Help Developing Average Price Points Indicator

[mlprice12]

Hi all,

I want to develop a very basic indicator that draws a horizontal line on the live chart based on the following criteria.

When: Starting at session open after every X bars (resetting at session close)
What: The average price of the previous X bars

Distance of horizontal line drawn should be equal to number of X bars chosen.

All X variables should be equal.


For example, 5 minute chart, X bar variable set to 12, instrument ES


I would want the indicator to start running at 6pm eastern (session open) and after the first 12 bars (1 hour) a horizontal line stretching right the length of the next 12 bars will be drawn at the average price of the first/previous 12 bars (6 to 7pm) I would like the indicator to continue to run until session close drawing a new horizontal line every 12 bars.

All horizontal lines should stay visible.


I'm watching videos and looking at other indicator code as guidance, but I am having a rough time writing my own code.

Could someone help me get started?


Thank you so much,
Mark

Welcome to the forums mlprice!

If you are new to NinjaScript and drawing with NinjaScript, I may suggest using the Strategy Builder to generate syntax to draw on the chart. You can click View Code to see the generated C# code.

Strategy Builder 301 (publicly available) - https://www.youtube.com/watch?v=_KQF2Sv27oE

Once familiar you can reference further drawing overloads in the Help Guide.

You will want to use Draw.Line to draw a horizontal line over X number of bars since Draw.HorizontalLine creates a horizontal line that does not end.

Having something done every 12 bars would be done most easily using the modulus operator (%.) For example, you could create a condition like:

if (CurrentBar % 12 == 0)
{
// Do something here
}

and this action would be taken every 12 bars.

The indicator can be applied a data series with your desired Trading Hours template to have the indicator only operate between certain time frames. You could also consider adding time checks within the code.

We look forward to assisting.

Thanks for the assistance Jim,

I will continue to try and write the code and will post back with more questions as they come up.
