# PR Feedback Triage
|
||||
|
||||
Triage pull request review feedback, decide what action each thread needs, make focused fixes when allowed, and report or resolve only what is actually handled.
|
||||
|
||||
## When to Use
|
||||
|
||||
- A PR has review comments, requested changes, unresolved review threads, or bot review findings.
|
||||
- The user asks to address, respond to, or resolve PR feedback.
|
||||
- The user provides a PR URL/number, a branch with an associated PR, or copied comments.
|
||||
|
||||
Do not use this skill for a first-pass code review with no existing feedback; use a code review skill instead.
|
||||
|
||||
## Inputs
|
||||
|
||||
- Pull request URL or number, or a current branch that has an associated pull request.
|
||||
- Repository checkout or platform access sufficient to inspect the PR diff and review feedback.
|
||||
- Optional reviewer priorities from the user, such as "only address blocking comments" or "do not reply on the PR platform".
|
||||
- Optional operating mode flags: `dry_run`, `no_push`, and `no_reply`.
|
||||
|
||||
If no PR or review comments are identifiable, ask for the target PR or the copied comments before proceeding.
|
||||
|
||||
## Modes
|
||||
|
||||
- `dry_run`: inspect review feedback and report the triage only. Do not edit files, run write-mode formatters, commit, push, post replies, or resolve review threads.
|
||||
- `no_push`: local edits and verification are allowed, but do not push commits or otherwise update the remote branch. Report the local diff or local commits that still need to be pushed. Do not resolve threads whose resolution depends on unpushed local edits.
|
||||
- `no_reply`: do not post replies, submit reviews, or resolve review threads. Provide suggested replies and resolution actions in the final report instead.
|
||||
|
||||
When a mode disables an action, skip that destructive or externally visible action even if normal workflow text would otherwise allow it.
|
||||
|
||||
## Preflight
|
||||
|
||||
1. Identify the current branch and target PR.
|
||||
2. Check tracked local changes with `git diff --name-only` and `git diff --cached --name-only`. Ignore untracked files unless the review feedback explicitly concerns them.
|
||||
3. Check unpushed commits before relying on remote review feedback.
|
||||
4. If tracked local changes or unpushed commits exist, warn that existing PR comments may not cover the latest local state. In `normal` mode, push only when the user request or repository workflow allows it; otherwise continue with a clearly reported limitation.
|
||||
|
||||
## Feedback Collection
|
||||
|
||||
Gather the complete feedback set before editing:
|
||||
|
||||
- Fetch unresolved review threads, requested-change reviews, PR-level summary comments, and copied comments.
|
||||
- Use platform-native APIs/CLI when available. Paginate results; do not inspect only the first page of threads or comments.
|
||||
- For bot reviewers that post both summary comments and inline comments, collect both. Summary comments often contain severity, rationale, and fix instructions; inline comments contain the exact file and line context.
|
||||
- Preserve every thread/comment identifier needed to reply or resolve later.
|
||||
- Compare each comment with the current diff and file contents because review lines can become outdated.
|
||||
|
||||
## Deduplication and Ordering
|
||||
|
||||
Build one triage record per distinct finding:
|
||||
|
||||
- Prefer exact review-thread identity when available.
|
||||
- For duplicate bot findings appearing in both summary and inline comments, merge by exact issue title first, then by file path plus line range as a fallback.
|
||||
- Prefer inline comments for location and current code context.
|
||||
- Prefer summary comments for severity, category, rationale, and detailed agent prompts.
|
||||
- Preserve the reviewer’s exact issue title and original wording where practical. Do not rename findings in a way that would make replies hard to map back to comments.
|
||||
- Preserve the reviewer’s original ordering unless the user asks for priority reordering. Many review bots already order findings by severity.
|
||||
|
||||
Each triage record should track: original title, reviewer, source IDs, location, current applicability, severity/priority if available, disposition, planned action, verification, reply text if any, resolution decision, platform action attempted, and final platform state.
|
||||
|
||||
## Resolution Policy
|
||||
|
||||
In normal mode, `Resolve conversation` is the default action for any review thread that has been fully handled. A thread is handled when the requested change is implemented and verified, the current code already satisfies the comment, the comment is outdated and no longer applies, or a deliberate deferral/won't-fix response has been posted with a clear reason.
|
||||
|
||||
Keep a thread open only when it still needs reviewer, maintainer, or product input, the fix is local-only and not pushed, verification is missing for a material change, or the user explicitly requested `dry_run`, `no_push`, or `no_reply` behavior that prevents resolution.
|
||||
|
||||
When resolving a thread, add a concise reply first only if it provides useful context, such as what changed, why no code change was needed, why a finding was intentionally deferred, or why the original comment is now outdated. Do not add noisy replies for self-evident fixes unless project norms require them.
|
||||
|
||||
## Platform Action Contract
|
||||
|
||||
Do not treat triage as complete until every collected source ID reaches an explicit terminal state:
|
||||
|
||||
- `resolved`: a platform resolve action succeeded, or a re-check shows the thread is already resolved.
|
||||
- `replied_left_open`: a reply or question was posted and the thread is intentionally left unresolved.
|
||||
- `not_resolvable`: the source is a PR-level summary comment or copied comment that has no platform-level resolve action; reply or post a PR summary when useful.
|
||||
- `skipped_by_mode`: `dry_run`, `no_push`, or `no_reply` prevented the external action.
|
||||
- `failed_action`: a reply or resolve action was attempted and failed; include the attempted action and failure in the final summary.
|
||||
|
||||
In normal mode, build and execute a platform action queue after fixes are verified and pushed when needed:
|
||||
|
||||
- `reply_then_resolve`: use for handled threads where the reviewer needs context before resolution.
|
||||
- `resolve_only`: use for self-evident fixes and already-addressed or outdated threads where an extra reply would add noise.
|
||||
- `reply_leave_open`: use only for clarification requests, blocked work, or intentionally open follow-ups.
|
||||
- `reply_only`: use for PR-level comments or summaries that cannot be resolved as review threads.
|
||||
|
||||
For duplicate findings, execute the terminal action for every source thread ID, not only the primary triage record. If one finding is represented by three unresolved inline threads, all three must be resolved or explicitly left open.
|
||||
|
||||
## GitHub Action Guidance
|
||||
|
||||
Prefer platform-native APIs or `gh` commands that expose review-thread resolution state. For GitHub inline review threads, use the thread node ID and the GraphQL `resolveReviewThread` mutation rather than assuming that a reply resolves the conversation.
|
||||
|
||||
A reliable pattern is:
|
||||
|
||||
1. Re-fetch review threads and comments immediately before acting.
|
||||
2. Reply to the thread when the action queue says a reply is needed.
|
||||
3. Resolve the review thread by node ID when the terminal state should be `resolved`.
|
||||
4. Re-fetch unresolved review threads after the action queue completes.
|
||||
5. Retry any expected-to-be-resolved thread that is still unresolved once; if it still remains unresolved, mark it `failed_action` instead of claiming completion.
|
||||
|
||||
Example GraphQL mutation shape:
|
||||
|
||||
```graphql
|
||||
mutation($threadId: ID!) {
|
||||
resolveReviewThread(input: {threadId: $threadId}) {
|
||||
thread {
|
||||
id
|
||||
isResolved
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
A posted reply alone is sufficient only for `reply_leave_open`, `reply_only`, or `not_resolvable` sources. For handled inline review threads, reply and resolve are separate actions.

|
||||
```
|
||||
|
||||
## Compact Workflow
|
||||
|
||||
1. **Collect all relevant feedback**
|
||||
- Identify the PR and gather unresolved review threads, requested-change reviews, PR-level summaries, inline comments, and copied comments.
|
||||
- Paginate all platform calls and keep comment/thread IDs for later replies and resolution.
|
||||
- For bot reviews, collect both summary and inline comments, then merge duplicates rather than fixing the same finding twice.
|
||||
|
||||
2. **Classify each triage record**
|
||||
- **Fix**: Valid requested change; make the smallest focused edit when not in `dry_run`.
|
||||
- **Answer**: No code change needed; prepare a concise explanation.
|
||||
- **Clarify**: Ambiguous, conflicting, or missing context; reply with the question and leave unresolved.
|
||||
- **Already addressed**: Current code already satisfies it; prepare evidence.
|
||||
- **Outdated**: Commented code or issue no longer exists; prepare evidence.
|
||||
- **Defer / Won't fix**: Valid concern intentionally not changed now; document a specific reason.
|
||||
|
||||
3. **Act according to the classification and mode**
|
||||
- Keep edits scoped to the review feedback.
|
||||
- Follow reviewer-provided fix instructions literally when they are still applicable; deviate only when the current code proves the instruction is stale or unsafe.
|
||||
- In `dry_run`, stop at triage, proposed fixes, suggested replies, and verification plan.
|
||||
- In `no_push`, local edits are allowed, but do not push or resolve threads whose fix is only local. Reply or resolve non-code, already-addressed, or outdated threads only when the action does not depend on unpushed work and `no_reply` is not set.
|
||||
- In `no_reply`, do not post replies or resolve threads; report suggested replies/actions instead.
|
||||
- In normal mode, commit and push changed code when appropriate, then execute the platform action queue for every collected source ID.
|
||||
|
||||
4. **Verify before claiming completion**
|
||||
- For fixes, run appropriate checks or explain why they could not run.
|
||||
- Re-inspect the updated diff and comment context to confirm the concern is resolved.
|
||||
- Re-fetch review threads after reply/resolve actions and confirm all expected-to-be-resolved thread IDs are resolved.
|
||||
- Do not mark a thread resolved if it still needs reviewer, maintainer, or product input.
|
||||
- If a resolve or reply operation fails, retry once when safe; then report `failed_action` with the affected source ID and reason.
|
||||
|
||||
5. **Finish**
|
||||
- Normal mode: commit/push changes when appropriate, post useful replies or a summary, resolve all handled threads by default, and reconcile the final unresolved set.
|
||||
- Safe modes: report the local state and the exact replies/resolution actions a human could take.
|
||||
|
||||
## Reply Guidance
|
||||
|
||||
- Keep inline replies short and tied to the original title or concern.
|
||||
- For fixed findings, mention the concrete change or commit if useful.
|
||||
- For already-addressed or outdated findings, cite the current code path or behavior that makes the finding no longer applicable.
|
||||
- For deferred or won't-fix findings, provide the reason and any follow-up issue or owner if known.
|
||||
- If a reply or resolve operation fails, continue with the remaining threads and report the failure in the final summary.
|
||||
|
||||
## Final Summary Checklist
|
||||
|
||||
- Mode used: `normal`, `dry_run`, `no_push`, or `no_reply`
|
||||
- Counts by disposition: fixed, answered, clarified/left open, already addressed, outdated, deferred/won't-fix
|
||||
- Counts by platform terminal state: resolved, replied-left-open, not-resolvable, skipped-by-mode, failed-action
|
||||
- Threads resolved, intentionally left open, already resolved, or resolution actions skipped by mode
|
||||
- Any expected-to-be-resolved thread that remained unresolved after retry
|
||||
- Verification run or planned
|
||||
- Commits pushed, local diff/commits, or "none"
|
||||
- Remaining open items and who needs to respond

# Repository Guidelines
|
||||
|
||||
## Commands
|
||||
## Project Structure & Module Organization
|
||||
|
||||
### Development Setup
|
||||
`mt5cli/` contains the package source. Important modules include `cli.py` for the Typer command-line app, `client.py` and `sdk.py` for public MT5 client/session APIs, `history.py` for SQLite history collection, `storage.py` and `converters.py` for export behavior, and `schemas.py` for normalized dataset contracts. `tests/` holds pytest coverage for CLI behavior, SDK contracts, trading helpers, history, and utilities. `docs/` and `mkdocs.yml` define the MkDocs site and API reference. `skills/mt5cli/SKILL.md` documents the mt5cli agent skill.
|
||||
|
||||
```bash
|
||||
uv sync
|
||||
```
|
||||
## Build, Test, and Development Commands
|
||||
|
||||
### Code Quality and Documentation
|
||||
- `uv sync` installs runtime and development dependencies from `pyproject.toml` and `uv.lock`.
|
||||
- `uv run mt5cli --help` runs the local CLI entry point.
|
||||
- `uv run ruff format .` formats Python files.
|
||||
- `uv run ruff check --fix .` lints and applies safe fixes.
|
||||
- `uv run pyright .` runs strict type checking.
|
||||
- `uv run pytest` runs doctests, branch coverage, and the test suite.
|
||||
- `uv run mkdocs serve` previews documentation locally; `uv run mkdocs build` validates the docs build.
|
||||
|
||||
**Important**: Run these before committing or creating a PR.
|
||||
Use `.agents/skills/local-qa/SKILL.md` for pre-handoff QA. It runs `.agents/skills/local-qa/scripts/qa.sh`, which formats, lints, type-checks, tests, formats Markdown, and checks GitHub workflows.
|
||||
|
||||
1. **format, lint, and test**: Use `local-qa` skill.
|
||||
2. **Documentation build** (if any public API changes): `uv run mkdocs build`
|
||||
## Coding Style & Naming Conventions
|
||||
|
||||
## Architecture
|
||||
Target Python `>=3.11,<3.14`. Use Ruff’s configured 88-character line length and Google-style docstrings. Pyright is strict, so prefer explicit public type annotations and narrow exception handling. Keep module, function, and variable names in `snake_case`; classes and enums use `PascalCase`. Preserve the package’s small, typed helper style rather than adding broad abstractions.
|
||||
|
||||
### Key Dependencies
|
||||
## Design Principles
|
||||
|
||||
- **pdmt5**: Pandas-based data handler for MetaTrader 5 (core library)
|
||||
- **typer**: CLI framework for building command-line interfaces
|
||||
- **click**: Parameter type customization for CLI options
|
||||
- **pandas**: Core data manipulation and analysis
|
||||
Apply KISS, DRY, and YAGNI when changing code. Prefer the simplest implementation that satisfies the current CLI/API contract. Remove duplication when shared behavior is already proven by at least two concrete call sites, but avoid generic helpers for speculative reuse. Do not add configuration flags, extension hooks, or alternate backends until a real repository use case requires them.
|
||||
|
||||
### Package Structure
|
||||
## Testing Guidelines
|
||||
|
||||
- `mt5cli/`: Main package directory
|
||||
- `__init__.py`: Package initialization and exports (`detect_format`, `export_dataframe`)
|
||||
- `cli.py`: CLI application with typer-based commands for data export
|
||||
- `utils.py`: Constants, enums, parameter types, parsers, and export utilities
|
||||
- `__main__.py`: Entry point for `python -m mt5cli`
|
||||
- `tests/`: Comprehensive test suite (pytest-based)
|
||||
- `test_cli.py`: Tests for CLI commands and collect-history behavior
|
||||
- `test_utils.py`: Tests for utility constants, parameter types, parsers, and export functions
|
||||
- `docs/`: MkDocs documentation with API reference
|
||||
- `docs/index.md`: Main documentation
|
||||
- `docs/api/`: Auto-generated API documentation for all modules
|
||||
- Modern Python packaging with `pyproject.toml` and uv dependency management
|
||||
|
||||
### Quality Standards
|
||||
|
||||
- Type hints required (pyright strict mode)
|
||||
- Comprehensive linting with 35+ rule categories (ruff)
|
||||
- Test coverage tracking with 100% (pytest-cov)
|
||||
- Parametrized tests for input/result matrices using `pytest.mark.parametrize` (pytest)
|
||||
- Test doubles (mocks, stubs) using `pytest_mock` for external dependencies (pytest-mock)
|
||||
- Pydantic models for data validation and configuration
|
||||
|
||||
### Documentation workflow
|
||||
|
||||
1. Add Google-style docstrings to functions/classes
|
||||
2. Local preview: `uv run mkdocs serve`
|
||||
3. Build: `uv run mkdocs build`
|
||||
4. Deploy: `uv run mkdocs gh-deploy`
|
||||
Tests use pytest, pytest-mock, doctests, and pytest-cov. Test files should match `tests/test_*.py`, classes `Test*`, and functions `test_*`. Coverage is configured with `fail_under = 100`, so add focused tests for every behavior change. Mock MT5/pdmt5 boundaries; do not require a live MetaTrader terminal in unit tests.
|
||||
|
||||
## Commit & Pull Request Guidelines
|
||||
|
||||
- Run QA checks using `local-qa` skill before committing or creating a PR.
|
||||
- Branch names use appropriate prefixes on creation (e.g., `feature/...`, `bugfix/...`, `refactor/...`, `docs/...`, `chore/...`).
|
||||
- When instructed to create a PR, create it as a draft with appropriate labels by default.
|
||||
Recent history uses concise imperative commits, sometimes with conventional prefixes such as `feat:` or `chore:` and PR numbers appended by GitHub. Keep commits scoped to one logical change. Pull requests should describe behavior changes, note tests run, link related issues, and call out MT5/live-trading risk where relevant.
|
||||
|
||||
## Code Design Principles
|
||||
## Security & Configuration Tips
|
||||
|
||||
Always prefer the simplest design that works.
|
||||
|
||||
- **KISS**: Choose straightforward solutions and avoid unnecessary abstraction.
|
||||
- **DRY**: Remove duplication when it improves clarity and maintainability.
|
||||
- **YAGNI**: Do not add features, hooks, or flexibility until they are needed.
|
||||
- **SOLID/Clean Code**: Apply these as tools, only when they keep the design simpler and easier to change.
|
||||
|
||||
## Development Methodology
|
||||
|
||||
Keep delivery incremental, test-backed, and easy to review.
|
||||
|
||||
- Make small, safe, reversible changes.
|
||||
- Prefer `Red -> Green -> Refactor`.
|
||||
- Do not mix feature work and refactoring in the same commit.
|
||||
- Refactor when it improves clarity or removes real duplication (Rule of Three).
|
||||
- Keep tests fast, focused, and self-validating.
|
||||
Never commit account credentials, broker passwords, exported private data, or local `.venv` contents. Treat `order_send` and CLI `order-send --yes` as live execution paths; gate examples and tests so they cannot place real trades accidentally.

Schema contracts live in `mt5cli.schemas` (`DataKind`, `validate_schema`, `normalize_dataframe`). Storage helpers are re-exported from `mt5cli.storage` and the package root.
|
||||
|
||||
`MT5Client.order_send()` is a live execution primitive: it can place real trades on the connected account. mt5cli does not implement strategy logic, signal generation, backtesting, or optimization — downstream applications must gate live execution explicitly.
|
||||
|
||||
### Trading lifecycle and state helpers
|
||||
|
||||
Trading applications can depend on `mt5cli` imports only; terminal path,
|
||||
credentials, server, and timeout are forwarded to `pdmt5.Mt5Config`, numeric
|
||||
login strings are coerced to integers, and empty login strings are treated as
|
||||
unset.
|
||||
|
||||
```python
|
||||
from mt5cli import (
|
||||
calculate_spread_ratio,

### Migration note for downstream trading apps
|
||||
|
||||
Replace local MT5 lifecycle and trading helper code with mt5cli imports:
|
||||
|
||||
```python
|
||||
# Before (local application helpers)
|
||||
# with local_mt5_trading_session(config) as client:

|
||||
# After (mt5cli shared layer)
|

from pdmt5 import Mt5Config
|
||||
from mt5cli import (
|
||||
calculate_margin_and_volume,
|
||||
detect_position_side,
|
||||
determine_order_limits,
|
||||
mt5_trading_session,
|
||||
)
|
||||
|
||||
with mt5_trading_session(
|
||||
Mt5Config(path=terminal_path, login=login), retry_count=2
|
||||
) as client:
|
||||
side = detect_position_side(client, symbol)
|
||||
sizing = calculate_margin_and_volume(
|
||||
client, symbol, unit_margin_ratio=0.5, preserved_margin_ratio=0.2
|
||||
)
|
||||
if side is not None:
|
||||
limits = determine_order_limits(
|
||||
client,

|
||||
stop_loss_limit_ratio=0.01,
|
||||
take_profit_limit_ratio=0.02,
|
||||
)
|
||||
```
|
||||
|
||||
Throttled history updates use a separate read-only session:
|
||||
|
||||
```python
|
||||
from pdmt5 import Mt5Config, Mt5DataClient
|
||||
|
||||
from mt5cli import ThrottledHistoryUpdater
|
||||
|
||||
updater = ThrottledHistoryUpdater(
|
||||
output="history.db", interval_seconds=60, suppress_errors=True
|
||||
)
|
||||
client = Mt5DataClient(config=Mt5Config(login=login))
|
||||
client.initialize_and_login_mt5()
|
||||
try:
|
||||
updater.update(client, ["EURUSD"])
|
||||
finally:
|
||||
client.shutdown()
|
||||
```
|
||||
|
||||
Read-only collectors can keep using `mt5_session()` and `MT5Client` (or the `Mt5CliClient` alias) without changes.

### Rate data loading
|
||||
|
||||
Use `load_rate_data()` to load a table or view from a SQLite path, or
|
||||
`load_rate_data_from_connection()` when you already have a connection:
|
||||
The canonical normalized rate table is `rates`; compatibility views are named
|
||||
with `rate_<symbol>__<timeframe>` for single-timeframe symbols or
|
||||
`rate_<symbol>__<granularity>_<timeframe>` when a symbol has multiple stored
|
||||
timeframes. `resolve_rate_table_name()` returns `rates`, while
|
||||
`resolve_rate_view_name()` returns the per-symbol compatibility view name.
|
||||
|
||||
Use `load_rate_data()` or `load_rate_series_from_sqlite(..., table=...)` to load
|
||||
a single table or view from a SQLite path. Use
|
||||
`load_rate_series_by_granularity()` to load multiple instrument/granularity
|
||||
targets without hard-coding view names:
|
||||
|
||||
```python
|
||||
from pathlib import Path
|

|
||||
from mt5cli import load_rate_data
|
||||
from mt5cli import (

||||
load_rate_data,

||||
resolve_rate_table_name,
|

||||
from mt5cli.history import resolve_rate_view_name

`count` returns the latest rows while preserving chronological order. Missing

# API Reference
|
||||
|
||||
This section contains the complete API documentation for mt5cli.
|
||||
This section documents the mt5cli public Python API and CLI modules.
|
||||
|
||||
## Modules
|
||||
Start with the [Public API Contract](public-contract.md) for the stable
|
||||
downstream SDK surface, CLI boundary, internal modules, and out-of-scope strategy
|
||||
responsibilities.
|
||||
|
||||
The mt5cli package consists of the following modules:
|
||||
## Public API layers
|
||||
|
||||
### [CLI](cli.md)
|
||||
| Module | Purpose |
|
||||
| ----------------------------------------- | ------------------------------------------------------------------------- |
|
||||
| [Public API Contract](public-contract.md) | Stable downstream SDK exports, CLI boundary, and out-of-scope items |
|
||||
| [Client](client.md) | `MT5Client` session abstraction for data access and order primitives |
|
||||
| [Schemas](schemas.md) | Canonical DataFrame contracts and normalization helpers |
|
||||
| [Storage](storage.md) | CSV/JSON/Parquet/SQLite export and history collection helpers |
|
||||
| [Converters](converters.md) | Symbol, timeframe, timezone, and date-range utilities |
|
||||
| [Exceptions](exceptions.md) | Stable mt5cli exception types and MT5 error normalization |
|
||||
| [SDK](sdk.md) | Module-level fetch helpers, multi-account collectors, incremental history |
|
||||
| [Trading](trading.md) | Trading-capable sessions and operational helpers |
|
||||
| [History Collection (SQLite)](history.md) | SQLite schema, incremental writes, dedup, and rate views |
|
||||
| [CLI](cli.md) | Typer commands that delegate to the Python API |
|
||||
| [Utils](utils.md) | Parsing helpers and Click parameter types |
|
||||
|
||||
Command-line interface module providing typer-based commands for exporting MetaTrader 5 data to CSV, JSON, Parquet, and SQLite3 formats.
|
||||
## Architecture overview
|
||||
|
||||
### [Utils](utils.md)
|
||||
|
||||
Utility module providing constants, enums, Click parameter types, and helper functions for parsing and exporting data.
|
||||
|
||||
### [SDK](sdk.md)
|
||||
|
||||
Programmatic SDK for read-only MetaTrader 5 data collection. Returns pandas DataFrames and provides `collect_history` for SQLite bulk collection.
|
||||
|
||||
### [History Collection (SQLite)](history.md)
|
||||
|
||||
SQLite storage helpers for the `collect-history` command schema, incremental updates, deduplication, indexes, and optional views.
|
||||
|
||||
## Architecture Overview
|
||||
|
||||
The package follows a simple architecture built on top of pdmt5:
|
||||
|
||||
1. **CLI Layer** (`cli.py`): Typer application with subcommands that delegate to the SDK and export results.
|
||||
2. **SDK Layer** (`sdk.py`): Read-only data access functions, `Mt5CliClient`, and `collect_history` orchestration.
|
||||
3. **Utils Layer** (`utils.py`): Constants, enums, custom Click parameter types, parsing helpers, and format detection/export utilities.
|
||||
4. **Data Layer** (via `pdmt5`): Uses `Mt5DataClient` and `Mt5Config` from the pdmt5 package for all MetaTrader 5 data access.
|
||||
|
||||
## Usage Guidelines
|
||||
|
||||
All modules follow these conventions:
|
||||
|
||||
- **Type Safety**: All functions include comprehensive type hints
|
||||
- **Error Handling**: User-friendly error messages via typer
|
||||
- **Documentation**: Google-style docstrings with examples
|
||||
- **Validation**: Custom Click parameter types for input validation
|
||||
|
||||
## Quick Start
|
||||
|
||||
```bash
|
||||
# Export account information to CSV
|
||||
mt5cli -o account.csv account-info
|
||||

## Python API
|
||||
Downstream packages should depend on the package root exports documented in the
|
||||
[Public API Contract](public-contract.md) (`MT5Client`,
|
||||
`DataKind`, `normalize_dataframe`, `collect_history`, `load_rate_data`,
|
||||
`resolve_rate_view_name`, etc.) rather than private modules.
|
||||
|
||||
`MT5Client.order_send()` is a live execution primitive that can place real trades. mt5cli exposes minimal execution helpers only; strategy logic, signals, backtests, and optimization remain out of scope and must be implemented downstream with explicit execution gating.

```text
|
||||
downstream app -> mt5cli -> pdmt5 -> MetaTrader 5
|
||||
```
|
||||
|
||||
Downstream packages should import from the package root (`from mt5cli import
|
||||
...`) and treat the symbols listed below as the stable SDK contract. CLI
|
||||
commands mirror the same behavior but are not importable Python APIs.
|
||||
|
||||
## Stable downstream SDK API
|
||||
|
||||
These names are exported from `mt5cli` and covered by the contract in
|
||||
`mt5cli.STABLE_SDK_EXPORTS` (defined in `mt5cli.contract`). Prefer `MT5Client` over the legacy `Mt5CliClient`
|
||||
alias for new code.
|
||||
|
||||
### Session lifecycle and configuration
|
||||
|
||||
| Symbol | Role |
|
||||
| ----------------------------------------------- | ---------------------------------------------------------------- |
|
||||
| `MT5Client`, `Mt5CliClient` | Read-only data client with optional `order_check` / `order_send` |
|
||||
| `build_config` | Build `pdmt5.Mt5Config` from connection fields |
|
||||
| `mt5_session` | Context manager: initialize, login, yield client, shutdown |
|
||||
| `create_trading_client`, `mt5_trading_session` | Trading-capable `pdmt5.Mt5TradingClient` lifecycle |
|
||||
| `AccountSpec` | Generic account group: symbols plus optional credentials |
|
||||
| `resolve_account_spec`, `resolve_account_specs` | Merge overrides and expand `${ENV_VAR}` placeholders |
|
||||
| `substitute_env_placeholders` | Replace `${NAME}` substrings from the environment |
|
||||
|
||||
Credential resolution is generic: any environment variable name may appear inside
|
||||
`${...}`. mt5cli does not hard-code application-specific keys such as
|
||||
`mt5_login` or `mt5_exe`.
|
||||
|
||||
### Read-only MT5 data access
|
||||
|
||||
Module-level helpers open a transient connection per call. Prefer `mt5_session`
|
||||
or `MT5Client` when making many requests in one process.
|
||||
|
||||
| Area | Symbols |
|
||||
| -------------------- | ---------------------------------------------------------------------------------------------------- |
|
||||
| Rates | `copy_rates_from`, `copy_rates_from_pos`, `copy_rates_range`, `latest_rates`, `collect_latest_rates` |
|
||||
| Ticks | `copy_ticks_from`, `copy_ticks_range`, `recent_ticks` |
|
||||
| Account / terminal | `account_info`, `terminal_info`, `mt5_version`, `last_error`, `mt5_summary`, `mt5_summary_as_df` |
|
||||
| Symbols / market | `symbols`, `symbol_info`, `symbol_info_tick`, `market_book`, `minimum_margins` |
|
||||
| Trading state (read) | `orders`, `positions`, `history_orders`, `history_deals`, `recent_history_deals` |
|
||||
|
||||
Use `mt5_version` for MetaTrader 5 terminal version data. The name `version` at
|
||||
the package root refers to `importlib.metadata.version` (package metadata), not
|
||||
the MT5 SDK helper.
|
||||
|
||||
### Closed-bar rate helpers
|
||||
|
||||
MetaTrader 5 returns the still-forming bar as the last row when
|
||||
`start_pos=0`. Use these helpers instead of reimplementing bar trimming or
|
||||
timestamp normalization in downstream apps.
|
||||
|
||||
| Symbol | Role |
|
||||
| ------------------------------------------------ | ------------------------------------------------------------ |
|
||||
| `drop_forming_rate_bar` | Remove the last row from chronologically ordered rate data |
|
||||
| `fetch_latest_closed_rates` | Single connected client: fetch `count + 1`, drop forming bar |
|
||||
| `fetch_latest_closed_rates_for_trading_client` | Closed bars from an active `Mt5TradingClient` session |
|
||||
| `collect_latest_closed_rates_for_accounts` | Multi-account closed bars with optional retry wrapper |
|
||||
| `collect_latest_closed_rates_by_granularity` | Same data keyed by `(symbol, granularity_name)` |
|
||||
| `collect_latest_rates_for_accounts` | Latest bars including the forming bar when `start_pos=0` |
|
||||
| `collect_latest_rates_for_accounts_with_retries` | Bounded exponential backoff for transient MT5 errors |
|
||||
|
||||
### SQLite history collection and rate loading
|
||||
|
||||
| Symbol | Role |
|
||||
| ----------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------- |
|
||||
| `collect_history` | One-shot date-range export into SQLite |
|
||||
| `update_history`, `update_history_with_config` | Incremental append from `MAX(time)` cursors |
|
||||
| `ThrottledHistoryUpdater` | Minimum interval between successful incremental updates; optional `update_backend` injection |
|
||||
| `resolve_history_datasets`, `resolve_history_timeframes`, `resolve_history_tick_flags` | History pipeline configuration |
|
||||
| `build_rate_view_name`, `resolve_rate_table_name`, `resolve_rate_view_name`, `resolve_rate_view_names`, `resolve_rate_tables` | Map symbols/timeframes to mt5cli-managed table or view names |
|
||||
| `RateTarget`, `build_rate_targets` | Neutral `(symbol, timeframe)` series descriptors |
|
||||
| `load_rate_data`, `load_rate_data_from_connection` | Load one table/view into a time-indexed DataFrame |
|
||||
| `load_rate_series_from_sqlite`, `load_rate_series_by_granularity` | Load one or many series; fail clearly when managed views are missing |
|
||||
|
||||
Pass `require_existing=True` to rate view resolution helpers when downstream
|
||||
code must fail instead of receiving a best-guess view name. Multi-series loaders
|
||||
require existing managed `rate_*__*` views unless `explicit_tables` is supplied.
|
||||
|
||||
See [History Collection (SQLite)](history.md) for schema, view naming, and ER
|
||||
diagrams.
|
||||
|
||||
### Trading and sizing primitives (generic)
|
||||
|
||||
These helpers implement broker-facing calculations only. They do not encode
|
||||
strategy entries, exits, Kelly sizing, or signal logic.
|
||||
|
||||
| Symbol | Role |
|
||||
| -------------------------------------------------------------------------------------------------- | --------------------------------------------- |
|
||||
| `get_account_snapshot`, `get_symbol_snapshot`, `get_tick_snapshot`, `get_positions_frame` | Normalized account/symbol/tick/position views |
|
||||
| `detect_position_side` | Net long / short / flat from open positions |
|
||||
| `calculate_spread_ratio` | Relative bid-ask spread |
|
||||
| `calculate_margin_and_volume`, `calculate_volume_by_margin`, `calculate_new_position_margin_ratio` | Margin budget and volume sizing |
|
||||
| `normalize_order_volume`, `estimate_order_margin`, `calculate_positions_margin` | Broker volume normalization and margin totals |
|
||||
| `determine_order_limits` | SL/TP price levels from ratios |
|
||||
| `ensure_symbol_selected` | Select/verify Market Watch visibility |
|
||||
| `place_market_order`, `close_open_positions`, `update_sltp_for_open_positions` | Order execution helpers (`dry_run` supported) |
|
||||
| `MarginVolume`, `OrderLimits`, `OrderExecutionResult` | Typed return contracts for order helpers |
|
||||
| `OrderSide`, `OrderFillingMode`, `OrderTimeMode`, `PositionSide`, `ExecutionStatus` | Typed enums for order helpers |
|
||||
|
||||
`MT5Client.order_send()` and CLI `order-send --yes` are live execution paths.
|
||||
|
||||
Order helpers validate broker stop-level distance in `determine_order_limits()` and
|
||||
raise `Mt5TradingError` when computed SL/TP prices are too close to the entry
|
||||
quote. Validation uses `trade_stops_level * point` from the current quote and
|
||||
symbol metadata as a pre-check only; it does not guarantee live order acceptance
|
||||
after price movement and does not inspect `trade_freeze_level`. Live
|
||||
`place_market_order()` and SL/TP updates call
|
||||
`ensure_symbol_selected()` so hidden symbols are added to Market Watch before
|
||||
sending requests. Failed, malformed, or unknown broker retcodes are fail-closed
|
||||
and returned as `status="failed"` with normalized `request` / `response` details;
|
||||
`dry_run=True` never calls `ensure_symbol_selected()` or `order_send()`.
|
||||
|
||||
### Errors and MT5 type re-exports
|
||||
|
||||
| Symbol | Role |
|
||||
| ------------------------------------------------------------------------------------ | ----------------------------------------------- |
|
||||
| `Mt5CliError`, `Mt5ConnectionError`, `Mt5OperationError`, `Mt5SchemaError` | Stable mt5cli exception types |
|
||||
| `normalize_mt5_exception`, `call_with_normalized_errors`, `is_recoverable_mt5_error` | Error normalization and retry classification |
|
||||
| `Mt5Config`, `Mt5RuntimeError`, `Mt5TradingClient`, `Mt5TradingError` | Re-exported pdmt5 types for adapter convenience |
|
||||
|
||||
### Additional public exports (secondary)
|
||||
|
||||
The package root also exports schema, storage, and parsing helpers (for example
|
||||
`DataKind`, `Dataset`, `normalize_dataframe`, `export_dataframe`,
|
||||
`parse_timeframe`, `TIMEFRAME_MAP`). These are public but oriented toward export
|
||||
pipelines and advanced integration. Prefer the stable symbols above for core
|
||||
infrastructure.
|
||||
|
||||
## CLI commands
|
||||
|
||||
The Typer application in `mt5cli.cli` exposes file-export commands documented in
|
||||
[CLI Module](cli.md) and the project README. CLI commands:
|
||||
|
||||
- Require `-o/--output` and write CSV, JSON, Parquet, or SQLite.
|
||||
- Accept global MT5 connection options (`--login`, `--password`, `--server`,
|
||||
`--path`, `--timeout`).
|
||||
- Delegate to the same Python APIs described here; they are not duplicated
|
||||
business logic.
|
||||
|
||||
`order-send` requires `--yes` before placing live trades.
|
||||
|
||||
## Internal helpers (not stable)
|
||||
|
||||
Do not import these for downstream contracts; they may change without a semver
|
||||
notice:
|
||||
|
||||
| Module | Examples |
|
||||
| ------------------------ | ------------------------------------------------------------------------- |
|
||||
| `mt5cli.sdk` | `connected_client`, `_run_with_client`, private coercion helpers |
|
||||
| `mt5cli.history` | `write_*_dataset`, `deduplicate_history_tables`, `parse_sqlite_timestamp` |
|
||||
| `mt5cli.retry` | `retry_with_backoff` |
|
||||
| `mt5cli.cli` | Typer command handlers and Click parameter types |
|
||||
| Leading-underscore names | Any `_`-prefixed function or method |
|
||||
|
||||
Use the package-root stable exports instead of reaching into submodule
|
||||
internals.
|
||||
|
||||
## Explicitly out of scope
|
||||
|
||||
mt5cli must **not** implement downstream strategy or research responsibilities.
|
||||
The following belong in consuming applications, not in mt5cli:
|
||||
|
||||
- Signal detection (for example AR-GARCH or other model-specific triggers)
|
||||
- Backtesting, walk-forward analysis, or parameter optimization
|
||||
- Strategy-specific risk policy, position sizing systems, or Kelly fractions
|
||||
- Entry/exit decision logic or YAML strategy semantics
|
||||
- Application-specific credential schema keys wired into mt5cli internals
|
||||
|
||||
mt5cli provides connection lifecycle, normalized data access, SQLite history
|
||||
machinery, closed-bar helpers, generic margin/volume/spread/SL/TP utilities, and
|
||||
optional order primitives so downstream apps can focus on strategy code behind
|
||||
their own adapter layer.
|
||||
|
||||
## Contract verification
|
||||
|
||||
`tests/test_contracts.py` asserts that every name in `STABLE_SDK_EXPORTS` is
|
||||
importable from `mt5cli`, documents key closed-bar, rate-view, SQLite loading,
|
||||
account-resolution, and trading-session behaviors, and keeps the contract set
|
||||
aligned with `__all__`.

## Trading-capable MT5 sessions
|
||||
|
||||
`create_trading_client()` and `mt5_trading_session()` complement the read-only
|
||||
`mt5_session()` helper in `sdk.py`. They return or yield an initialized
|
||||
`pdmt5.Mt5TradingClient`, use `Mt5Config.path` to launch the terminal when
|
||||
configured, and `mt5_trading_session()` always calls `shutdown()` on exit.
|
||||
|
||||
```python
|
||||
from mt5cli import create_trading_client, mt5_trading_session
|
||||
|
||||
with mt5_trading_session(
|

|
||||
|
||||
`login` accepts `int`, numeric `str`, or an empty string; empty strings are
|
||||
treated as unset. `path`, `password`, `server`, and `timeout` are forwarded to
|
||||
`pdmt5.Mt5Config`, and omitted `timeout` values keep the lower-level default.
|
||||
The read-only `Mt5CliClient` / `mt5_session()` API is unchanged.
|
||||
|
||||
## State and order helpers
|
||||
|
||||
These helpers are strategy-agnostic and do not depend on signal detection,
|
||||
betting logic, or scheduling code in downstream applications.

||||

|
||||
dry_run=True,

|
||||
closed = close_open_positions(client, symbols="EURUSD", dry_run=True)
|
||||
```
|
||||
|
||||
`detect_position_side()` returns `long` for buy-only exposure, `short` for
|
||||
sell-only exposure, and `None` for no positions or mixed long/short exposure.
|
||||
`calculate_spread_ratio()` uses `(ask - bid) / ((ask + bid) / 2)` and raises
|
||||
`Mt5TradingError` when bid or ask is missing or non-positive.
|
||||
`normalize_order_volume()` returns `0.0` for invalid constraints or
|
||||
sub-minimum requests; check the result before calling `estimate_order_margin()`,
|
||||
which requires a positive finite volume. `calculate_positions_margin()` silently
|
||||
skips rows with missing symbols, non-positive volumes, non-finite volumes, or
|
||||
unsupported position types, but propagates `Mt5TradingError` from `estimate_order_margin()` when a valid row
|
||||
encounters invalid tick data or margin results from the broker.
|
||||
|
||||
SL/TP ratios for `determine_order_limits()` must satisfy `0 <= ratio < 1`; `0`
|
||||
omits that level. SL/TP prices are rounded with symbol `digits` metadata when
|
||||
available. `determine_order_limits()` pre-validates computed SL/TP prices against
|
||||
available `trade_stops_level * point` metadata when present; violations raise
|
||||
`Mt5TradingError`. This is a planning helper only: it does not guarantee broker
|
||||
acceptance because live validation can still depend on price movement, bid/ask
|
||||
side, freeze levels, and server-side rules, and it does not validate
|
||||
`trade_freeze_level`. When symbol metadata cannot be loaded, protective prices
|
||||
still round with `digits=8` and stop-level validation is skipped.
|
||||
`unit_margin_ratio` and `preserved_margin_ratio` for `calculate_margin_and_volume()`
|
||||
accept `0 <= ratio <= 1`; `unit_margin_ratio=0` requests one minimum valid unit
|
||||
when the post-reserve margin can afford it. Negative `margin_free` is clamped to
|
||||
`0.0` before sizing. Execution helpers return normalized `OrderExecutionResult`

# mt5cli
|
||||
|
||||
Command-line tool for MetaTrader 5 data export.
|
||||
Generic MT5 data and execution infrastructure for Python applications.
|
||||
|
||||
## Overview
|
||||
|
||||
mt5cli is a CLI application that exports MetaTrader 5 trading data to multiple file formats. It is built on top of [pdmt5](https://github.com/dceoy/pdmt5), a pandas-based data handler for MetaTrader 5.
|
||||
mt5cli provides a stable `MT5Client` Python API, standardized dataset schemas, storage helpers, and a CLI for exporting MetaTrader 5 data. It is built on top of [pdmt5](https://github.com/dceoy/pdmt5), a pandas-based data handler for MetaTrader 5.
|
||||
|
||||
## Architecture
|
||||
|
||||
- **pdmt5** — canonical MT5 client, DataFrame/trading primitives, and MT5 constant parsing (`TIMEFRAME_*`, `COPY_TICKS_*`, order types).
|
||||
- **mt5cli** — public `MT5Client` API, schema contracts, storage helpers, CLI commands, and SQLite history collection built on pdmt5.
|
||||
- **mt5api** — sibling HTTP adapter for remote MT5 access; not a dependency of mt5cli.

## Programmatic usage / SDK usage
|
||||
## Python API for downstream packages
|
||||
|
||||
mt5cli can be used as a small Python SDK for read-only MetaTrader 5 data collection. SDK functions return pandas DataFrames without writing files. Use `export_dataframe` or `export_dataframe_to_sqlite` when you need to persist results.
|
||||
Import `MT5Client` for generic MT5 data access, schema normalization, and optional order primitives. `Mt5CliClient` remains available as a backward-compatible alias.

|
||||
)
|
||||
```
|
||||
|
||||
Timeframes, tick flags, and ISO 8601 date strings are accepted wherever noted in the SDK API.
|
||||
Schema contracts live in `mt5cli.schemas` (`DataKind`, `validate_schema`, `normalize_dataframe`). Storage helpers are re-exported from `mt5cli.storage` and the package root.
|
||||
|
||||
`Mt5CliClient.mt5_summary()` returns the SDK structured form as plain nested Python values. Use `Mt5CliClient.mt5_summary_as_df()` when you need a one-row DataFrame for export. The `mt5-summary` CLI command uses this tabular form, so nested terminal/account fields are JSON-encoded strings that are safe for CSV, JSON, Parquet, and SQLite output.
|
||||
`MT5Client.order_send()` is a live execution primitive: it can place real trades on the connected account. mt5cli does not implement strategy logic, signal generation, backtesting, or optimization — downstream applications must gate live execution explicitly (the CLI requires `--yes` for `order-send`).
|
||||
|
||||
`MT5Client.mt5_summary()` returns structured nested Python values. Use `MT5Client.mt5_summary_as_df()` when you need a one-row DataFrame for export.
