Overview \u00b6 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 , a pandas-based data handler for MetaTrader 5. Architecture \u00b6 pdmt5 \u2014 canonical MT5 client, DataFrame/trading primitives, and MT5 constant parsing ( TIMEFRAME_* , COPY_TICKS_* , order types). mt5cli \u2014 public MT5Client API, schema contracts, storage helpers, CLI commands, and SQLite history collection built on pdmt5. mt5api \u2014 sibling HTTP adapter for remote MT5 access; not a dependency of mt5cli. Features \u00b6 Multi-format export : CSV, JSON, Parquet, and SQLite3 output formats Auto-detection : Format detection from file extensions Comprehensive data access : Rates, ticks, account info, symbols, orders, positions, and trading history Flexible timeframes : Named timeframes (M1, H1, D1, etc.) and numeric values Connection management : Optional credentials, server, and timeout configuration SQLite rate loading : Load mt5cli-managed rate tables/views for offline workflows Installation \u00b6 pip install mt5cli Python API for downstream packages \u00b6 Import MT5Client for generic MT5 data access, schema normalization, and optional order primitives.

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 \u2014 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.

Bulk Collection \u00b6 Command Description collect-history Collect rates, ticks, history-orders, and history-deals for one or more symbols into a single SQLite database (optional cash-event/position views) mt5cli -o history.db collect-history \\ --symbol EURUSD --symbol GBPUSD \\ --date-from 2024 -01-01 --date-to 2024 -02-01 \\ --dataset rates --dataset history-deals \\ --timeframe M1 --flags ALL --if-exists append --with-views collect-history options: Option Default Description --symbol/-s required Symbol to collect (repeat for multiple). --date-from required Start date in ISO 8601. --date-to required End date in ISO 8601. --dataset all four Repeatable: rates , ticks , history-orders , history-deals . --timeframe M1 Rates timeframe; recorded in a timeframe column on the rates table. --flags ALL Tick copy flags forwarded to copy_ticks_range . --if-exists fail append , replace , or fail when a target table already exists. --with-views off Add cash_events and positions_reconstructed views (requires the history-deals dataset). History orders and deals are fetched per symbol and concatenated, so the symbol filter is applied consistently across all datasets. The cash_events view is derived from symbol-filtered history_deals , so account-level cash events with empty or non-matching symbols may be excluded. The positions_reconstructed view excludes positions with no closing deal, uses volume-weighted open/close prices, and reports reversal deals ( DEAL_ENTRY_INOUT ) via volume_reversal / reversal_count . See the History schema diagram for a sample ER layout of the resulting database.

It additionally maintains rate___ compatibility views when create_rate_views=True . Rate view resolution \u00b6 Downstream tools can resolve mt5cli-managed compatibility view names from an existing SQLite history database without creating files or guessing naming schemes: from pathlib import Path from mt5cli.history import resolve_rate_view_name , resolve_rate_view_names # Single symbol and granularity view = resolve_rate_view_name ( Path ( \"history.db\" ), \"EURUSD\" , \"M1\" ) # Batch resolution in row-major order views = resolve_rate_view_names ( Path ( \"history.db\" ), [ \"EURUSD\" , \"GBPUSD\" ], [ \"M1\" , \"H1\" ], ) Resolution rules: Returns rate___ when a symbol stores one timeframe. Returns rate____ when multiple timeframes are stored for the same symbol. When multiple naming candidates apply, prefers an existing managed rate_*__* view from the candidate list. Falls back to single-timeframe naming when the database path is missing or rates metadata is unavailable. Pass require_existing=True to raise ValueError instead of returning a best-guess name when the database or view is missing. Accepts either a SQLite path or an open sqlite3.Connection . Rate data loading \u00b6 The canonical normalized rate table is rates ; compatibility views are named with rate___ for single-timeframe symbols or rate____ 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: from pathlib import Path from mt5cli import ( load_rate_data , load_rate_series_by_granularity , load_rate_series_from_sqlite , resolve_rate_table_name , ) from mt5cli.history import resolve_rate_view_name view = resolve_rate_view_name ( Path ( \"history.db\" ), \"EURUSD\" , \"M1\" , require_existing = True ) rates = load_rate_data ( Path ( \"history.db\" ), view , count = 1000 ) same_rates = load_rate_series_from_sqlite ( Path ( \"history.db\" ), table = view , count = 1000 ) table = resolve_rate_table_name ( \"EURUSD\" , \"M1\" ) # \"rates\" series = load_rate_series_by_granularity ( Path ( \"history.db\" ), symbols = [ \"EURUSD\" , \"GBPUSD\" ], granularities = [ \"M1\" , \"H1\" ], count = 500 , ) count returns the latest rows while preserving chronological order. Missing tables/views and mismatched explicit_tables lengths raise ValueError with the requested database target in the message. The loader accepts close-based OHLC rate data or tick-like bid/ask data. It validates that time exists, parses timestamps with pandas, and returns a DataFrame indexed by ascending DatetimeIndex named time . Multi-series rate loading \u00b6 For loading many rate series at once, build neutral RateTarget pairs and load them from SQLite in one call. View names are resolved via the same compatibility-view rules, or you can pass explicit_tables to bypass resolution: from pathlib import Path from mt5cli import build_rate_targets , load_rate_series_from_sqlite targets = build_rate_targets ([ \"EURUSD\" , \"GBPUSD\" ], [ \"M1\" , \"H1\" ]) series = load_rate_series_from_sqlite ( Path ( \"history.db\" ), targets , count = 1000 ) frame = series [ \"EURUSD\" , 1 ] # keyed by (symbol, integer timeframe) build_rate_targets() returns RateTarget(symbol, timeframe) pairs in row-major order, normalizing timeframe names such as \"M1\" to their integer values; set allow_missing_symbol=True to address series solely by explicit_tables (targets carry symbol=None ). resolve_rate_tables() maps targets to table or view names and validates that any explicit_tables count matches the target count. Pass require_existing=True to raise ValueError instead of returning a best-guess name when the database or managed view is missing. When explicit_tables is provided, names are returned as-is and require_existing is ignored. load_rate_series_from_sqlite() returns a mapping keyed by (symbol, integer timeframe) . Unless explicit_tables is supplied, it requires existing managed rate_* compatibility views and raises ValueError when they are missing. Duplicate (symbol, timeframe) targets are rejected. load_rate_series_by_granularity() is a thin wrapper that builds the targets, loads the series, and rekeys the result by granularity name to avoid converting integer timeframes downstream: from mt5cli import load_rate_series_by_granularity series = load_rate_series_by_granularity ( \"history.db\" , [ \"EURUSD\" ], [ \"M1\" , \"H1\" ], count = 1000 ) frame = series [ \"EURUSD\" , \"M1\" ] # keyed by (symbol | None, granularity_name)","title":"History Collection (SQLite)"},{"location":"api/history/#history-collection-sqlite","text":"","title":"History Collection (SQLite)"},{"location":"api/history/#mt5cli.history","text":"SQLite storage helpers for the collect-history incremental data pipeline.","title":"history"},{"location":"api/history/#mt5cli.history.DEFAULT_HISTORY_TIMEFRAMES","text":"DEFAULT_HISTORY_TIMEFRAMES : tuple [ str , ... ] = ( TIMEFRAME_NAMES )","title":"DEFAULT_HISTORY_TIMEFRAMES"},{"location":"api/history/#mt5cli.history.SqliteConnOrPath","text":"SqliteConnOrPath = Connection | Path | str","title":"SqliteConnOrPath"},{"location":"api/history/#mt5cli.history.logger","text":"logger = getLogger ( __name__ )","title":"logger"},{"location":"api/history/#mt5cli.history.DedupScope","text":"DedupScope ( where : str , params : tuple [ object , ... ], required_columns : frozenset [ str ], ) Scoped deduplication predicate and the columns it references.

Wraps :func: update_history (or a custom update_backend ) with a minimum interval between successful updates, so a tight application loop can call :meth: update every iteration without re-fetching MT5 history more often than desired. Timing uses a monotonic clock, so it is unaffected by wall-clock changes.

Resolving credentials and ${ENV_VAR} placeholders \u00b6 resolve_account_spec() / resolve_account_specs() merge explicit override values over AccountSpec fields and expand ${ENV_VAR} placeholders, keeping secrets out of plan/config files.

Other AttributeError / TypeError values always propagate.

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. from mt5cli import create_trading_client , mt5_trading_session with mt5_trading_session ( path = r \"C:\\Program Files\\MetaTrader 5\\terminal64.exe\" , login = \"12345\" , password = \"secret\" , server = \"Broker-Demo\" , retry_count = 2 , ) as client : positions = client . positions_get_as_df ( symbol = \"EURUSD\" ) client = create_trading_client ( login = 12345 , server = \"Broker-Demo\" ) try : account = client . account_info_as_dict () finally : client . shutdown () 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 \u00b6 These helpers are strategy-agnostic and do not depend on signal detection, betting logic, or scheduling code in downstream applications. from mt5cli import ( calculate_positions_margin , calculate_spread_ratio , calculate_margin_and_volume , close_open_positions , detect_position_side , determine_order_limits , estimate_order_margin , fetch_latest_closed_rates_for_trading_client , get_account_snapshot , get_positions_frame , get_symbol_snapshot , get_tick_snapshot , normalize_order_volume , place_market_order , ) account = get_account_snapshot ( client ) symbol = get_symbol_snapshot ( client , \"EURUSD\" ) tick = get_tick_snapshot ( client , \"EURUSD\" ) positions = get_positions_frame ( client , \"EURUSD\" ) side = detect_position_side ( client , \"EURUSD\" ) spread_ratio = calculate_spread_ratio ( client , \"EURUSD\" ) volume = normalize_order_volume ( 0.15 , volume_min = symbol [ \"volume_min\" ], volume_max = symbol [ \"volume_max\" ], volume_step = symbol [ \"volume_step\" ], ) buy_margin = ( estimate_order_margin ( client , \"EURUSD\" , \"BUY\" , volume ) if volume > 0 else 0.0 ) open_margin = calculate_positions_margin ( client , symbols = [ \"EURUSD\" ]) closed_bars = fetch_latest_closed_rates_for_trading_client ( client , symbol = \"EURUSD\" , granularity = \"M1\" , count = 100 , ) sizing = calculate_margin_and_volume ( client , \"EURUSD\" , unit_margin_ratio = 0.5 , preserved_margin_ratio = 0.2 , ) limits = determine_order_limits ( client , \"EURUSD\" , side = \"long\" , stop_loss_limit_ratio = 0.01 , take_profit_limit_ratio = 0.02 , ) preview = place_market_order ( client , symbol = \"EURUSD\" , volume = sizing [ \"buy_volume\" ], order_side = \"BUY\" , sl = limits [ \"stop_loss\" ], tp = limits [ \"take_profit\" ], 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 dictionaries containing the request, response, status, retcode, and dry_run flag; dry_run=True never sends an order or mutates Market Watch visibility. ensure_symbol_selected() adds hidden symbols to Market Watch before live order placement and SL/TP updates. Failed, malformed, or unknown broker retcodes are fail-closed and returned as status=\"failed\" while keeping the normalized response for inspection.

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 dictionaries containing the request, response, status, retcode, and dry_run flag; dry_run=True never sends an order or mutates Market Watch visibility. ensure_symbol_selected() adds hidden symbols to Market Watch before live order placement and SL/TP updates.

Overview \u00b6 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 , a pandas-based data handler for MetaTrader 5. Architecture \u00b6 pdmt5 \u2014 canonical MT5 client, DataFrame/trading primitives, and MT5 constant parsing ( TIMEFRAME_* , COPY_TICKS_* , order types). mt5cli \u2014 public MT5Client API, schema contracts, storage helpers, CLI commands, and SQLite history collection built on pdmt5. mt5api \u2014 sibling HTTP adapter for remote MT5 access; not a dependency of mt5cli. Features \u00b6 Multi-format export : CSV, JSON, Parquet, and SQLite3 output formats Auto-detection : Format detection from file extensions Comprehensive data access : Rates, ticks, account info, symbols, orders, positions, and trading history Flexible timeframes : Named timeframes (M1, H1, D1, etc.) and numeric values Connection management : Optional credentials, server, and timeout configuration SQLite rate loading : Load mt5cli-managed rate tables/views for offline workflows Installation \u00b6 pip install mt5cli Python API for downstream packages \u00b6 Import MT5Client for generic MT5 data access, schema normalization, and optional order primitives. Mt5CliClient remains available as a backward-compatible alias. from datetime import UTC , datetime from pathlib import Path from mt5cli import ( DataKind , Dataset , MT5Client , build_config , collect_history , export_dataframe , load_rate_data , minimum_margins , mt5_session , normalize_dataframe , recent_ticks , resolve_rate_view_name , ) # Persistent session for multiple calls with mt5_session ( build_config ( login = 12345 , server = \"Broker-Demo\" )) as client : rates = client . copy_rates_range ( \"EURUSD\" , timeframe = \"H1\" , date_from = \"2024-01-01\" , date_to = \"2024-02-01\" , ) positions = client . positions () check = client . order_check ({ \"action\" : 1 , \"symbol\" : \"EURUSD\" , \"volume\" : 0.1 }) # Normalize MT5 frames to the public schema contract before storage closed_rates = normalize_dataframe ( rates , DataKind . rates , symbol = \"EURUSD\" , timeframe = \"H1\" ) export_dataframe ( closed_rates , Path ( \"rates.csv\" ), \"csv\" ) # Offline rate loading from mt5cli-managed SQLite history view = resolve_rate_view_name ( Path ( \"history.db\" ), \"EURUSD\" , \"M1\" , require_existing = True ) offline_rates = load_rate_data ( Path ( \"history.db\" ), view , count = 1000 ) # One-off helpers still work without instantiating a client ticks = recent_ticks ( \"EURUSD\" , seconds = 300 ) margins = minimum_margins ( \"EURUSD\" ) collect_history ( Path ( \"history.db\" ), symbols = [ \"EURUSD\" , \"GBPUSD\" ], date_from = datetime ( 2024 , 1 , 1 , tzinfo = UTC ), date_to = datetime ( 2024 , 2 , 1 , tzinfo = UTC ), datasets = { Dataset . rates , Dataset . history_deals }, ) 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 \u2014 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. Quick Start \u00b6 # Export account information to CSV mt5cli -o account.csv account-info # Export EURUSD M1 rates to Parquet mt5cli -o rates.parquet rates-from --symbol EURUSD --timeframe M1 \\ --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 symbols to SQLite3 with custom table name mt5cli -o data.db --table symbols symbols --group \"*USD*\" # Export with connection credentials mt5cli --login 12345 --password mypass --server MyBroker-Demo \\ -o positions.csv positions Commands \u00b6 Rates \u00b6 Command Description rates-from Export rates from a start date rates-from-pos Export rates from a start position latest-rates Export latest rates rates-range Export rates for a date range Ticks \u00b6 Command Description ticks-from Export ticks from a start date ticks-range Export ticks for a date range ticks-recent Export ticks from a trailing window Information \u00b6 Command Description account-info Export account information terminal-info Export terminal information version Export MetaTrader 5 version information last-error Export the last error information symbols Export symbol list symbol-info Export symbol details symbol-info-tick Export the last tick for a symbol minimum-margins Export minimum-volume margin summary market-book Export market depth (order book) Trading \u00b6 Command Description orders Export active orders positions Export open positions history-orders Export historical orders history-deals Export historical deals recent-history-deals Export historical deals from a trailing window mt5-summary Export terminal/account status summary order-check Check funds sufficiency for a trade request order-send Send a trade request to the trade server ( --yes required) Use order-check to validate a request payload before running order-send --yes . Bulk Collection \u00b6 Command Description collect-history Collect rates, ticks, history-orders, and history-deals for one or more symbols into a single SQLite database (optional cash-event/position views) mt5cli -o history.db collect-history \\ --symbol EURUSD --symbol GBPUSD \\ --date-from 2024 -01-01 --date-to 2024 -02-01 \\ --dataset rates --dataset history-deals \\ --timeframe M1 --flags ALL --if-exists append --with-views collect-history options: Option Default Description --symbol/-s required Symbol to collect (repeat for multiple). --date-from required Start date in ISO 8601. --date-to required End date in ISO 8601. --dataset all four Repeatable: rates , ticks , history-orders , history-deals . --timeframe M1 Rates timeframe; recorded in a timeframe column on the rates table. --flags ALL Tick copy flags forwarded to copy_ticks_range . --if-exists fail append , replace , or fail when a target table already exists. --with-views off Add cash_events and positions_reconstructed views (requires the history-deals dataset). History orders and deals are fetched per symbol and concatenated, so the symbol filter is applied consistently across all datasets. The cash_events view is derived from symbol-filtered history_deals , so account-level cash events with empty or non-matching symbols may be excluded. The positions_reconstructed view excludes positions with no closing deal, uses volume-weighted open/close prices, and reports reversal deals ( DEAL_ENTRY_INOUT ) via volume_reversal / reversal_count .

Each dataset becomes a table; column names and types mirror the pdmt5 DataFrame schema for that export, with two additions: symbol is prepended on every table. timeframe is prepended on rates so appended runs at different bar sizes stay distinguishable. SQLite does not declare foreign keys. Rows are linked logically by symbol , time windows, and (for deals) position_id / order . Duplicate rows are removed on append using dataset-specific keys (for example ticket on history tables, or (symbol, timeframe, time) on rates). Optional views are created when --with-views is set and the history-deals dataset was written. Entity-relationship diagram \u00b6 Sample layout for a full collection with --with-views : erDiagram rates { TEXT symbol \"dedup key\" INTEGER timeframe \"dedup key\" TEXT time \"dedup key\" REAL open REAL high REAL low REAL close INTEGER tick_volume INTEGER spread INTEGER real_volume } ticks { TEXT symbol \"dedup key\" TEXT time \"dedup key\" INTEGER time_msc \"dedup key (preferred)\" REAL bid REAL ask REAL last INTEGER volume INTEGER flags REAL volume_real } history_orders { INTEGER ticket \"dedup key\" TEXT symbol TEXT time INTEGER type INTEGER state REAL volume_initial REAL price_open REAL price_current INTEGER magic } history_deals { INTEGER ticket \"dedup key\" INTEGER order INTEGER position_id \"groups position view\" TEXT symbol TEXT time INTEGER type \"0/1 trade, else cash event\" INTEGER entry \"0 IN, 1 OUT, 2 INOUT, 3 OUT_BY\" REAL volume REAL price REAL profit REAL commission REAL swap REAL fee } cash_events { INTEGER ticket TEXT symbol TEXT time INTEGER type REAL profit } positions_reconstructed { INTEGER position_id TEXT symbol TEXT open_time TEXT close_time INTEGER direction REAL volume_open REAL volume_close REAL volume_reversal REAL open_price REAL close_price REAL total_profit INTEGER reversal_count INTEGER deals_count } rates ||--o{ history_deals : \"symbol (logical)\" ticks ||--o{ history_deals : \"symbol (logical)\" history_orders ||--o{ history_deals : \"order ~ ticket (logical)\" history_deals ||--|| cash_events : \"VIEW: type NOT IN (0,1)\" history_deals ||--o{ positions_reconstructed : \"VIEW: GROUP BY position_id\" Tables and views \u00b6 Object Kind Source Notes rates table copy_rates_range Indexed on (symbol, timeframe, time) when columns exist. ticks table copy_ticks_range Indexed on (symbol, time) when columns exist. history_orders table history_orders_get Fetched per --symbol , then concatenated. history_deals table history_deals_get Fetched per --symbol , then concatenated. Indexed on (position_id, symbol) when present. cash_events view history_deals Non-trade deal types (deposits, balance ops, etc.). Requires type column. positions_reconstructed view history_deals One row per closed position_id ; volume-weighted prices and reversal stats. Column sets can vary with terminal and pdmt5 version. Views are skipped with a warning when required columns are missing. Incremental collection \u00b6 The update_history SDK path uses the same base tables and optional cash_events / positions_reconstructed views. It additionally maintains rate___ compatibility views when create_rate_views=True . Rate view resolution \u00b6 Downstream tools can resolve mt5cli-managed compatibility view names from an existing SQLite history database without creating files or guessing naming schemes: from pathlib import Path from mt5cli.history import resolve_rate_view_name , resolve_rate_view_names # Single symbol and granularity view = resolve_rate_view_name ( Path ( \"history.db\" ), \"EURUSD\" , \"M1\" ) # Batch resolution in row-major order views = resolve_rate_view_names ( Path ( \"history.db\" ), [ \"EURUSD\" , \"GBPUSD\" ], [ \"M1\" , \"H1\" ], ) Resolution rules: Returns rate___ when a symbol stores one timeframe. Returns rate____ when multiple timeframes are stored for the same symbol. When multiple naming candidates apply, prefers an existing managed rate_*__* view from the candidate list. Falls back to single-timeframe naming when the database path is missing or rates metadata is unavailable. Pass require_existing=True to raise ValueError instead of returning a best-guess name when the database or view is missing. Accepts either a SQLite path or an open sqlite3.Connection . Rate data loading \u00b6 The canonical normalized rate table is rates ; compatibility views are named with rate___ for single-timeframe symbols or rate____ 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: from pathlib import Path from mt5cli import ( load_rate_data , load_rate_series_by_granularity , load_rate_series_from_sqlite , resolve_rate_table_name , ) from mt5cli.history import resolve_rate_view_name view = resolve_rate_view_name ( Path ( \"history.db\" ), \"EURUSD\" , \"M1\" , require_existing = True ) rates = load_rate_data ( Path ( \"history.db\" ), view , count = 1000 ) same_rates = load_rate_series_from_sqlite ( Path ( \"history.db\" ), table = view , count = 1000 ) table = resolve_rate_table_name ( \"EURUSD\" , \"M1\" ) # \"rates\" series = load_rate_series_by_granularity ( Path ( \"history.db\" ), symbols = [ \"EURUSD\" , \"GBPUSD\" ], granularities = [ \"M1\" , \"H1\" ], count = 500 , ) count returns the latest rows while preserving chronological order. Missing tables/views and mismatched explicit_tables lengths raise ValueError with the requested database target in the message. The loader accepts close-based OHLC rate data or tick-like bid/ask data. It validates that time exists, parses timestamps with pandas, and returns a DataFrame indexed by ascending DatetimeIndex named time . Multi-series rate loading \u00b6 For loading many rate series at once, build neutral RateTarget pairs and load them from SQLite in one call. View names are resolved via the same compatibility-view rules, or you can pass explicit_tables to bypass resolution: from pathlib import Path from mt5cli import build_rate_targets , load_rate_series_from_sqlite targets = build_rate_targets ([ \"EURUSD\" , \"GBPUSD\" ], [ \"M1\" , \"H1\" ]) series = load_rate_series_from_sqlite ( Path ( \"history.db\" ), targets , count = 1000 ) frame = series [ \"EURUSD\" , 1 ] # keyed by (symbol, integer timeframe) build_rate_targets() returns RateTarget(symbol, timeframe) pairs in row-major order, normalizing timeframe names such as \"M1\" to their integer values; set allow_missing_symbol=True to address series solely by explicit_tables (targets carry symbol=None ). resolve_rate_tables() maps targets to table or view names and validates that any explicit_tables count matches the target count. Pass require_existing=True to raise ValueError instead of returning a best-guess name when the database or managed view is missing. When explicit_tables is provided, names are returned as-is and require_existing is ignored. load_rate_series_from_sqlite() returns a mapping keyed by (symbol, integer timeframe) . Unless explicit_tables is supplied, it requires existing managed rate_* compatibility views and raises ValueError when they are missing. Duplicate (symbol, timeframe) targets are rejected. load_rate_series_by_granularity() is a thin wrapper that builds the targets, loads the series, and rekeys the result by granularity name to avoid converting integer timeframes downstream: from mt5cli import load_rate_series_by_granularity series = load_rate_series_by_granularity ( \"history.db\" , [ \"EURUSD\" ], [ \"M1\" , \"H1\" ], count = 1000 ) frame = series [ \"EURUSD\" , \"M1\" ] # keyed by (symbol | None, granularity_name)","title":"History Collection (SQLite)"},{"location":"api/history/#history-collection-sqlite","text":"","title":"History Collection (SQLite)"},{"location":"api/history/#mt5cli.history","text":"SQLite storage helpers for the collect-history incremental data pipeline.","title":"history"},{"location":"api/history/#mt5cli.history.DEFAULT_HISTORY_TIMEFRAMES","text":"DEFAULT_HISTORY_TIMEFRAMES : tuple [ str , ... ] = ( TIMEFRAME_NAMES )","title":"DEFAULT_HISTORY_TIMEFRAMES"},{"location":"api/history/#mt5cli.history.SqliteConnOrPath","text":"SqliteConnOrPath = Connection | Path | str","title":"SqliteConnOrPath"},{"location":"api/history/#mt5cli.history.logger","text":"logger = getLogger ( __name__ )","title":"logger"},{"location":"api/history/#mt5cli.history.DedupScope","text":"DedupScope ( where : str , params : tuple [ object , ... ], required_columns : frozenset [ str ], ) Scoped deduplication predicate and the columns it references.

None of them depend on a particular trading application.

Multi-account helpers fetch count + 1 bars, drop that row with drop_forming_rate_bar() , and validate each series is non-empty. Returned frames are ordered oldest-to-newest and may contain fewer than count rows only when MT5 returns fewer closed bars. from mt5cli import ( AccountSpec , collect_latest_closed_rates_by_granularity , fetch_latest_closed_rates , ) closed = fetch_latest_closed_rates ( client , symbol = \"EURUSD\" , granularity = \"M1\" , count = 500 , ) rates = collect_latest_closed_rates_by_granularity ( [ AccountSpec ( symbols = [ \"EURUSD\" ], login = 12345 )], [ \"M1\" , \"H1\" ], count = 500 , retry_count = 3 , ) closed_m1 = rates [ \"EURUSD\" , \"M1\" ] Use collect_latest_closed_rates_by_granularity() when callers prefer keys such as (\"EURUSD\", \"M1\") instead of integer timeframes.

This opt-in covers substitute_env_placeholders() , resolve_account_spec() , resolve_account_specs() , and build_config() . Note: build_config cannot expand login because that parameter is int | None ; use resolve_account_spec for a string login placeholder.

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. from mt5cli import create_trading_client , mt5_trading_session with mt5_trading_session ( path = r \"C:\\Program Files\\MetaTrader 5\\terminal64.exe\" , login = \"12345\" , password = \"secret\" , server = \"Broker-Demo\" , retry_count = 2 , ) as client : positions = client . positions_get_as_df ( symbol = \"EURUSD\" ) client = create_trading_client ( login = 12345 , server = \"Broker-Demo\" ) try : account = client . account_info_as_dict () finally : client . shutdown () 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 \u00b6 These helpers are strategy-agnostic and do not depend on signal detection, betting logic, or scheduling code in downstream applications. from mt5cli import ( calculate_positions_margin , calculate_spread_ratio , calculate_margin_and_volume , close_open_positions , detect_position_side , determine_order_limits , estimate_order_margin , fetch_latest_closed_rates_for_trading_client , fetch_latest_closed_rates_indexed , get_account_snapshot , get_positions_frame , get_symbol_snapshot , get_tick_snapshot , normalize_order_volume , place_market_order , ) account = get_account_snapshot ( client ) symbol = get_symbol_snapshot ( client , \"EURUSD\" ) tick = get_tick_snapshot ( client , \"EURUSD\" ) positions = get_positions_frame ( client , \"EURUSD\" ) side = detect_position_side ( client , \"EURUSD\" ) spread_ratio = calculate_spread_ratio ( client , \"EURUSD\" ) volume = normalize_order_volume ( 0.15 , volume_min = symbol [ \"volume_min\" ], volume_max = symbol [ \"volume_max\" ], volume_step = symbol [ \"volume_step\" ], ) buy_margin = ( estimate_order_margin ( client , \"EURUSD\" , \"BUY\" , volume ) if volume > 0 else 0.0 ) open_margin = calculate_positions_margin ( client , symbols = [ \"EURUSD\" ]) closed_bars = fetch_latest_closed_rates_for_trading_client ( client , symbol = \"EURUSD\" , granularity = \"M1\" , count = 100 , ) # Or fetch with a UTC DatetimeIndex instead of a \"time\" column: indexed_bars = fetch_latest_closed_rates_indexed ( client , symbol = \"EURUSD\" , granularity = \"M1\" , count = 100 , ) # indexed_bars.index is a UTC-aware DatetimeIndex named \"time\" sizing = calculate_margin_and_volume ( client , \"EURUSD\" , unit_margin_ratio = 0.5 , preserved_margin_ratio = 0.2 , ) limits = determine_order_limits ( client , \"EURUSD\" , side = \"long\" , stop_loss_limit_ratio = 0.01 , take_profit_limit_ratio = 0.02 , ) preview = place_market_order ( client , symbol = \"EURUSD\" , volume = sizing [ \"buy_volume\" ], order_side = \"BUY\" , sl = limits [ \"stop_loss\" ], tp = limits [ \"take_profit\" ], 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 dictionaries containing the request, response, status, retcode, and dry_run flag; dry_run=True never sends an order or mutates Market Watch visibility. ensure_symbol_selected() adds hidden symbols to Market Watch before live order placement and SL/TP updates. Failed, malformed, or unknown broker retcodes are fail-closed and returned as status=\"failed\" while keeping the normalized response for inspection.

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 dictionaries containing the request, response, status, retcode, and dry_run flag; dry_run=True never sends an order or mutates Market Watch visibility. ensure_symbol_selected() adds hidden symbols to Market Watch before live order placement and SL/TP updates.
