[amibroker] How to use watchlistbits?

["cstrader232" <cstrader232@xxxxxxxxxxxx>]

I could use some help with watchlist bits: 

I get the syntax for adding a stock, and deleting it:

AB = CreateObject("Broker.Application");

st = AB.Stocks;

st.Remove("QQQQ"); 

st.Add("QQQQ");



But how do I add the stock to a watchlist?  

???

st.WatchListBits | ( 1 << 1);


tia!
