Need help with Hourly Open Script

[AceHorse]

Hello everyone,
I am trying to create a script that plots (each) Hourly Open horizontal lines on the chart. I am no expert in coding and looking at various scripts I put together this script. From original 55 errors now, down to 1 and I don't understand what else to do. Can someone help me fixing this error? Thank you so much!!

Error:
HourlyOpen.cs The name 'DashStyleHelper' does not exist in the current context CS0103 56 120

Hello AceHorse,

As a tip, to export a NinjaTrader 8 NinjaScript so this can be shared and imported by the recipient do the following:

1. Click Tools -> Export -> NinjaScript Add-on...
2. Click the 'add' link -> check the box(es) for the script(s) and reference(s) you want to include
3. Click the 'Export' button
4. Enter the script name in the value for 'File name:'
5. Choose a save location -> click Save
6. Click OK to clear the export location message

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

• (My) Documents/NinjaTrader 8/bin/Custom/ExportNinjaScript/<export_file_name.zip>

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

It looks like you have modified the default using statements. We recommend that you create scripts using the NinjaScript Editor so the default using statements and structure is correct.

Please try copying over the default using statements.
