Unable to reference external library

[c.lim]

Hi,

I have NinjaTrader 8.0.9.0 and I'm trying to reference the Redis library. I used NuGet in Visual Studio to download StackExchange.Redis v1.2.6 which installed the Redis library to bin/Custom/packages/StackExchange.Redis.1.2.6/lib/net45/StackExchange.Redis.dll

I then used the following code in my NinjaScript

using StackExchange.Redis;
.
,
.
protected override void OnStateChange()
{
if(State == State.SetDefaults)
{
ConnectionMultiplexer redis = ConnectionMultiplexer.Connect("localhost");
}
}

Basically I'm trying to establish a connection with my local Redis DB. The code compiles fine in NinjaScript Editor. However, when I open up the indicator window, I do not see the indicator listed and I get the following error message in the NinjaScript Output window.

10/17/2017 23:13:57: Current State is State.SetDefaults
10/17/2017 23:13:58: Current State is State.Configure
Indicator 'SampleLevel2Book': Error on calling 'OnStateChange' method: Could not load file or assembly 'StackExchange.Redis, Version=1.2.6.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
Indicator 'SampleLevel2Book': Error on calling 'OnStateChange' method: Could not load file or assembly 'StackExchange.Redis, Version=1.2.6.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

Can you shed some light on how to resolve this issue please?

Thanks,
Clement

Hello Clement,

Welcome to the forums!

We do not provide support for third party libraries so the amount of direction that we may provide will be limited.

NinjaTrader 8 will require assemblies built with .NET 4.5 and these assemblies must have a reference added in the NinjaScript editor in order to function properly. These DLL's would have to match if you are using the 32 bit or 64 bit version of NinjaTrader.

My colleague Jesse has put a video together demonstrating how you can create an external DLL and import it into NinjaTrader 7. The same steps can be taken using .NET 4.5 instead to create a DLL compatible with NinjaTrader 8.

NinjaTrader_Jesse's post: https://ninjatrader.com/support/foru...91&postcount=4

Adding References in NinjaTrader 8 can be done by following the guide here: https://ninjatrader.com/support/help...indicators.htm

If these steps do not lead you toward a resolution, could you provide a minimal example of a NinjaScript that uses this DLL along with the DLL so I can test on my end? A barebones example similar to what Jesse has shared would be ideal for us to provide further input.

We look forward to being of further assistance.
