In options contracts, can market orders be entered in continuous trading without restrictions?

In options contracts, market orders cannot be freely entered in continuous trading without restrictions due to various factors including market liquidity and the need for manageable risk exposure. Continuous trading often requires specific conditions that must be met for a market order to be executed effectively. This could involve restrictions related to the bid-ask spread, available liquidity, and the potential for slippage, which is the difference between expected price and the executed price.

For example, in fast-moving markets or during periods of high volatility, placing a market order could result in significantly unfavorable execution prices. Additionally, exchanges may have specific rules that limit the types of orders that can be placed at certain times to protect traders from excessive risk that arises during certain trading conditions. Thus, the environment in which trading takes place imposes limits on the execution of market orders.
