DEX-side price is read from GeckoTerminal's pool price fields. net_spread_pct only subtracts an assumed flat gas cost - it does NOT subtract the DEX pool's own swap fee (see pool_fee_pct), CEX trading fees, CEX deposit/withdrawal availability, or slippage beyond trade_size_usd. A spread that looks profitable before the pool fee may not be after it - re-verify with live quotes before executing a real trade.",
