I would like to choose an expiry data for my orders, Actually if no one take my order I’m charged a fee to delete it. In my country there is a little to no volume and I’m afraid from putting a maker order because of this. So I hope it will help to incentivize maker orders and volume if orders can have an expiry date and delete them without having to pay the fee
An offer being published implies mandatorily that some mining fees are immediately consumed.
Deleting an order cannot bring you those fees back.
