With TT Core SDK, you can create a separate application for each algo that you plan to execute. Or you can create a single application with multiple algos coded into it. Either way, you must also devise controls within each application to allow the user to manage the algos.
Or you can take advantage of the built-in mechanism within TT Core SDK that allows users to control the algos from TT’s front end user interface. Specifically, TT Core SDK provides functionality that allows you to build a TT Application Server which services requests from TT’s user interface to launch and manage the custom algos that you have built. This means that you can focus on building algos and leave the user interaction aspects to TT. It also means that users can launch and manage the algos that you have created in the same way as all other algos in the TT platform.
