Market orders are attractive because they prioritize execution. The cost is that the final fill depends on order-book depth, spread and volatility at the moment the order hits the matching engine. Binance Academy’s slippage guide recommends splitting large orders to reduce price impact. Kraken’s Pro analytics page highlights order-book imbalance and 100k USD slippage as liquidity measures. Coinbase’s order-book explainer reminds traders that visible bids and asks are limit orders waiting to be matched.
Before sending a market order, check four items. First, compare the best bid and ask; a wide spread is already an execution cost. Second, inspect depth near the mid-price; if the visible size is small, a large order will walk through worse levels. Third, reduce size or use limit orders when the pair is illiquid, newly listed or moving quickly. Fourth, for perpetual futures, check funding, mark price and liquidation distance so a bad entry does not immediately weaken margin safety.
The same logic applies to exits. A stop order can protect discipline, but if it turns into a market order during fast volatility, the fill may be far from the trigger. Traders who need price control can consider limit, stop-limit, TWAP or smaller staged orders, accepting that better price control may mean partial or missed execution. The correct choice depends on whether the priority is getting out immediately or controlling average fill price.
