BarsPeriod.Id for Unirenko?

[arbuthnot]

Hi Folks

If I want code to identify whether the chart is a tick, minute or any standard NT bar type, I can use code such as:

if( BarsPeriod.Id == PeriodType.Tick )

Now, there exist a few non-standard bar types such as Unirenko (available in this Forum for download, I think).

BarsPeriod.Id == PeriodType.Unirenko doesn't work so I doubt this is possible but is there another way of identifying Unirenko in code in a similar way?

Thanks in advance.

Hello arbuthnot,

You may need to use BarsPeriod.BasePeriodType and BarsPeriod.BasePeriodValue.

Below is a link to the help guide on BarsPeriod.

Thanks for your help with this, Chelsea.

I've thought of another approach. If I use only one non-standard bar type, i.e. Unirenko (after declaring a bool IfTime) I could code up something like this:

if (
BarsPeriod.Id == PeriodType.Minute
||
BarsPeriod.Id == PeriodType.Second
)
				
IfTime = true;
			
else
				
IfTime = false;

The 'else' here can only refer to the 'Unirenko' situation.

My question now is: it probably doesn't make a great deal of difference, but would it be better to keep this code in OnBarUpdate or should it ideally be in something like OnStartUp?

Thanks for letting me know.

Hello arbuthnot,

If this were in on startup the condition wouldn't be checked on every bar. The performance to check this is minimal and you probably wouldn't notice a difference, but in the end it would have less code to run on every bar update.

Thanks again, Chelsea, for your advice.

Much obliged.
