Looking to build simple indicator -- need help

[lunardiplomacy]

Hello,

I am looking to build a simple indicator, the code for which I am hoping will also be simple. All I want is for the indicator to plot horizontal lines at two multiples of ten above and below current price. So for example if the exact price was 7182.25, I want the indicator to plot horizontal lines at 7190.00 and 7180.00. Or if it would be easier to do, simply plot multiples of 10 within a given range, i.e. from 7100.00 to 7200.00, what do you think?

P.S. I know that I can set up grid lines to represent exactly what I am talking about, however unless anybody knows a way to call upon grid lines in a strategy, that information isn't useful for me.

Thank you for any help you can offer, I look forward to your guidance.

Hello lunardiplomacy,

Thanks for your post.

If I understand correctly you want to draw 20 horizontal lines, every time the price changes.

To draw a horizontal line you would use the method Draw.HorizontalLine(): https://ninjatrader.com/support/help...zontalline.htm

You would need to use 20 different tag names so that as your code draws a new line it will delete the previously (no longer relevant) line.

You would need to decide how often you update the lines, if you truly want them to shift on every price change, then you would want to use the calculate mode of Calculate.OnPriceChange. Reference: https://ninjatrader.com/support/help...?calculate.htm

If you only want to update periodically, then you would need to decide how frequently to update and what price type to use for the reference.

If you always want to see all 20 lines regardless of price, then you would need to set your autoscale to true to include the horizontal lines in the charts autoscaling.

Hi Paul, thank you for your reply,

Yes, I think it's best to go with a range rather than use two horizontal lines at intervals of 10 above and below current price.

So, I think you are understanding... basically I would want 20 horizontal lines to be plotted at intervals of 10 within a price range of $200. So for NQ E-mini for example, I would want 20 horizontal lines, starting at 8300 and going up by $10 each time until 8500.

And, yes I would want to scale to price only so I don't have squished price action all the time, but I know how to do that already, good point though.

Would it be too much to ask of you to give a code snippet for what just one horizontal line would look like within that range? I don't understand how to connect plots/lines with logic/values.

Thank you, Paul.

Hello lunardiplomacy,

Thanks for your reply.

Here is an example as requested:

[I]protected override void OnBarUpdate()
        {
            if (CurrentBar == 0)  // Drawing it once on the first bar of data loaded
            {
                for (int i = 0; i <= 20; i++)
                {
                    Draw.HorizontalLine(this, ("HLineAT"+(StartPrice+i*10)), StartPrice+i*10, Brushes.Blue);

                }
            }
        }[/I]

I created a double type input called StartPrice that was used as the starting price.

I think what you want is the Magic Numbers indicator. Or something along that line. Feel free to edit it.
Have a look at this.

Ahhh, so there you have it. Thank you very much for that. At least now I know how to do it myself if need be, but this one you sent me is much more organized and put together, so I'm going to use it.

Thank you, Gorkhaan

Hello polo0202,

Thanks for your post.

I just downloaded and applied it to a chart, seems to work here (see attached). Do you see any error messages in the "log" tab of the control center related to the indicator?

[NinjaTrader_PaulH]

Hello polo0202,

Taking a closer look at the indicator, it appears that it is written for instruments with larger values. An instrument with a price value of less than 100 would not see many if any lines (unless you compress the price scale).

To see the lines on smaller priced instruments, you would need to rework the code provided by member Gorkhaan.

Thanks Paul, thats why i cant see it on Forex. Is there any free round numbers indicator?

Hello polo0202,

Thanks for your reply.

I am not aware of another indicator.

Have you looked at changing the charts' horizontal gridlines to meet your needs? This is an oft-overlooked capability that may be helpful to you.

In the price column of the chart, right mouse click and select "properties". Next change the "Horizontal gridlines from "automatic" to "fixed" Note that you can now adjust these lines on points, pips, or ticks basis and can specify the interval. Finally, on the chart itself, right mouse click and select "Properties" and in the chart properties you can adjust the visual characteristics of the gridlines.

I've attached two screenshots, the top one shows with the panel properties open, the 2nd with the chart properties open. Hopefully, this will help.

Hi, guys , where can i dowload Magic Numbers indicator ?

[NinjaTrader_BrandonH]

Hello hunterll,

Thanks for your notes.

You could download the MagicNumbers.zip file shared by Gorkhaan on post # 5.

After downloading the MagicNumbers.zip file, go to Control Center > Tools > Import > NinjaScript AddOn to import the NinjaScript onto your NinjaTrader 8 platform.

Or, you could browse the NinjaTrader Ecosystem User App Share linked below for a 'MagicNumbers' indicator or one that works similarly.
