Tradestation Interface to Ninjatrader example

[Widgetman]

Hi,

I am trying to get a simple example working in easy language that will fire 1 order off through the ATI, and not send any more orders until that position is flat and there are no positions. Would anyone have a example I could look at which is written for easy language? Any help would be greatly appreciated.

Thanks

Did you look at the sample script provided with NT installation? See Help Guide.

Hi,

Yes I did try the small example provided. What I found was the example sent many orders which varied from 1 to 5 before the first order could get filled. Is there a way to tell the ATI to only send one order and a stop if it has another order pending ?



Here is a sample of what I tried



NotInTrade=NTMarketPosition("MyAcctId");

ifLastBarOnChartandNTConnected(1)and(NotInTrade=0)then



begin





Success=NTBuyMarket("",1); // Send Market Order

NotInTrade = 1; // Set Flag Immediately To Indicate I Sent An Order

Success=NTSellStop("",1,InsideBid-.0010); // Send Stop

end;

How about createa variable? I am no EL expert but in plain english:

var placed = false;

if (placed == false)
placeOrder

Well in the code snippet I showed earlier I have a variable called NotInTrade that is suppose to reflect the current position state. If I get a order filled it was my assumption that NotInTrade = NTMarketPosition("MyAcctId") would not return 0

This should stop theIF statement which checks for NotInTrade = 0from sending any more trades. I even went to the trouble of setting the flag just after I send a market order to a 1 which would stop the loop from firing again. I still see more than one trade from being sent and it also sends more orders on the next trigger condition even if I currently have some orders filled. Am I missing something here on how NTMarketPosition works ?

Widgetman,

My apologies. I just tested the script and experience the same results as you. I will forward to development for further investigation. NTMarketPosition() should return a value other than zero if not flat. We will have this resolved with our next update.

Hi Ray,
Thanks for all the help. I really would like to use your system to interface my custom trading system. Any ideas as to how long it would take to get fixed ? I also am a Engineer so if there is anything i can do to help with the testing process please let me know.
-Thanks

Thanks for the offer. Should be fairly straightforward to resolve. Likely have another update within a week.

Widgetman,

The problems I experienced were due to changes I personally made to the NTMarketPosition() function some time ago for testing purposes. The function works as expected.

Please reimport and override all NT functions. Import the ELD from C:\Program Files\NinjaTrader 5\bin\AutoTrade\NINJATRADER.ELD.

This will ensure that you have the correct functions. Then try the NT sample script again.

Hi Ray,
I downloaded the latest beta version off of your site last Thursday and re-installed it. I also have imported the latest ELD that was installed after running the beta. It is dated 12/21/2005. Is the the correct file I need to test ?

Hi Ray,
I also wanted to ask if there was a way to get a print statement in the easy language interface to show what the NTMarketPosition() value currently was so I could trace through the sequence, and see if I can actually see the value change from 0. Please let me know when you get a chance.
-Thanks

Sure, just add Print(NTMarketPosition("")); at thetop of the NTSample script.

Hi,
What is the date on the ELD file you have working ? I would like to make sure I am using the same one.

Hi Ray,

Can you tell me where I can get a copy of the newer version of the ELD. I just installed the beta version once again, and the ELD file in the bin folder/autotrade is dated 12/21/2005. Maybe you can post a link here to DL it. Thanks for all the help.
