I’ve never tried to bring up 1-sec bars without tick data so I have no idea what will happen.

There are 3 basic bar types in NT that are used to construct all other bar types. Tick, Minute, Day. Every other bar type is constructed from one of these three.

If you look at the code for SecondBarType, you’ll see that the Second bar type is constructed from tick data.

			BuiltFrom		= BarsPeriodType.Tick;

So yes, you need tick data if you want to see accurate 1 Second bars.
