Development Question: Non-Server Based Detailed Symbol Mapping

[heikenashi1]

Specific to development:

Where in the application are the symbol maps stored and how can developers programmatically update the symbol maps for various data providers including that of addons?

Hello heikenashi1,

The Instruments (and settings such as the symbol mapping) is saved in the NinjaTrader.sdf database.

Unfortunately, there is not any supported access to read or set these from NinjaScript.

Thank you Chelsea. Ninjatrader Developers will appreciate growing support for this years down the line - I work with many of them daily.
So your help now makes a huge difference!

Inside the MasterSymbols database table it's not clear or apparent where actual symbol maps for each provider would be stored for each MasterSymbol. please see below:

[Id] BIGINT NOT NULL,
[Currency] INT,
[Description] NVARCHAR(250),
[InstrumentType] INT,
[MergePolicy] INT,
[Name] NVARCHAR(50) NOT NULL,
[PointValue] FLOAT,
[PriceLevel] FLOAT,
[TickSize] FLOAT,
[Url] NVARCHAR(250),
[UserData] IMAGE,
[Version] INT,
[TradingHours] NVARCHAR(50),
[IsServerSupported] BIT,
[AutoLiquidation] BIT


Thank you so much Please Advise!


BTW:
Instrument2InstrumentList table clearly maps each master symbol to the insrrument list in a very clear, competent way, which is very well done by NinjatTader!!

Hello heikenashi1,

Access to the NinjaTrader.sdf file is not supported by NinjaTrader.

[moontrader1]

Can we send this to the developers as a feature to import the full maps initially?

[heikenashi1]

Hello heikenashi1,

Access to the NinjaTrader.sdf file is not supported by NinjaTrader.

Hi Chelsea, Good news is I don't think we need access to this or support for it in this context, because this feature is not implemented in the Ninjatrader.sdf

I went over it 10 times and with someone way smarter than me and there are no maps actually stored in this file. Please advise!

Hello moontrader1,

I will submit a feature request to our development for consideration. Once I have a tracking ID for this request I will post in this thread for future reference.

I'd like to plus one this vote! Please enable export also!!!

How are we supposed to be Ninja Traders if we can't go in and out with our symbols and lists?!?! :-)

[samsonli]

I use the NinjaTools Binance plugin and somehow this app has custom lists I couldn't find ninjatools studio on the NT ecosystem site but it looks like this guy found a solution. Good luck!

Thank you for submitting that.

Hello heikenashi1,

NinjaTrader considers the database proprietary and in general, and further do not want users accessing this to prevent platform instability.

ChelseaB, link removed.

NinjaTrader is the best, stay the best!!!!!

It's not just users but developers are intentionally blocked from this also. Based on logic is 99.99999% unlikely that a custom map would make the platform unstable because users can already edit this manually. We were initially misled. It is not even in the Ninjatrader.sdf so it is heavily controlled by ninjatrader servers side. This DRW thing has really got legs. This post is hidden from all updates on the home page.

The funny thing is that this would actually make a top story on redit!!!
