## Why BinancePortfolioMarginCmChangeMarginType is rated Medium

This tool modifies account configuration for futures trading by switching margin type between ISOLATED and CROSSED modes. This is a reversible write operation (you can switch back), but it has high severity because changing margin type on active futures positions can affect liquidation risk, margin requirements, and overall portfolio risk exposure.

From the tool's own definition: "Change margin type (ISOLATED/CROSSED) for a COIN-M Futures symbol in Portfolio Margin mode"
