- Add run_rolling_backtest tool for N consecutive weekly backtests
- Add max_passes support for optimization to cap genetic passes
- Kill stale MT5/agent processes before optimization launch
- Auto-parse optimization results on status poll when process completes
- Fix XML namespace for SpreadsheetML parsing
- Change optimization model from 4 to 1 for better accuracy
- Persist completion results to job metadata
- CHANGELOG: inactivity_kill_secs default is disabled (None), not 120
- TROUBLESHOOTING: clarify inactivity_kill_secs is opt-in (must be
passed explicitly); correct "default 120" claim
- MCP_TOOLS: inactivity_kill_secs is disabled by default; add note
that Wine/macOS may not exit naturally even with ShutdownTerminal=1
- handlers/backtest.rs: remove stale comment claiming inactivity
watchdog is "intentionally skipped when shutdown=true" — replaced
with accurate description of the new 30s HTML-wait + kill behavior
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- fix: inactivity watchdog now waits 30s for HTML report then kills
terminal64.exe unconditionally — ShutdownTerminal=1 does not cause
MT5 to exit on Wine/macOS; relying on natural exit caused all runs
to fall back to journal extraction
- fix: tester agent log deduplication — each deal is written twice in
the log; use HashSet to skip already-seen deal numbers
- fix: position tracker for entry direction inference — infer "in"/"out"
from per-symbol signed lot accumulation instead of guessing
- fix: is_closed_trade() no longer gates on profit!=0.0 — journal deals
have profit=0.0 legitimately; the old gate hid all 140 deals from
list_deals
- fix: log file selection priority — prefer Agent-127.0.0.1 over
Agent-0.0.0.0 (startup-only log), tiebreak by file size
- feat: launch_backtest default shutdown=true; inactivity_kill_secs
default 120s exposed as tool parameter
- feat: report DB stores deals in SQLite; analytics resolve by
report_id / report_dir / latest
Verified: 1-month DPS21/XAUUSD.cent/M5 backtest produces full HTML
report with all metrics (win_rate=70%, profit_factor=0.77, sharpe=-3.61,
max_dd=6.93%) and all 17 analytics tools returning real data.

Add ini_safe() helper that strips CR/LF from user-supplied string params
before they are written into terminal.ini and backtest_config.ini.
Applies to: expert path, symbol, timeframe, set_file — any value that
could carry an embedded newline and inject extra INI directives.

database.rs:
- search_by_tags: replace string-interpolated LIKE with parameterized ?N bindings
- search_by_notes: replace format!() SQL with prepared statement + ?1/?2 params
- search_by_set_file: same — use ?1 for pattern and ?2 for limit
backtest.rs (extract_and_store / monitor_backtest_completion):
- extract_and_store now returns bool — callers only delete report file if true
- guard both success paths with conditional delete + warning on failure
- replace .parent().unwrap() panic with explicit match + error log + graceful return

On the first tool call of each session, a background task fires once
and fetches the latest release tag from the GitHub API (5 s timeout).
The result is cached in a static OnceLock for the lifetime of the
process — no repeated network calls.
check_update: returns cached result instantly, or fetches on demand
if the background task hasn't completed yet.
update: downloads the latest tarball for the current platform, extracts
the binary, and atomically replaces the running executable via a
temp-file rename. Requires MCP reconnect to activate new version.
Platform support: macos-aarch64, macos-x86_64, linux-x86_64.
Unsupported platforms return a build-from-source hint.
Tool count: 87 → 89. README and MCP_TOOLS.md updated.

- Add handle_notification() for notification messages (no id field)
- Use CARGO_PKG_VERSION for dynamic version in initialize response
- Skip serializing None fields in McpResponse and McpError
- Remove verified field from setup info
tracing_subscriber::fmt::init() defaults to stdout, contaminating the
MCP JSON-RPC stream and causing Claude Code and Windsurf to fail the
initialize handshake with "failed to reconnect".

Both handlers accepted a user-supplied output_path without boundary
validation, allowing MCP clients to write files to arbitrary filesystem
locations. A new safe_output_path() helper canonicalizes the parent
directory and asserts the resolved path stays within the allowed base
directory before any fs::write() call.
Also fixes pre-existing unused-import/dead-code warnings that blocked
the -D warnings release build.

High Priority Tools:
- check_symbol_data_status: validate symbol history data availability
- get_backtest_history: list all backtest results for EA/symbol
- compare_backtests: side-by-side comparison of multiple backtests
Medium Priority Tools:
- init_project: scaffold new MQL5 project with templates (scalper/swing/grid)
- validate_ea_syntax: pre-compile syntax checking
- check_mt5_status: check MT5 terminal readiness
Low Priority Tools:
- create_set_template: generate .set files from EA inputs
- export_report: export reports to CSV/JSON/Markdown
Other Changes:
- Consolidate config into src/models/config.rs, delete src/config.rs
- Add CurrentAccount with UTF-16LE parsing for common.ini
- Add BacktestPreflight struct for pre-flight checks
- Update backtest handler with active account context
- Update list_symbols to filter by active server
Total tools: 57
- Add auto_verify_result field to McpServer
- Run verify_setup automatically during initialize
- Include setup status in serverInfo response:
- verified: bool
- hint: string message
- Users immediately see if environment is ready
Changes to src/compile/mql_compiler.rs:
- Stage compilation to /tmp/mt5_compile_{ea}/ to avoid spaces in paths
(Wine /compile: chokes on spaces in paths like 'Application Support')
- Use bare /log flag - writes log adjacent to source instead of custom path
- Remove host_to_wine_path() conversion - use Unix paths directly
- Simplify MetaEditor invocation (no shell script on Linux)
- Clean up error handling logic
Fixes compilation failures when MT5 is installed in paths containing spaces.
MT5 binaries (MetaEditor64.exe, metatester64.exe, terminal64.exe) are all
GUI applications with no command-line data export capability.
Removed:
- export_ohlc - Cannot read proprietary .hst binary format
- export_ticks - Cannot read proprietary .ticks binary format
- list_available_data - Only scanned directories, didn't export
Total tools: 46 → 43
Alternative for data export:
1. Use MT5 History Center GUI → Export
2. Create MQL5 script using CopyRates()/CopyTicks() → FileWrite
3. Run the MQL5 script inside MT5 terminal
**New Tools:**
- export_ohlc: Export OHLC bar data from MT5 history to CSV/JSON
- export_ticks: Export tick data from MT5 tick database to CSV/JSON
- list_available_data: List available OHLC and tick data in MT5
**Implementation:**
- definitions/data.rs: Tool schemas for data export
- handlers/data.rs: Handlers that scan MT5 directories:
- history/*.hst files (OHLC)
- Tester/cache/* (cached data)
- Bases/* (tick data)
- Provides guidance on how to export since MT5 uses proprietary binary formats
- Includes MQL5 script template for programmatic export
**Note:** MT5 uses proprietary .hst and .ticks binary formats.
Direct export requires MQL5 script using CopyRates()/CopyTicks().

- Database registration integrated into backtest pipeline
**compile_ea Tool Improvements:**
- Support both 'expert' (EA name) and 'expert_path' (full path) parameters
- Auto-discovery: searches MT5 Experts dir and current directory for .mq5 files
- Better error messages when EA not found
- Added files_synced and warning_list to response
- Updated tool definition to reflect new parameters
**Pipeline Updates:**
- Backtest pipeline now registers results in database after completion
- Equity charts moved to OS temp dir with unique report ID
- HTML reports cleaned up after extraction
- Set file snapshots preserved for reproducibility
**Dependencies:**
- Added rusqlite for SQLite database support

- Ensures users always see actionable error info when compilation fails
- Handle protocolVersion from client initialize request params
- Negotiate compatible version (fallback to 2024-11-05 for 2025.x requests)
- Fix 'unsupported protocol version' error when client sends empty version
- Replace hello_world demo tool with production-ready healthcheck tool
- Auto-detect OS platform, architecture, and version (macOS/Linux)
- Validate configuration: config file, Wine/MT5 paths, directories
- Add detailed mode with Rust version, paths, and environment variables
- Update workflow documentation with healthcheck as example
- Port full Python MT5-Quant MCP server to Rust
- Implement all MCP tools: verify_setup, list_symbols, list_experts, run_backtest, compile_ea
