Volumetric Bars - GetMaximumVolume

[AgriTrdr]

Hi,

I would like to find the maximum total volume in a bar at what price that occured and draw a line at that price. I'm using Volumetric Bars and found GetMaximumVolume:

https://ninjatrader.com/support/helpGuides/nt8/?order_flow_volumetric_bars2.htm

Print("Maximum Combined: " + barsType.Volumes[CurrentBar].GetMaximumVolume(null, out price) + " at price: " + price);

When I use this and compile, I get an error for price.

1. What would be the best way to find the maximum volume at price
2. How could I resolve the price error?

Thanks

Hello AgriTrdr,

If you would like assistance with an error message, please provide the full error message.

May I confirm you have declared a double variable named price?
The help guide page you have linked shows this in the sample code.

Please see the error message below:

Operator '>=' cannot be applied to operands of type 'string' and 'int'

Hello AgriTrdr,

Are you certain line 85 is this print with the call to GetMaximumVolume()?

May I have a screenshot of the error and line 85 showing in the NinjaScript Editor?

[AgriTrdr]

Absolutely. Please see the attached screenshot.

Hello AgriTrdr,

Your screenshot is not showing the error message as requested.

The print you have suggested is not on line 85.

The code on line 85 is:
if (POC >= UserDefinedVolume/3).

This is not related to the print you suggested in post # 1.

Also you are using var instead of defining objects as the actual type.

Either POC or UserDefinedVolume is not a number.

I see you are assigning POC to the string. A string cannot be compared to a number.

Were you trying to use if (price >= UserDefinedVolume/3)?

Were you trying to assign POC to the price variable?

Were you trying to assign POC to the price variable?

Would the "price" give me the actual price or the volume at price? A little confused on what it would provide. I'm trying to get the max volume within a bar, but also would like at what price that's occuring.

Thanks

Hello AgriTrdr,

The price variable is an out parameter. You are not assigning POC to the output parameter you are assigning POC to a string where price is converted to a string and concatenated with "at price:".

A string cannot be compared to a number. This is the same issue.

You can compare price to a number, because it is declared as a double, which is a number with a decimal.

If you want to assign POC to the value of price it would be:

barsType.Volumes[CurrentBar].GetMaximumVolume(null, out price);

double POC = price;

Thank you that worked.
