When I use the tag attribute in an Order, the respective 'day' set of positions should also have the 'tag' attribute present while querying positions. But I do not see the 'tag' attribute documented here https://kite.trade/docs/connect/v3/portfolio/#positions. The 'tag' attribute is paramount to identify all open positions on a specific context. Without which, real time position's profit/ loss cannot be queried on a specific context (strategy).
There is no co-relation between an orderbook and positions. Positions is just a means to see your mark to market whereas orderbook shows the list of orders placed by the client. I am afraid we can't add tags for now. You can add it at your end.
