The type Ninjatrader.Strategy.Strategy already contains a definition for _indicator

[bigdavediode]

Hi,

Unfortunately, after attempting to import some ninjascript, we've received the following errors:

The type Ninjatrader.Strategy.Strategy already contains a definition for _indicator
The type Ninjatrader.Strategy.Strategy already contains a definition for BarsRequired
The type Ninjatrader.Strategy.Strategy already contains a definition for OnBarClose

And so on.

Tried removing all custom indicators and strategies and the error persists upon compilation. Also tried repairing the NT install. No luck. Is there an xml file to clean up?

Any thoughts?

Thanks,
B.

bigdavediode, would you mind contacting me at support at ninjatrader dot com with the file you're trying to import here so I could further check into? It sounds like it was maybe not made for your version of NT7.

Genetic Optimizer

Hi,

The file imported was the Piersh genetic optimizer ( http://www.bigmiketrading.com/ninjat...optimizer.html ) phgenetic, the latest version.

Deleting the Users\username\my documents\NinjaTrader 7\bin\Custom\Strategy\@Strategy.cs allows compilation normally, without errors. This is odd because this file appears to be restored upon repairing of Ninjatrader.

Does deleting this file fall into the category of "bad idea?"

Thanks,
B.

It looks like that script was exported with NT 6.5 and it then replaced your 7's @Strategy.cs which led to the issues, generally we would not advice touching the system indicators / scripts. NT7 would have per default a Genetic Optimizer, so I would advice checking into this first of all - I think the script was created initially as NT 6.5 did not have support for a GA.

I notice that it has recreated this file. Odd that the Ctrl-Panel->Programs and Features repair restored (what appears to be) the incorrect file.

Thanks for your help.

So you removed the script giving you issues and the installed @Strategy.cs and then run the repair and it would still result in a incompilable state for you?

[bigdavediode]

Yes, that's correct. All additional indicators and strategies were removed, @strategy.cs was deleted, a repair was run, (an incorrect?) strategy.cs was restored by the repair process, and the problem persisted.

However, just deleting the file allowed compilation to proceed correctly. @strategy.cs appears to have been regenerated. (Naturally we couldn't roll back the image on the VM because we had no snapshot. Don't ask, bracket-unhappy-face-bracket.)

The piers phgenetic optimizer was reported to work correctly under NT7, just not for us.

Thanks again for your help,
B.
