* Refactor cli.py into cli and utils modules Extract constants, enums, Click parameter types, and parse/export utility functions into a new mt5cli/utils.py module, keeping the typer app, commands, and collect-history SQLite helpers in cli.py. https://claude.ai/code/session_016JwSEhPyq6phXySktQ1FGU * Address review comments * Add programmatic SDK layer for read-only MT5 data collection. Expose Mt5CliClient and collect_history through the package API while keeping CLI commands as thin adapters over the SDK. Co-authored-by: Cursor <cursoragent@cursor.com> * Harden SDK connection lifecycle and scope internal helpers as private. Co-authored-by: Cursor <cursoragent@cursor.com> * Export build_config in the public API and bump version to 0.4.0. Co-authored-by: Cursor <cursoragent@cursor.com> * Remove duplicate scripts/ in favor of local-qa skill script.

# API Reference
|
|
|
|
This section contains the complete API documentation for mt5cli.
|
|
|
|
## Modules
|
|
|
|
The mt5cli package consists of the following modules:
|
|
|
|
### [CLI](cli.md)
|
|
|
|
Command-line interface module providing typer-based commands for exporting MetaTrader 5 data to CSV, JSON, Parquet, and SQLite3 formats.
|
|
|
|
### [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.
|
|
|
|
## 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
|
|
|
|
# Export EURUSD H1 rates to Parquet
|
|
mt5cli -o rates.parquet rates-from --symbol EURUSD --timeframe H1 \
|
|
--date-from 2024-01-01 --count 1000
|
|
|
|
# Export ticks to JSON
|
|
mt5cli -o ticks.json ticks-from --symbol EURUSD \
|
|
--date-from 2024-01-01 --count 500 --flags ALL
|
|
|
|
# Export to SQLite3 with custom table name
|
|
mt5cli -o data.db --table symbols symbols --group "*USD*"
|
|
```
|
|
|
|
## Python API
|
|
|
|
```python
|
|
from datetime import UTC, datetime
|
|
from pathlib import Path
|
|
|
|
from mt5cli import (
|
|
Mt5CliClient,
|
|
collect_history,
|
|
copy_rates_range,
|
|
detect_format,
|
|
export_dataframe,
|
|
)
|
|
|
|
# Fetch rates programmatically
|
|
rates = copy_rates_range(
|
|
"EURUSD",
|
|
timeframe="H1",
|
|
date_from="2024-01-01",
|
|
date_to="2024-02-01",
|
|
)
|
|
|
|
# Detect output format from file extension
|
|
fmt = detect_format(Path("output.parquet")) # Returns "parquet"
|
|
|
|
# Export a DataFrame
|
|
export_dataframe(rates, Path("output.csv"), "csv")
|
|
|
|
# Collect history into SQLite
|
|
collect_history(
|
|
Path("history.db"),
|
|
symbols=["EURUSD"],
|
|
date_from=datetime(2024, 1, 1, tzinfo=UTC),
|
|
date_to=datetime(2024, 2, 1, tzinfo=UTC),
|
|
)
|
|
```
