ScalperH Indicator

[dalecraw]

Hiya folks,

I have an indicator named ScalperH in my list. Somehow I downloaded an indicator which had the ScalperH indicator as part of it. I applied it to my chart, & there's a bunch of arrows on it. These arrows look like buy & sell signals, but they are always appearing late. Such as, the blue arrow appears after about 2-3 bars.
I also see a yellow arrow. I did trade this indicator on Sim today, & it did good for 2 trades.
Can anyone tell me more about this indicator? What do the blue & yellow arrows mean & how can I use it best?
I have included a screen cap to show what it looks like. If necessary I can upload the NinjaScript if someone can figure it out.
Thanx for the help.

Hello dalecraw,

If the indicator is open source (meaning we are able to read the code for this), please upload the code I will offer any assistance I am able.

However, I recommend you try and get in contact with the author of the script for more details.

Hiya Chelsea,

I tried to get ahold of the author by email, so far no reply.

I've included the Ninjascript in the attached text file. The forum wouldn't let me cut & paste it, as it's too long.

Thanx for the help.

Hi dalecrawl,

Exporting a script makes it nice and neat when posting on the forum as you will also have any dependencies needed included as well.

To export your script do the following:

1. Click File -> Utilities -> Export NinjaScript
2. Enter a unique name for the file in the value for 'File name:'
3. Select the strategy from the objects list on the left -> click the right facing arrow ">" to add the strategy to the export
4. Click the 'Export' button -> click 'yes' to add any referenced indicators to the export -> click OK to clear the export location message

By default your exported file will be in the following location:

• (My) Documents/NinjaTrader 7/bin/Custom/ExportNinjaScript/<export_file_name.zip>

Below is a link to the help guide on Exporting NinjaScripts.

Regarding the indicator, this indicator is mean to draw the arrows on past bars and does not seem to be coded to draw on the current bar.

DrawTriangleUp("MaybePivotUp",true,ExtremeBar,Extr emeBarLow-TickSize,Color.Red);
and
DrawArrowLine("AU"+CurrentBar.ToString(),true,Extr emeBar,Low[ExtremeBar]+TickSize,ExtremeBar,High[ExtremeBar]-TickSize,ScalpBarBrush.Color,DashStyle.Solid,Width ); //

Basically the indicator goes through the data and finds an extreme bar and marks it.

Hiya Chelsea,

Now I have an error message happening when I try to export. Can you tell me how to resolve it? Please see attached.

Hello dalecraw,

Thank you for your response.

Please follow the instructions below to see where the errors are coming from after compiling the indicator. This will allow you to debug the indicator/strategy or remove it from your PC. If you are wondering why you receive an error when compiling only one indicator, it is because NinjaTrader always compiles all indicators and strategies - not just one. This is done to give you the highest runtime performance possible.

• Open NinjaTrader
• From the Control Center select the Tools menu--> select the Edit NinjaScript menu item--> select Indicator
• Select any indicator and double click on it (we need only to open and compile one script to see all compile errors for all files).
• A new window will appear and you will need to right click in the window and select Compile to compile the indicators.
• At the bottom of the window a new section will appear where you can find the error locations.
• From there you have the option to comment out offending code sections, remove the complete indicator or debug it to be able to compile again.

If you are unsure as to what the error is indicating, please send me a screenshot of the error with the name and description fields clearly readable.

To send a screenshot press Alt + PRINT SCREEN to take a screen shot of the selected window. Then go to Start--> Accessories--> Paint, and press CRTL + V to paste the image. Lastly, save as a jpeg file and send the file as an attachment.

Are you kidding me??? It's this complicated just to get rid of a simple error?

I get the same error message when I try to delete the last few indicators I installed.

I'm gonna need a simpler solution.
