Limit orders cannot complete if you do not have enough tokens in your wallet to swap as you intended.
If you do not have enough tokens in your wallet, then the limit order will be canceled.
Limit orders that are automatically canceled due to a lack of tokens do not incur a network cost.
A limit order can also expire if it is not filled by the date you set when you submitted the order.
Expired limit orders that are not executed do not incur a network cost.
