ADL Designer The ADL Designer provides the tools you need to design and test your custom algorithms. Major areas of the ADL Designer include: Toolbar: Menus and controls that provide access to algo and library management commands. Block Panel: Collection of functional blocks to add to your algo. Canvas: Work area for creating your algo. […]
After you begin developing an algo in ADL, you can save it at any point. When an algo has been tested, you can deploy the algo to make it available in Trade widgets, such as Algo Dashboard, Autotrader, and MD Trader. Once deployed, algos are available for execution until they are undeployed. Selecting Deploy from […]
Before beginning to design and develop your trading algorithms, you need to be aware of some basic concepts about algo design in ADL. ADL Designer presents an introduction to the interface you use to design, test, and deploy algos. Blocks provides an overview of the different types of blocks that ADL provides for creating your […]
Block types ADL provides a variety of block types that ensure you have the necessary tools to create both simple and complex algorithms: Trading blocks allow your algo to communicate with markets, including retrieving market data and status, getting trade data, submitting new orders and managing existing orders. Trading blocks primarily process continuously-updating data, such […]
A message is a piece of information that traverses the pathways established by the edges that connect ADL blocks. ADL supports two types of messages: continuous messages and discrete event messages. Continuous messages Continuous messages represent information that is continuously disseminated by an exchange. For instance, the bid quantity available at a specific price level […]
An edge is the line that connects an output port of one block to the input port of another block. Edges define how information flows through an ADL algo by identifying the pathways between ADL blocks. When a block’s output port sends a value, that value propagates to the connected blocks which can then use […]
A discrete event message occurs at a single point in time and can be used to capture market data at that precise moment. Discrete event messages have a key characteristic: when a block outputs a pulse of discrete event message, an algorithm temporarily stops channeling continuous messages from the exchange servers. Continuous message channels will […]
A user-defined variable is setting for certain blocks that lets the trader set a block value when starting an algo. User-defined variables help you create multi-purpose algos than can be configured dynamically and differently each time the algo is used. The following blocks can be designated as variable blocks: Bool block Instrument block Number block […]
