RISK

Why place_stop_loss is rated Critical

This tool places an on-chain financial order on a perpetual DEX. Stop-loss orders are financial instruments that automatically trigger trades/position closures when price thresholds are hit, directly committing financial obligations and affecting real assets on-chain. Misuse could result in unintended liquidation of positions or financial losses.
