Example use cases
Automated risk management during volatility
“I'm getting nervous about my ETH perpetual position with this market spike. Add another 200 USDC margin to bring my leverage down and reduce my liquidation risk.”
Rebalance portfolio leverage after gains
“My SOL futures trade hit a nice profit. Lower my leverage by bumping the margin up to 300 USDC so I can protect my gains without closing the position.”
Adjust margin for intraday trading strategy
“I want to take a bigger directional bet on BTC for the next few hours. Cut my margin down so I'm running at 25x leverage instead of 15x.”
