I solved the problem.
Just re-install Multichart.
Thanks.

Hi TJ

Thanks for your help.

No matter what type style I choose, it showed no data on the chart.

Hi TJ

MC9 is Multicharts 9.
I did not change anything in QM or Multicharts.
Cannot get tick charts on other instruments.
I have no idea what's happened.

Hi,

I have tick data in QM (MC9).
But it cannot be showed in the chart.
What's wrong?
Thanks.
