IB-Interactive Brokers Daily Interruption

[SteveB]

I am trying to figure out how best to handle situations where Custom NinjaScript Strategies are cancelled due to disconnects from IB in the case where there exists open positions or orders.

I currently maintain an array of Open Orders, Positions and iOrder objects; I would like to completely recover when restarting my Strategies.

I thinking of maintaining a copy in a text file which I can input on startup.

Does NT's database maintain/resync with IB at Connection time?

If I reconstruct my array from the text file, will the original Tag names and recontructed iOrders be valid?

Will I get Fill events for any executions that happened during the down time?

Anything else I should consider?

Thanks!

SteveB,

What you may want to use is the OnConnectionStatus() to handle the strategy when you lose connection. You could try using RealtimeErrorHandling set to TakeNoAction and then you will be able to manually handle everything within OnConnectionStatus(). Bear in mind there are huge implications with using RealtimeErrorHandling. You will be completely on your own and you should code for every case possible. If your strategy hits something unexpected NinjaTrader will not try to save you with conservative position management actions so use with caution.

Could you provide some details for "every case possible"?

Thanks!

SteveB,

I could not. There are just too many possibilities. You need to be aware of the dangers of using such a method. Everything from overfills to order rejections; you need to handle them in your code. This is why using such a method should only be used if you absolutely know what you are doing.

Hello SteveB,

If you want to go around the daily interruption, you could start TSW via IBController. This program will automatically update the reset time, so you are effectively never being reset.
I start TWS with a batch file containing:
java.exe -cp C:\JTS\jts.jar;C:\JTS\pluginsupport.jar;C:\JTS\jco mmon-1.0.0.jar;C:\JTS\jfreechart-1.0.0.jar;C:\JTS\riskfeed.jar;C:\JTS\jhall.jar;C:\ JTS\other.jar;C:\JTS\rss.jar;IBController.jar -Dsun.java2d.noddraw=true ibcontroller.IBController IBController.ini

The ini file contains the account details.

This will of course not prevent you from other interrupts.

Hope this helps

I just installed this but I'm not sure how you run it. I run the exe but I get a gui app and I can't see how to start TWS. Can you please give me some more details?

TWS resets on me all the time and often bombs ninjatrader. I was seriously considering switching to another broker because of it but it sounds like ibcontroller will solve my problem.

Hello Cunparis,

I followed the instructions in the readme file, and I cannot remember I had difficulties.

So you need to update the following 2 fields in the ini-file
IbLoginId=abcde123
IbPassword=zz136>=?

abcde123 is you ib account name (the one you enter when logging on)
zz136>=? is a password. This is not the password you nomally use, but an encrypted password.

To get this encryped password, you run the following (in a command box: run cmd)
java -cp IBController.jar ibcontroller.IBController encrypt <password>
where <password> is your real IB password.
The output of this statement is the encrypted password.

Then run the statement I mentioned in my previous post. Be sure that the ini filename is the same as the one you edited.
The directory where IB controller sits is C:\IBController
It expects by default that TWS is installed under C:\JTS
(again, check the readme.txt that got installed in C:\IBController as well)

Hope this helps.
