Hello f.saeidi,

Thanks for your notes.

This question is unrelated to this forum thread about accessing Volumetric Bars data for secondary data series.

That said, you could use the Draw.ArrowUp() and Draw.ArrowDown() methods to draw an up arrow or down arrow on the chart.

See the help guide documentation below for more information.

Draw.ArrowUp(): https://ninjatrader.com/support/help...aw_arrowup.htm
Draw.ArrowDown(): https://ninjatrader.com/support/help..._arrowdown.htm

I suggested using the Strategy Builder because it is a great tool for setting up conditions or actions and clicking the 'View code' button to see the generated code used to create those conditions and actions in a NinjaScript. You could then copy the generated code for those conditions or actions into your custom NinjaScript.

For any other questions that may arise not related to accessing Volumetric Bars data for a secondary series, please create a new forum thread for the new question.

in script when rsi >70 i want to get alert and arrow up.
problem is arrow dont work correctly and when price change then arrow location change immediately.

Hello f.saeidi,

Thanks for your notes.

The condition does not have opening and closing curly braces so only the Alert() method is called when that condition triggers. The Draw.ArrowUp() method is being called on each bar update.

Add curly braces to the condition and place your Alert() and Draw.ArrowUp() methods within the curly braces to have both of those methods trigger when the condition is true.

For example:

if (rsi_m1 > 70)
{
    //call Alert() and Draw.ArrowUp() methods here.
}

When you pass in the same Tag name for the Tag argument of the Draw.ArrowUp() method, the draw object will be updated instead of a new draw object being created.

To have a new draw object be created each time the condition occurs, use a unique tag name for your Draw method. For example, a tag name of "Tag" + CurrentBar would be a unique tag name.

From the help guides linked in post # 48:

"tag: A user defined unique id used to reference the draw object.
For example, if you pass in a value of "myTag", each time this tag is used, the same draw object is modified. If unique tags are used each time, a new draw object will be created each time."

If a NinjaScript is not behaving as expected, such as drawing objects or not drawing objects as expected, you must add debugging prints to the script to understand how your logic is behaving.

Review the forum post linked below that demonstrates how to use prints to understand behavior.
