
-**Why this matters for trading:**
- **No garbage collection** — Process 100k+ deal rows without GC pauses during live analysis
- **Async via Tokio** — Handle multiple tool calls concurrently (poll status while streaming logs)
- **Cross-platform** — Same source compiles to native macOS arm64 and Linux x86_64
- **Type-safe pipelines** — MQL5 compilation, Wine path handling, SQLite queries: all checked at compile time
-
-## Quick Install
-
-### Option 1: Pre-built Binary (Recommended)
-
-```bash
-curl -L -o mt5.tar.gz https://github.com/masdevid/mt5-quant/releases/latest/download/mcp-mt5-quant-macos-arm64.tar.gz
-tar -xzf mt5.tar.gz
-bash scripts/setup.sh
-```
-
-### Option 2: Cargo Install (if you have Rust)

 ## Quick Start

+### Install MT5-Quant
+
+Ask your LLM coding platform to install and configure MT5-Quant:
+
+> "Please install mt5-quant. It's a Rust-based MCP server for MT5 backtesting at https://github.com/masdevid/mt5-quant. Run its `scripts/setup.sh` to auto-detect Wine and MT5 paths, register the MCP server, and configure everything."
+
+The LLM will:
+1. Download the pre-built binary (or `cargo build --release`)
+2. Run `scripts/setup.sh` to auto-detect Wine/MT5 and write config
+3. Register the MCP server with your coding platform
+
+### First Backtest
+
 ```
 Run a backtest on MyEA from 2025.01.01 to 2025.03.31
 ```

 The AI runs the full pipeline: compile → clean cache → backtest → extract → analyze.

-# Claude Desktop MCP Integration Setup
-
-## Quick Setup
-
-### Option 1: Install via MCP Registry (Recommended)
-
-Search for `mt5-quant` in Claude Desktop's MCP manager, or add directly to your config.
-
-### Option 2: Download Prebuilt Binary
-
-```bash
-# macOS (Apple Silicon)
-curl -L -o mt5-quant.tar.gz https://github.com/masdevid/mt5-quant/releases/latest/download/mt5-quant-macos-arm64.tar.gz
-tar -xzf mt5-quant.tar.gz
-
-# Linux (x64)
-curl -L -o mt5-quant.tar.gz https://github.com/masdevid/mt5-quant/releases/latest/download/mt5-quant-linux-x64.tar.gz
-tar -xzf mt5-quant.tar.gz
-```
-
-### Option 3: Build from Source
-
-```bash
-git clone https://github.com/masdevid/mt5-quant
-cd mt5-quant
-cargo build --release
-```
-
-## Configure Claude Desktop
-
-### Step 1: Open MCP Configuration
-
-Edit `~/Library/Application Support/Claude/claude_desktop_config.json` (macOS) or `%APPDATA%\Claude\claude_desktop_config.json` (Windows).
-
-### Step 2: Add mt5-quant
-
-```json
-{
-  "mcpServers": {
-    "mt5-quant": {
-      "command": "/absolute/path/to/mt5-quant"
-    }
-  }
-}
-```
-
-### Step 3: Reload and Verify
-
-1. Save the file
-2. **Restart Claude Desktop**
-3. In a new conversation, type: `What tools do you have access to?`
-4. The agent should list MT5 tools like `verify_setup`, `run_backtest`, etc.
-
-## Full Example Configuration
-
-```json
-{
-  "mcpServers": {
-    "mt5-quant": {
-      "command": "/Users/name/mt5-quant/mcp-server/bin/mt5-quant"
-    },
-    "github": {
-      "command": "npx",
-      "args": ["-y", "@modelcontextprotocol/server-github"],
-      "env": {
-        "GITHUB_PERSONAL_ACCESS_TOKEN": "${env:GITHUB_TOKEN}"
-      }
-    }
-  }
-}
-```
-
-**Path notes:**
- Prebuilt binary: `/Users/name/mt5-quant/mcp-server/bin/mt5-quant` (extracted from release tarball)
- Dev build: `/Users/name/mt5-quant/target/release/mt5-quant` (after `cargo build --release`)
-
-## Environment Variables
-
-Claude Desktop supports `${env:VAR_NAME}` syntax for environment variable substitution:
-
-```json
-{
-  "mcpServers": {
-    "mt5-quant": {
-      "command": "/Users/name/mt5-quant/mcp-server/bin/mt5-quant",
-      "env": {
-        "MT5_MCP_HOME": "${env:HOME}/.config/mt5-quant"
-      }
-    }
-  }
-}
-```
-
-## Verify Setup
-
-In a Claude Desktop conversation, type:
-
-```
-Run verify_setup
-```
-
-Expected output:
-```
-Wine:    /Applications/MetaTrader 5.app/.../wine64
-MT5 dir: ~/Library/Application Support/.../MetaTrader 5
-Display: gui
-Arch:    arch -x86_64
-```
-
-## Troubleshooting
-
-### "Tool not found" or server not appearing
-
-1. Double-check the absolute path in `claude_desktop_config.json`
-2. Ensure the binary has execute permissions: `chmod +x /path/to/mt5-quant`
-3. Restart Claude Desktop completely
-4. Check Claude Desktop logs: `~/Library/Logs/Claude/` (macOS)
-
-### JSON syntax errors
-
-1. Validate the JSON at [jsonlint.com](https://jsonlint.com)
-2. Ensure no trailing commas
-3. Use absolute paths (not `~` or relative paths)
-
-### Agent hallucinating tool parameters
-
-1. Verify the tool is available: "List your available MCP tools"
-2. Start a new conversation
-3. Be explicit: "Use the `run_backtest` tool with expert=MyEA"

-### Option B: Build from Source
+The LLM will handle:
+1. Download binary or `cargo build --release`
+2. Run setup script to auto-detect Wine and MT5 paths
+3. Write `config/mt5-quant.yaml` (gitignored)
+4. Register MCP server with your platform

-```bash
-git clone https://github.com/masdevid/mt5-quant
-cd mt5-quant
-bash scripts/build-rust.sh
-```
+## Minimal Config

-## 2. Install MetaTrader 5
+If manual config is needed, `config/mt5-quant.yaml` requires only:

-### macOS - MetaTrader 5.app (Free)
-
-1. Download from [metatrader5.com](https://www.metatrader5.com/en/download)
-2. Install to `/Applications`
-3. **Launch once** to initialize Wine prefix (~30s), then quit
-
-Auto-detected paths:
- Wine: `/Applications/MetaTrader 5.app/Contents/SharedSupport/wine/bin/wine64`
- MT5: `~/Library/Application Support/net.metaquotes.wine.metatrader5/drive_c/Program Files/MetaTrader 5`
-
-### macOS - CrossOver (Paid, Better Compatibility)
-
-1. Install [CrossOver](https://www.codeweavers.com/)
-2. Create bottle `MetaTrader5`
-3. Install MT5 inside bottle
-
-Auto-detected paths:
- Wine: `/Applications/CrossOver.app/Contents/SharedSupport/CrossOver/bin/wine64`
- MT5: `~/Library/Application Support/MetaQuotes/<hash>/drive_c/Program Files/MetaTrader 5`
-
-### Linux
-
-```bash
-# Debian/Ubuntu
-sudo apt install wine64 xvfb
-
-# Fedora/RHEL
-sudo dnf install wine xorg-x11-server-Xvfb
-
-# Install MT5
-wine64 MetaTrader5Setup.exe
-```
-
-MT5 location: `~/.wine/drive_c/Program Files/MetaTrader 5`
-
-## 3. Configure
-
-Run the setup script to auto-detect paths:
-
-```bash
-bash scripts/setup.sh          # interactive
-bash scripts/setup.sh --yes    # non-interactive (CI)
-```
-
-This creates `config/mt5-quant.yaml` (gitignored).
-
-Minimum config:
 ```yaml
-wine_executable: "/Applications/MetaTrader 5.app/Contents/SharedSupport/wine/bin/wine64"
-terminal_dir: "~/Library/Application Support/net.metaquotes.wine.metatrader5/drive_c/Program Files/MetaTrader 5"
+wine_executable: "/path/to/wine64"
+terminal_dir: "/path/to/MetaTrader 5"
 ```

-## 4. Register MCP Server
+`setup.sh` auto-detects both.

 ## Troubleshooting

 **Agents connect then immediately disconnect**
 - MT5 version mismatch between `metatester64.exe` (from Mac) and the master. Use the exact same build number.
- Check `~/mt5agents/agents.log` for Wine errors.

 **Agents show as connected but don't receive work**
- MT5 sometimes requires optimization to be started before assigning work to new agents.
 - Start an optimization from the MT5 GUI first to "activate" remote agents, then cancel it and use MT5-Quant.

 **Performance is slower with remote agents**
- Network latency between Mac and Linux server. Results are sent over TCP after each pass.
- Local gigabit network: negligible. WiFi or WAN: significant overhead. Use wired connection.
-
-**Linux server runs out of memory**
- Each `metatester64.exe` instance uses ~200-400MB.
- 8 agents = ~2-3GB RAM. Size agent count accordingly.
