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.

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
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().
**Granular Analytics Tools (8 new tools):**
- analyze_monthly_pnl - Monthly profit/loss breakdown
- analyze_drawdown_events - Drawdown events from balance curve
- analyze_top_losses - Top N worst losses with grid depth
- analyze_loss_sequences - Consecutive loss streaks analysis
- analyze_position_pairs - Entry/exit position pairs
- analyze_direction_bias - Long vs Short performance stats
- analyze_streaks - Win/loss streaks with dates
- analyze_concurrent_peak - Peak concurrent open positions
**Updated analyze_report:**
- Now supports selective analytics via 'analytics' array parameter
- Runs all analytics by default (backward compatible)
- Optional top_losses_limit parameter
- Returns list of analytics that were run
**Changes:**
- analytics/analyze.rs: Made all analysis methods public
- tools/definitions.rs: Added 8 new tool definitions + updated analyze_report schema
- tools/handlers/mod.rs: Added dispatch for new tools
- tools/handlers/analysis.rs: Added helper load_report_data() + 8 granular handlers + selective analyze_report logic
