OnBarUpdate() on Range Bar chart

[dejavu]

Hello guys,

could anybody please explain.

I have the following code and my expected behavior would be to see black line on all price changes (because I use range to 1 tick) and it works in most cases except when data is coming very fast.

I have this code inside OnBarUpdate:

protected override void OnBarUpdate()
{
     Draw.VerticalLine(this, "vline" + CurrentBar, Time[0], Brushes.Black);
}

By first impression looks like NT doing rendering queue based on time and not based on price changes. Could you please explain?

Thanks

It looks like you have made it time based.

Change to barsago and use 0. That should work.

Hello dejavu,

I agree with sledge here. By using time there will be one object for that timestamp. Time stamps in NT7 are granular to the second, time stamps in NT8 are granular to the millisecond.

This means there will only be one drawing object for bars that share that same time stamp.

By using bars ago 0, you are specifying each bar instead of a specific bar by time.
