Hi, you do not need the source code for the news manager client as it is simply an assembly file, you just need to reference the file, you can do this from cTrader Automate or from Visual Studio, to do this from cTrader, just select the cBot and at the top choose Manage References, this will open a window, choose the browser button and find the ClickAlgo.NewsManager.Client DLL and select it, you should now be able to build the project.
You will find as part of your purchase you received the ClickAlgo News Manager product under license to install on two machines, we do not provide the source code for this, the NewsManager.Client is a different product and reads the news signals for the cBot.
