On the TWS Pro Platform there are a lot of functionalities in this lesson you will explore the Hidden order attribute, which is available for a wide range of U.S. and non-U.S. products. It is important to understand all the useful things this functionality can do, for example, it allows you to submit large orders without revealing the full quantity to the market. This can be advantageous when executing sizeable trades to potentially minimize market impact and influence on execution price. Additionality from what you will learn on this lesson, you will also be shown two methods for creating Hidden orders within the Mosaic Order Entry Panel, so you can try the one that best fits for your strategy. Always remember to follow the standard submission process, so once you are done it can be shown on the Activity Panel with normality. Learning this you would be able to deal with large order sizes successfully.
