I would like to copy trades from one instance of Sierra Chart to another and thought that a study using a TCP or websocket connection to listen for new trades would be the best way. Is it possible to do this? What is the lifecycle of a sierra chart study? I figure I can always use polling with the built-in http request function as a workaround but that doesn't seem great.

Yes you could do this, but you could not utilize asynchronous notifications when data has arrived.

I am interested in achieving the same, and was considering using a websocket client in the Study that could consume trading signals coming from the websocket server. I am curious to understand: why wouldn't the study be able to use the trading signals it receives? Is it because the life cycle management of a Study can not be mixed with asio threads?

I actually haven't implemented websockets yet, but I assume they mean that the orders will not be placed in response to the websocket message without first being read during the regular study update cycle. Polling with their built-in http request is sufficient right now for me, but I would do a buffered websocket client with UpdateAlways and a chart update interval as short you you can.

How you develop this is up to you. The only point is that a custom study function is called by Sierra Chart and not by another method. However, when the custom study function is called by Sierra Chart, it can be set to Update Always at the Chart Update Interval, then you can access the data by whatever means that you want at that point in time. Yes exactly: but I assume they mean that the orders will not be placed in response to the websocket message without first being read during the regular study update cycle.
