Simple Time Question

[davydhnz]

Hi,

I'm using a secondary data series to get a 15 minute series.

I want to calculate if more than 10 minutes is up on the current bar (which I'm calculating OnPriceChange).

What I want is, if the dynamic current chart time is more than 10 minutes of the close of the previous bar, do x.

Thank you!!

Hello davydhnz,

Thanks for your post.

You could consider using the AddDataSeries() method to add a secondary 10-minute data series to your script to use for your calculations.

For example, you could add a 10-minute secondary data series to the script and if this is the first added series then the script then you could create a condition that checks if IsFirstTickOfBar is true in BarsInProgress == 1.

This would check if the first tick of a new bar is processing which indicates the close of the previous 10 minute bar, meaning 10 minutes have passed.

if (BarsInProgress == 1)
{
    if (IsFirstTickOfBar)
    {
        //do something.
    }
}​

Hi NinjaTrader_BrandonH ,

I appreciate the reply, but the indicator is already on a 5 minute chart.
So the 15 minute calculations are the first secondary data series.

Any idea what to do in such a situation?

I was hoping I could go, if current datetime is > previous bar close datetime Time[1].AddMinutes[10],
but I'm not exactly sure how to do it.

Thank you!

Hello davydhnz,

Thanks for your notes.

If the primary series is a 5-minute data series then checking if Time[0] > Time[1].AddMinutes(10) would likely not become true since the current time (Time[0]) will only ever be 5 minutes greater than the previous bar time (Time[1]) since these are 5-minute bars.

You could consider creating a condition that checks if Time[0] >= Time[2].AddMinutes(10) which would evaluate as true since the Time[0] of the current bar would be equal to the Time[2] of the bar 2 bars ago (2 bars passed so this means 10 minutes passed).

Here is a reference sample you could view about manipulating DateTime objects which you might find helpful: https://ninjatrader.com/support/help...me_objects.htm

Otherwise, you could add a 10-minute secondary series to the script and use the secondary series to calculate logic as noted in post # 2. Or you could create a condition that checks if the current bar time of the added series (Times[2][0] if its the second added series) is greater than the previous bar time of the added series (Times[2][1]).
