answers 402
DEX vs CEX arbitrage spread — the price difference between DEX and CEX with the fee-adjusted NET spread and execution direction, not two raw prices. Compares the most liquid DEX pair (DexScreener) to CEX spot (Binance/Bybit), subtracts taker+swap fees, and flags any profitable arbitrage opportunity. For arbitrage agents.
