Thomas,
Thanks that was helpful. The RequestTimedRefresh did the trick, however had
to create a chart for each instrument. As for the speed, it seems to be able to
keep up (sql calls take a fraction of a millisecond). Though it should, metatrader
worked really nicely (kind of miss the open, run, close, and only new bars calls),
but didn't had an ib interface.
Am still running into trouble for it seems that the indicator is being called all the
time, not only when there is a new bar (sometimes hundred of times for each
timestamp). Do the value of the current bar keep changing while it is being
formed, and that is why the indicator repeatedly called for the same timestamp?
Thought of using RequestTimedRefresh(15,false), but am afraid that it would
miss the last values, if the bar is being updated during the time period.
Will be looking at a activex program, once I finish everything else. Most of the
development environments I had didn't like to do java. At least now I am able to
concentrate on getting something working, and not on how getting the data
stored.
Thanks again
