I have added more than 5 tickers into a watchlist but only first 5 of them will be queried.

@wangyongliang Can you try to add more tickers to the watchlist? The backend database shows the watchlist has exactly 5 tickers.

I don't have this issue . I have a watchlist that has 9 tickers, and all of them are in the query.

Besides, the watchlist belongs to you. Other people will not have a message that shows it's an invalid watchlist.
