what happens is you found a hole in the spike filtering routine :). If you open a chart on $TICKQ, SpikeFiltering is started for that symbol. If you have $TICKQ only as a compare to symbol on the chart, then it is not started. with $TICKQ, spike filter would filter out legit values. When you opened a separate chart for $TICKQ, that started the spike filter which stopped the updates on both charts
We have an Exclusion list for spike filtering, but there was a bug with that. I will have it fixed in next update. After that, you will want to add both $TICKQ and $TRINQ to the Spike Filtering exclusion list in settings.
