WHAT IT DOES

What strategy_backtest does on MetaTrader5 MCP Server

AI agents invoke strategy_backtest to trigger actions in MetaTrader5 MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why strategy_backtest is rated High

From the tool's definition 'Backtest simple indicator-driven trading strategies on MT5 candle history' — runs a simulation/execution process against historical data using trading strategy logic

RECOMMENDED RULE

The rule that runs strategy_backtest safely

strategy_backtest Rate-limited

strategy_backtest stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
