According to @CrypNuevo, a rapid flash crash drove top-20 altcoins down 50%-80% in a single candle, citing failures across liquidity, market makers, and exchanges, with many stop losses not executing due to the speed of the move, source: @CrypNuevo on X (Oct 10, 2025). In fast, gapping markets, stop orders can slip or go unfilled when price jumps through the trigger and available order book depth, heightening liquidation risk for leveraged traders, source: Binance Support (order types and slippage education) and CME Group education (stop orders and price gaps). Traders facing these conditions should reduce leverage and size, use limit or stop-limit over pure stop-market where appropriate, and monitor order book depth and venue stability to manage execution risk during cascades, source: Binance Support (risk warnings and order execution mechanics) and CME Group education (order handling in volatile markets).
