# trade_execution_quality Measure fill slippage, latency, partial fills, fees, and post-fill markouts. Agent View of the PolicyLayer registry record for `trade_execution_quality`. HTML page: https://policylayer.com/tools/emerzon-mt-data-mcp/trade-execution-quality ## Facts - Tool: `trade_execution_quality` - Server: MetaTrader5 MCP Server (`emerzon/mt-data-mcp`) — https://policylayer.com/tools/emerzon-mt-data-mcp.md - Homepage: https://github.com/emerzon/mt-data-mcp - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "trade_execution_quality", "arguments": {} } } ``` ## Why trade_execution_quality is rated Low Despite being on a trading platform, this tool performs analysis and measurement of existing trade data. It reads metrics about past fills but does not initiate, modify, or cancel orders, nor does it move money or execute transactions. The most severe realistic misuse (an agent analyzing execution quality to decide future actions) remains informational. From the tool's own definition: "Tool measures and analyzes trade execution metrics (fill slippage, latency, partial fills, fees, markouts) — it retrieves and queries post-execution data for analysis rather than executing trades or moving funds." ## Use case AI agents call trade_execution_quality to retrieve information from MetaTrader5 MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches MetaTrader5 MCP Server: ```json { "version": "1", "default": "deny", "tools": { "trade_execution_quality": {} } } ``` ## Other tools on MetaTrader5 MCP Server (81) - `forecast_models_cleanup` — Destructive — https://policylayer.com/tools/emerzon-mt-data-mcp/forecast-models-cleanup.md - `forecast_models_delete` — Destructive — https://policylayer.com/tools/emerzon-mt-data-mcp/forecast-models-delete.md - `forecast_task_cancel` — Destructive — https://policylayer.com/tools/emerzon-mt-data-mcp/forecast-task-cancel.md - `forecast_task_cancel_all` — Destructive — https://policylayer.com/tools/emerzon-mt-data-mcp/forecast-task-cancel-all.md - `forecast_backtest_run` — Execute — https://policylayer.com/tools/emerzon-mt-data-mcp/forecast-backtest-run.md - `forecast_generate` — Execute — https://policylayer.com/tools/emerzon-mt-data-mcp/forecast-generate.md - `forecast_task_wait` — Execute — https://policylayer.com/tools/emerzon-mt-data-mcp/forecast-task-wait.md - `forecast_train` — Execute — https://policylayer.com/tools/emerzon-mt-data-mcp/forecast-train.md - `forecast_tune_genetic` — Execute — https://policylayer.com/tools/emerzon-mt-data-mcp/forecast-tune-genetic.md - `forecast_tune_optuna` — Execute — https://policylayer.com/tools/emerzon-mt-data-mcp/forecast-tune-optuna.md - `options_heston_calibrate` — Execute — https://policylayer.com/tools/emerzon-mt-data-mcp/options-heston-calibrate.md - `strategy_backtest` — Execute — https://policylayer.com/tools/emerzon-mt-data-mcp/strategy-backtest.md - `strategy_validate` — Execute — https://policylayer.com/tools/emerzon-mt-data-mcp/strategy-validate.md - `wait_event` — Execute — https://policylayer.com/tools/emerzon-mt-data-mcp/wait-event.md - `forecast_barrier_optimize` — Financial — https://policylayer.com/tools/emerzon-mt-data-mcp/forecast-barrier-optimize.md - `options_barrier_price` — Financial — https://policylayer.com/tools/emerzon-mt-data-mcp/options-barrier-price.md - `trade_close` — Financial — https://policylayer.com/tools/emerzon-mt-data-mcp/trade-close.md - `trade_modify` — Financial — https://policylayer.com/tools/emerzon-mt-data-mcp/trade-modify.md - `trade_place` — Financial — https://policylayer.com/tools/emerzon-mt-data-mcp/trade-place.md - `trade_risk_analyze` — Financial — https://policylayer.com/tools/emerzon-mt-data-mcp/trade-risk-analyze.md - `trade_var_cvar_calculate` — Financial — https://policylayer.com/tools/emerzon-mt-data-mcp/trade-var-cvar-calculate.md - `causal_discover_signals` — Other — https://policylayer.com/tools/emerzon-mt-data-mcp/causal-discover-signals.md - `forecast_barrier_prob` — Other — https://policylayer.com/tools/emerzon-mt-data-mcp/forecast-barrier-prob.md - `forecast_optimize_hints` — Other — https://policylayer.com/tools/emerzon-mt-data-mcp/forecast-optimize-hints.md - `labels_triple_barrier` — Other — https://policylayer.com/tools/emerzon-mt-data-mcp/labels-triple-barrier.md - `report_generate` — Other — https://policylayer.com/tools/emerzon-mt-data-mcp/report-generate.md - `temporal_analyze` — Other — https://policylayer.com/tools/emerzon-mt-data-mcp/temporal-analyze.md - `trade_session_context` — Other — https://policylayer.com/tools/emerzon-mt-data-mcp/trade-session-context.md - `asset_performance` — Read — https://policylayer.com/tools/emerzon-mt-data-mcp/asset-performance.md - `cointegration_test` — Read — https://policylayer.com/tools/emerzon-mt-data-mcp/cointegration-test.md - …and 51 more: https://policylayer.com/tools/emerzon-mt-data-mcp.md ## For agents This record is a snapshot.
