Limit Order vs Market Order for Options

A limit order sets the maximum buy price or minimum sell price, while a market order prioritises execution over price. In the article, limit orders are preferred for options when price control matters, especially where visible size is limited or spreads are wide.

A limit order tells the market the worst price you are willing to accept, while a market order seeks immediate execution at the best available prices at that moment. The article’s liquidity framework strongly favours limit orders when price control matters because options can have meaningful bid-ask spreads and thin displayed size. OIC is cited for the point that market orders can move through available bids or offers if size at the best price is limited, which can make fills worse than expected. In practical terms, this means a theoretically sensible strategy can become unattractive once entry and exit pricing are considered. Within the playbook, the default operational habit is to use limit orders, record expected versus actual fill quality, and treat execution cost as part of strategy selection rather than an afterthought.
