Buy/Sell in an indicator

I always thought this was not possible.
But it is.
Can anybody explain HOW it's done - even just the basic concept would start me off!

I'm not sure if this is what you are looking for but Rjay has modified this indicator to show bid/ask and level II.

It is in the download section of this site:

Download: jtRealStats_RJay_Pkg

There is a new NT7 compatible version (https://nexusfi.com/free_downloads/vip_elite_circle/) in Elite by Zondor (https://nexusfi.com/trading_member/zondor.html) This is a modified version of jtstats indicator also located here in …

Mindset,

Last trade price equals = Close[0]

Volume of last trade equals = e.Volume

You can do something like this.
------------------------------------------------------------------

int theAsk = e.MarketData.Ask.Price;

int theBid = e.MarketData.Bid.Price;

if (e.Price >= theAsk) VolUp == e.Volume;
else if (e.Price <= theBid) VolDown == e.Volume;

Sorry - when I say Buy/Sell I mean EnterLong /EnterShort commands.

never tried myself, but my guess is they are creating an OIF
(= order instruction file)
Ninja picks it up and fires away ....

You could try building some setups with strategy builder to see what the code looks like, then adapt it to your indicator?????

hmmm... why would you need that in the first place?
Isn't strategy based on indicator result good enough?

I have a basic set of "rules" that I like to trade but there is an element of discretion.
For instance if the potential profit is not enough I might pass on the trade altogether.

Secondly I can assess the trade with 2 or at most 3 mouse clicks - what I would like to do ( a la PositionSizer) is then be able to take those values and just pop in a buy/sell order with a target and a stop all on oco.

I can do it at the moment via a second set of charts ( strategies only) but that seems a bit lame - if NT provided a full and proper reference documentation it might be a whole lot easier!

The point of this thread is that up until I had seen position sizer - I didn't think it was possible AT ALL to get an order off from within an indicator. I have come from Tradestation ( 5 years ) and I must say "discovering" what NT can do and how to do it is very uneasy in comparison. I guess that is why this forum partly exists?

Plus I am wholly new to C# so sometimes it is all a little mysterious to me

toulouse - sorry what is an oif file - I have not heard of that.

here you go, straight from the horses mouth ..... errr just copied from the help pages ...

File Interface
The file interface uses standard text files as input. These files are called order instruction files (OIF) and have specific format requirements. NinjaTrader processes the OIF the instant the file is written to the hard drive and subsequently deletes the file once the processing operation is complete.

there�s much more detail on the help pages about the syntax.
If you know how to open and write to a file from within an indicator you can create orders.

Scary isnt it? lol

Right ... so looking a little deeper into this I see that Tradestation users a dll called ntdirect.dll.
But you can only use this from an external application - not from within NT?

I tried the following for instance and get a using reference error

Code

   NinjaTrader.Client.Client NTClient = new NinjaTrader.Client.Client();
            int myPosition = NTClient.MarketPosition(@"FDAX 12-09", @"Sim101");
            txtMarketPosition.Text = myPosition.ToString();

it wants using System.NinjaTrader.Client but that doesn't work.
