# Bundle Mode ### What is it? Bundle Mode allows users to: * Bundle multiple trades, to be simultaneously placed as orders. This is especially useful for hedged trades, like the basis trade. * Test margin requirements of different portfolios before executing. ### How does Bundle Mode work? You add orders to a bundle. These orders are all placed (but not necessarily filled) simultaneously. You can set fill conditions on a per order basis in the bundle. It is especially powerful programmatically, because you can add other operations outside World in the atomic bundle. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
