When I select a stock from a quote list for charting display under say, the 30 minute interval parameter, the chart is first displayed with a last price that's substantially away from the actual last price of the time series. In order to clear this error another rate parameter, say, 10 minute, has to be chosen, and the erroneous entry is cleared. Then one can go back to the 30 minute without the error showing. Is this a bug or can I configure 1459 to eliminate the showing of spurious data?
