Google Finance uses it's own custom chart solution, not the Visualization API. If you are using the Viz API Query object to fetch data for you, then you can use the #setRefreshInterval method to update your data automatically. If you specifically want to fetch only new data since the last query, that is a bit harder to implement, but is doable.
