Genesis' GTAPIB has bugs -- Does anyone actually use this thing?

I'm on standby waiting for tech support to respond so I'm posting here. The reason I'm posting here, of course, is because trading day time is limited for software development since they have no test servers. I want other developers to save time and possibly look at this later for reference. (Or, you know, they can assist me. :-)

That being said, I think there is a bug in their library. Their protocol document online says that the client library is supposed to send:

0x0002, 0x0008, 0x0111, 0x0101, 0x0000, 0x0000

These are all 16-bit quantities transmitted in little-endian order. However, when you actually inspect the wire, the GTAPIB library is actually sending:

0x0002, 0x0008, 0x0110, 0x0101, 0x0000, 0x0000

So either their documentation is broken, or their library is broken. The server then eventually disconnects me. Its second response calls the 'connect event' callback to be called and that's it.

Are there more issues with the library, and am I wasting my time? I get the feeling GTAPIB is not used very often and is very neglected. Is someone else out there using one of their other APIs with greater success?

Fortunately, I only intend to use this API for reading data and not placing orders. I'm wondering, however, if there are bugs in their order placement code and whether or not that even works as advertised.
 
No one else seems to be responding so I'll come out of the woodwork. A small group of us have developed a system using their API that has been running live for the past few months.

I can't solve your problem, but at least I can let you know that it does work.

Which API? GTAPIB, or their C++ library?

I'm getting an OnConnect() event twice in a row. The first one says things are ok, then I get a disconnect.

I should also mention that if I compile and run their sample, it also doesn't work.

This is why I want to know if you're using their other API. They claim to have three libraries, and some are less full-featured than others.
 
Looks like their C++ library works but their GTAPIB doesn't. What an oddity. At least I have something to work with now.

I dug this thread out just because now I'm suffering with the same problem, by using GTAPIB.

any expert has any comments about it?

look at the login log of my system pls:

:confused: :confused:
 
Two things:
1) what is the difference between the two libraries anyway ?
IOW why use the GTAPIB in the first place ?

2) has anyone gotten STOP orders to work inconjunction with placing bracket orders via their API ?
Last I heard was that it doesn't work...it returns an error message.
