WHAT IT DOES

What patterns_detect does on MetaTrader5 MCP Server

AI agents call patterns_detect 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.

RISK

Why patterns_detect is rated Low

Given the server context (market data and trading functionality) and sibling tools that are all data-retrieval/analysis oriented, 'patterns_detect' most likely detects technical chart patterns from market data — a read/analysis operation with no side effects. However, the empty description lowers confidence.

From the tool's definition Tool name 'patterns_detect' on a MetaTrader5 server with sibling tools focused on market data analysis (candles, ticks, indicators, correlation). Description is empty.
