Hello @muktupavels! We understand your concern. To give you an update, we are glad to inform you that we already escalated this query to the relevant team and are awaiting clarification. Rest assured we will update you in this thread when we get information from the team.
Also we wish to inform you that although some features of Advanced Trade were already made public, please note that the team is still hard at work building all the remaining APIs and its corresponding documentation. Additionally, please note that the launched Advanced Trade API is in Beta which means that it is still in the stage of development.
Aside from posting to the Feedback Section of the forum, you may opt to engage in the Advanced Trade Feedback thread as we would love to know what you think about the newly launched Advanced Trade API. Thank you and we’ll keep you posted!
