How to display "night market" graphic in IB TWS?

I mainly trade Hong Kong HSI and HHI futures. In IB TWS, its live data feed can still quote live data in "night market" time, but the graph stops updating after "day market" period. Anyone knows how to solve it?

 

There's a TWS setting for graphs showing data outside trading hours.

 

Ok I will try to find it thanks.

 

Open the chart for the instrument you're interested in, in the menu on the chart select Edit -> Chart Parameters. At the bottom there's a checkbox for Show data outside of regular trading hours.

 

yeah I just active it, thanks a lot!
