CCXT Margin Call Protection: Automated Fail-Safe for Crypto Futures

When using CCXT for multi-exchange algorithmic trading, order exceptions frequently leave positions open without an accompanying stop-loss order. If the exchange matching engine experiences partial outages, unprotected positions face liquidation.

1. Maintenance Margin Ratio (MMR) & Liquidation Distance

Liquidation occurs when Margin Ratio = Maintenance Margin / Margin Balance >= 100%. AegisQuant enforces a proactive threshold: if Margin Ratio reaches 40%, the autonomous daemon initiates a staged de-leveraging unwind.

Python: CCXT Missing Stop-Loss Detection & Auto-Healing

    if not active:

    open_orders = exchange.fapiPrivate_get_openalgoorders()
    has_stop = any(o.get('symbol') == active[0]['symbol'] and o.get('algoStatus') == 'NEW' for o in open_orders)
    
    if not has_stop:

        amt = abs(float(active[0]['positionAmt']))
        side = 'SELL' if float(active[0]['positionAmt']) > 0 else 'BUY'
