How to get diference of time between two bars

[Parmenides48]

Hello,
I try to create an indicator showing the difference in time between two bars.
Using the NinjaScript editor /New Indicator,

I only create two plots:
the Cero line ( named as "Cero" ), and Volatility bars ( named "Volat")


The only code that I write in the OnBarUpdate() is this:


protected override void OnBarUpdate()
{
if(CurrentBars[0] < 1 )
return;

Cero[0]=0;
Volat[0]= ToTime(Time[0])- ToTime(Time[1]);

}

And when I compile, there is a message of "Unhandled Exception.....

And then NinjaTrader8 is closed.
¿Where is the mistake??
¿How to get the time difference between two bars correctly??
Thanks.

I forget to tell that the bars I use are renko bars, not time based bars.

Whith this type of bars, the creation of each new bar, with explosions of high volatility, can be in less than a second, and I want to use that indicator as a filter, not entering trades when new bars are created in less than 1 second, because is not good idea enter with high volatility, stops can be hit very easy.

Hello Parmenides48,

Are you trying to get a difference in time between two bars or price? The code you have now is making a difference in time which is not something that you could plot. The difference between two bars in price would be:

Volat[0]= Close[0] - Close[1];

Hello,
I want to get difference of time, not price.
If time difference is in hh mm ss, and I cant plot it, how can I convert hours and minutes in seconds, and add all the seconds between this two bars. ?
What I want is to plot the total amount of seconds ( integer) , to see the "speed" of creation of every range bar.

Hello Parmenides48,

You would have to figure out what time value you wanted to plot, for example seconds. You can use the results TotalSeconds property

https://learn.microsoft.com/en-us/dotnet/api/system.timespan.totalseconds?view=netframework-4.8.1

(Time[0] - Time[1]).TotalSeconds

I am going to work on it.
Infinite thanks.
