Hi

When I am tring to connect TTAPI provider in OpenQuant, I am facing this error:



My OpenQuant and TTAPI is 32-bit. QuantRouter can connect with TTAPI provider.

Can you help me with this?

Thanks

Hi,

You need to install TT API package 32bit from TT web site (not 64) in order to use it with OpenQuant.

Getting a similar error message while trying to connect to the TT API. Using Windows 7 64bit, X_TRADER Pro 7.17.84.7, TT API 7.17.84.2 64bit and the OpenQuant 2014 trial. It won't work. Please help!

Hi,

we've checked TT API with OQ 2014 and it works fine on our side, so it looks like there are issues with your TT x32/x64 setup. I suggest you check your TT installation.

We will be back to you later today with more hints.

Thanks for the response Anton. Reinstalled everything but still no luck.

Hi,

it turned out that OQ installs TT dlls in OQ Program Files, so that these old TT dlls conflict with your newer dlls from TT setup. We will fix this next week but meanwhile you can try to replace these two dlls in OQ program files with dlls from your TT setup. You can also try to copy all dlls from TT setup to OQ program files.

Regards,
Anton

So I copied the dll files (TradingTechnologies.TTAPI.dll && TradingTechnologies.TTAPI.Tradebook.dll) from TT into the OpenQuant 2014 folder. It no longer gives me that error but now it just attempts to connect for awhile then crashes the software.

We've updated OQ2014 install. You can download it from standard location. Try to reinstall OQ2014 and make sure that TT dlls are not in OQ / program files any longer.

Thanks,
Anton

So now when I connect the TT API provider I get a green light. But when I add an instrument to Quote Monitor the program crashes. Got this output from Visual Studio...



Also, there are a handful of message boxes that appear on launch that say "This assembly is protected by an unregistered version of Erziz's ".NET Reactor"!".

ok, good to hear that now you are able to connect at least. It would be helpful if you tell us what instrument are you trying to add (with properties) so that we can try to reproduce/

Usually you can request instrument list from TT / Instrument provider and then use these instrument definitions, so that you don't need to set up instrument properties manually...

The instrument was CL. I had entered it manually.

Exchange: CME-A
Factor: 10
Maturity: 8/1/2018
Price Format: F0
TickSize: 1

We've fixed Eziriz stuff, update is on the download site. Will look into TT symbol settings.

Have you tried to get instrument definitionas directly from TT provider in OQ by the way?

I was able to get the instruments from the TT provider. I see the format has changed. Now to see if I can do some test orders...
