Cant install an indicator

Hello Newtrader101,

As a first check, I would suggest following the instructions below to see if one of the already installed indicators is causing an error when it compiles.

• Open NinjaTrader
• From the Control Center select the New menu--> select NinjaScript Editor
• Right-click in the window and select Compile to compile all NinjaScript objects
• At the bottom of the NinjaScript Editor window, a new section will appear where you can find the error locations

If you are unsure as to what the error is indicating, please post a screenshot of the NinjaScript File column and Error column fully visible (not to be confused with the Code column)

• To take a screenshot with Windows 7 or newer I would recommend using Window's, Snipping Tool.
  • Click here for instructions

We have also collected more comprehensive steps for resolving NinjaScript programming errors in this tip in our Help Guide:

• NinjaTrader 8 - How do I resolve NinjaScript Programming Errors?

If the scripts compile without error, the next step would be to assess the indicator you are trying to import. As this error message generally means this indicator already exists, it would have to be removed prior to a new one being installed.

Custom NinjaScripts can be removed in one of two ways from within NinjaTrader 8:

• Add-ons can come as packages called 'assemblies'.
  An assembly can be removed by going to Tools > Remove NinjaScript Assembly > Select the assembly you wish to remove > Remove.
• To remove NinjaScript individually you can go to New > NinjaScript Editor > Double click on the 'Indicators' (or the relevant) folder > Right click on the add-on you wish to remove and select 'Remove'. Repeat these steps for all add-ons you wish to remove.

Please don't hesitate to let me know, should this not work or if you have any further questions!
