Schedule Cancel Example (Dead Man's Switch)

Schedule automatic cancellation of all orders after a delay.

all your orders are cancelled. Useful as a safety mechanism.

NOTE: Requires $1M trading volume on your account to use this feature.

Requirements:
    pip install hyperliquid-sdk

Usage:
    export PRIVATE_KEY="0x..."
    python schedule_cancel.py
