It would be nice if you could look into stocks from other markets as well. I'm from Brazil, so if you could make tickers from our markets work with the widget, it would be great.
Also, I think it's important to note that many companies trade in different markets. So, for example, if I search for "Petrobras stock", what would you show? The stock trading in NY, via the ADRs, or the stock trading in Brazil, the home market for the company? If you allow us to use ticker and market name it would be the easiest.
So PBR NYSE, shows the ADR value trading in NYSE, and PETR4 Bovespa, the brazilian value.
