Referencing Volume Question

[futurenick]

Hello,

I want a solution to print the volume of the last 5 bars and the average vol. of these Bars in the Top Right Corner of the Chart.
This was my solution. But the volume Numbers are not right. So there is a error in referencing the Volume and Displaying the Numbers of the Chart.
Maybe you have some suggestions?

Kind Regards, Nick

Hi futurenick, thanks for your post.

You are accessing the volume values correctly. Place a current bar check at the beginning of OnBarUpdate to ensure there are at least 5 volume slots to check e.g.:

OnBarUpdate()
{
    if(CurrentBar < 5) return;
}

Please let me know if I can assist any further.

[futurenick]

Hi Chris, Thank you very much for your help. I integrated your suggestion and it looks much better. But look on the screenshot. Bar -1 is not there. It is a litte bit weird but one more idea is needed.

Thank you, Nick

Hi futurenick, thanks for your reply.

It looks like you have identical tag names "teste1". Make sure all of the tag names are unique and you should get a text print out.

Best regards.

Hi Chris, you have a sharp eye ;-) Thank You.

I rearranged everything ab bit and included the Spread of the Bars. Do you know a way to format the strings a bit better, like Rows maybe?

Hello futurenick,

Thanks for your post.

"\t" can be used for tabbing in a string, but if you want more direct control over where the text is drawn, custom plotting can be used to do so. This is goes beyond the level of support that we provide for NinjaTrader 7, but you can reference the CustomPlotSample indicator and the Pivots indicator for further direction on how custom drawing can be done in NinjaTrader 7. GDI+ graphics would be used here.

Please let us know if you have any questions.

[futurenick]

Hello Ninjatrader, is there a possibility to check the script performance or the chart lag in NT7?

[NinjaTrader_ChrisL]

Hi futurenick, thanks for your post.

Not really anything in NinjaTrader 7 that can be used for performance profiling. In NinjaTrader 8 we introduced the NinjaScript utilization monitor where a print out of the total resource time of all NinjaScript objects is displayed:

Kind regards.
