A limit order is an instruction to buy or sell a cryptocurrency at a specific price or better rather than accepting whatever the current market price happens to be. Limit orders give traders control over execution price at the cost of execution certainty your order may not fill if the market never reaches your specified price.
HOW LIMIT ORDERS WORK
Buy Limit Order: You specify the maximum price you are willing to pay. Your order sits in the order book until the market price falls to your limit price or below, at which point it executes.
Example: Bitcoin is at $92,000. You place a buy limit order at $88,000. Your order will only execute if BTC drops to $88,000 or lower. If BTC never drops that far, your order remains unfilled.
Sell Limit Order: You specify the minimum price you are willing to accept. Your order sits until the market rises to your limit price or above.
Example: You own BTC at $92,000 and place a sell limit order at $100,000. It executes only if BTC reaches $100,000 or higher.
LIMIT ORDER VS. MARKET ORDER
Market Order: Executes immediately at the best available current price. Guarantees execution but not price you pay the spread and accept slippage.
Limit Order: Specifies exact price. Guarantees price but not execution the market must reach your price. No slippage risk.
MAKER AND TAKER FEES
Limit orders that sit in the order book and add liquidity are called "maker" orders on most exchanges, makers pay lower fees (0%-0.1%) or even receive rebates. Market orders that immediately fill against existing orders are "taker" orders and typically pay higher fees (0.05%-0.1%). Using limit orders instead of market orders consistently reduces trading costs significantly.
ADVANCED LIMIT ORDER TYPES
Stop-Limit Order: Triggers a limit order when price reaches a stop level combining stop-loss protection with price control. Time-in-Force options: GTC (Good Till Cancelled stays until filled or manually cancelled), IOC (Immediate or Cancel — fills what it can immediately, cancels the rest), FOK (Fill or Kill — must fill entirely immediately or cancel completely).
