Hi,

Is it possible to change a chart's Period Value programmatically?

Hello maltese,

Thank you for your post.

This is possible but not supported. Here is an example using the mini Data Series window.

// check that the bars are Renko and that they are not at the desired 6 value
if(BarsPeriod.Id == PeriodType.Renko && BarsPeriod.Value != 6)
{
// if so, invoke the ninjatrader mini instrument selector which will change the period to the 6RE (6 Renko)
MiniInstrumentSelector MIS = new MiniInstrumentSelector(ChartControl, "6RE");
System.Windows.Forms.SendKeys.Send("{ENTER}");
MIS.ShowDialog();
}

Thank you for pointing me in the right direction. Would you know the constructor string for a 500 volume chart?

Yes, it would be "500V". You can find these listed at the following link under 'How to change a Data Series': http://ninjatrader.com/support/helpG...price_data.htm

Hello,

How could I set the "Chart Period Value" with code in Ninjatrader 8?

For ex: Change the chart time from 5 Minute to 15 Minute without a human mouse click or keyboard action.

Thank you!

Hello ninjo,

This concept would again be something which is not documented/supported in NT8. I would suggest searching the forum for other members who have tried to accomplish this and the routes they took. This is not something I would have a specific sample for, but is something which has been tried in the past. One search which brings up some results is " nt8 send keys".



I look forward to being of further assistance.

Hi Jesse,

I dont have problem with c# sendkeys. I need the function or method for set the "Chart Period Value" of the NT8 chart window via code.
Could you tell me a reference for it?
Thank you!

Hello ninjo,

This is not something which is documented, so I would not have anything additional that I could provide here. You would need to use key commands for the options you wanted if available. There is currently no specific NinjaScript way to interface with the instrument selector or interval selector.

https://ninjatrader.com/support/helpGuides/nt8/en-us/index.html?working_with_price_data.htm#HowToChangeADataSeries

To change an interval:

Type interval value plus the interval suffix (Value +suffix). Examples: "5M" for 5 minute bars, "100T" for 100 tick bars, "1D" for 1 Day bars,10 etc.

NT8 also uses a different window framework now so often the focus of the control in questions becomes a problem, it is not accurate to try and send commands to a control in this way. Assuming the

I look forward to being of further assistance.

Hi

I am trying this code and nothing happend:

System.Windows.Forms.SendKeys.SendWait("180M");
System.Windows.Forms.SendKeys.SendWait("{ENTER}");

If only try SendWait("180M"); then its works but the black overlay screen does not disappear...

Could you tell me how could I "Enter" the data of the chart time with code? Thanks

[ninjo]

I attach my basic example .cs as an indicator.

Test and then uncomment the next line and test again.

System.Windows.Forms.SendKeys.SendWait("{ENTER}");

Hello ninjo,

The SendKeys command is used for Windows Forms programs, this does not work correctly in WPF due to the focus in the windows and controls. This is what my comment in post #9 was about:

NT8 also uses a different window framework now so often the focus of the control in questions becomes a problem, it is not accurate to try and send commands to a control in this way.

You can see the Rollover Indications indicator that is on the public user app share for an example of managing focus and invoking key commands on a target control, that would be the only way that is known to work in NT8. https://ninjatraderecosystem.com/use...earch=rollover


Please let me know if I may be of further assistance.
