Order being rejected - Why??

[Josey]

I use IB and I've got an automated strategy that I have used with no problems. The other day I downloaded TWS build 895.3 and now my orders are being rejected with the following error message:

Native error='The size specified violates the size constraint specified in the default order settings. (383)'

My NT build is 6.2.1000.9

Is this a compatability issue or something else? If it's a compatability issue, which TWS version should I be using (I forgot the one I had) and is it still available for download?

Thanks in advance for your help.

Hello Josey,

Thank you for your post.

The issue is a compatibility issue because the current version of NinjaTrader that you are on (6.5.1000.9) does not support TWS 895. That version of NinjaTrader supports TWS 892.

However, we have a more current version of NinjaTrader (6.5.1000.13) which does support TWS 895, which you can download from the following link.

Thanks for your reply. I just downloaded the update NT program and now when I look for my strategy to backtest only 4 samples show up. I can see a number of strategies under My Documents/NinjaTrader 6.5/bin/Custom/Strategy folder, but only 4 Samples show up in the drop down box when I look to backtes. How can I access the other strategies?

Can you please compile your NinjaScript files and check if you see the strategies?

1) Open NinjaTrader
2) From the Control Center -> Tools -> Edit NinjaScript -> Strategy
3) Select any strategy and double click on it.
4) A new window will appear and you will need to right click and compile the strategy.

All NinjaScript files will now be compiled. Check if you see the other strategies listed now as well.
