The Vibe: Telling the exchange, “only buy or sell at this exact price or better”—like setting a price tag on a garage sale item and waiting for someone to agree, instead of selling to the first person who shows up.
The Details: A limit order is a trade instruction on an exchange (CEX or DEX) where you specify the exact price you want to buy or sell at (or better). For a buy limit order, you set a maximum price you’re willing to pay—the order only fills if the market price drops to or below your limit. For a sell limit order, you set a minimum price you’ll accept—the order fills only if the market rises to or above it. Unlike market orders (which execute immediately at the current price), limit orders wait in the order book until matched. They help control price and avoid bad fills from volatility or slippage, but they might never execute if the market doesn’t reach your price.
Pro Tip: Use limit orders for better control—set buy limits below current price during dips, or sell limits above during pumps. Check the order book to place realistic limits near support/resistance. On DEXs, limit orders may use aggregators or off-chain matching for efficiency. Always double-check your price and amount before confirming.
