Undocumented/Unsupported Ninja Tips and Tricks

[r2kTrader]

This thread has been started to see if there is anyone interested in joining me to help start a Development Wiki, devoted to expanding Ninja in areas that are currently not supported or documented.

I will post some undocumented tips and tricks that you may find helpful. If you have one, please post it as well.

The idea is to use this thread as a starting point for the wiki. I may or may not actually do this, it will depend on the interest of the forum and others to help as I am a beginning programmer.

Please state if your tip/trick is for NT7, NT6.5.x or both.

Be prepared to experience the unexpected and be ready to resolve the unexpected as you use undocumented features

Have you ever wanted to load a workspace from within a strategy or when you start a certain strategy? Now you can. Just drop this line in your initialize() and change to your liking.

NinjaTrader.Gui.WorkspaceOptions.SwitchWorkspace("D:\\Documents and Settings\\User\\My Documents\\NinjaTrader 6.5\\workspaces\\123.xml", true);

If anyone is interested, you can use a similar technique to "auto-save" your workspace throughout the day.

Apparently NT has an FTP class for logging into a server and executing a series of commands.

This could be very useful if you want to provide your signals to a website for your subscribers.

It's found in "NinjaTrader.Cbi.Ftp"

There will need to be more work done on this, but I am going to work on a class that can be used to pump buy/sell signals to a pay for signal website. I know, I know, Collective2 or whatever, but this is your own and would run in wordpress and allow you to personalize the whole experience.

If there is an advanced programmer out there who would like to work with me on this project. Please PM me. I have the Linux boxes and a small hosting company and I know how to use OpenSource solutions to manage the other side of the equation. Namely taking the signal that is FTP'd to the server and putting it up on the website.

Again, please contact me if you want to help. This is a another example of how the development wiki could play a key role in helping provide starting places for people with ideas and needs, but that transcend the current limitations of support.

You probably don't need to use their FTP Class to accomplish this, but I just thought it was interesting. You could just as easily use any SFTP .NET library to poll a File that you streamwrite to, or even have a socket that you write to that is pumped right over.

This is a solution that would be used for a situation where you don't want to run NT on a windows server that also does the hosting. In my case I have Linux boxes (dedicated servers) and I would want to pump signals and results in realtime as well as Graphics images that provide a snapshot of the signal, etc.

You could also run your own little "Collective2" type service.

[UPDATE]
After some further thought, the ftp might be useful for uploading chart snapshots to your website. As far as real time signals, etc., it would probably be best to use a direct connection to a mysql database on your linux server (this post was primarily for those who use linux and want a bridge to get signals and the like from their NT strategies/indicators).

Here are some other options for TimeInForce you might want to play with.

Remember, none of this is supported by Ninja.

TimeInForce = Cbi.TimeInForce.Ioc; // Fill or kill
TimeInForce = Cbi.TimeInForce.Opg; // Order on Open (interesting??)
TimeInForce = Cbi.TimeInForce.Gtd; // Good Till Date (instead of GTC)

I recommend playing with these and of course testing before committing real capital. The one of interest to come clip traders may be the fill or kill.


Enjoy

This is a nifty little snippet.

Did you ever have the need to "Flatten Everything". All strategies, and all open orders. Just get flat!

NinjaTrader.Gui.SuperDom.SuperDom.FlattenEverythin g();

I tested it and it seems to work ok. It killed all my strategies and got me flat on any orders that work working. I mean it took me FLAT! And fast.

Test and use at your own risk.

Folls came up with a way of launching a windows form using a
windows strategy

http://www.ninjatrader-support2.com/...+Studio&page=2

I understand the form construction etc but can anyone show how to get information from ninja eg from a variable to the form. From what I can see Ninja is launching the form but no information is being transmitted.

What I am looking for is a way for ninja to produce a result from the on bar update method, and to transmit it to the form.

I am not expecting detailed code but an idea in principle would be welcome.

Great Thread but think the Ninja people should make it into a main thread,
ie underneath General Programming etc

MicroAl,

Since it is an old thread we will be leaving it there so people looking back for it won't get confused.

[MicroAl]

Sorry Josh some confusion I meant having a main Undocumented/Unsupported Ninja Tips and Tricks thread at the top of the directory so to speak.

You may find that Ninja gets extended in ways that even you people
never thought of

[NinjaTrader_Josh]

Thanks for the suggestion.

[r2kTrader]

Micro,

That was the purpose of this thread, so thank you for your comments.

Thanks,

Although not unsupported info, here is a discussion on serialization which can be helpful.
