Can someone explain this sentence: When connecting to the DTC Protocol Server in Sierra Chart using a websocket connection from a web browser, it is necessary to install a valid TLS certificate for the domain used. Both the private key and the certificate need to be placed in the /ServerCertificate folder within the Sierra Chart folder. The file names need to be: TLSCertificate.key, TLSCertificate.crt. coming from this page: Data and Trading Communications (DTC) Protocol Server: Web Socket Connections When I open a webpage on 127.0.0.1, what kind of certificate would Sierra need then? And let's say I created a special site dtctrader.com or something and try to connect to Sierra from there, would Sierra need a certificate for dtctrader.com? Can this be self-signed or would the browser dislike this...
