MultiCharts: Trading Software for Automated Trading and Backtesting

Hi There,

I have a question. I understand that IB delivers there data as a "snapshot" every 0.25-0.3 secs. Basically sending what's changed since the the last snapshot 0.25 secs ago.

What happens if your charting compression is 1 minute and nothing changes (market goes quiet) for 3 minutes? Does that mean MC doesn't paint any new bars for 2 or 3 minutes. So the last bar was 2.05pm, market goes quiet for 3 minutes, then starts going again, next bar to paint is 2.08pm. Bars for 2.06pm and 2.07pm are non-existent as nothing changed during these times.

Does this make sense?

Cheers
Darren

TWS returns the last values not constantly but only if the value of the corresponding field is changed each 0.25-0.3 secs. That's why as soon as a certain value changes a new minute will be created with the timestamp equal to the local time.
