Hi,  
  
I’m getting my signals via the ATI API and my own client. Usually it works fine, except for a trade this morning for [LINKSYSTEM\_37780234]. The problem is that the API never sent me the closing trade signal.  
  
  
  
Sequence of events:  
  
\* Around 8:09am I poll the API and get a new signal with sigId=52933541. I confirm to C2 and C2 acks my confirmation.  
  
\* A couple of seconds later I report my fill to C2.  
  
  
  
20100915 08:09:24 Reporting MY execution for signalId=52933541  
  
CMD = [http://74.220.20.155:7878/?cmd=mult2fillconfirm&session=5293315396738176076&h=](http://74.220.20.155:7878/?cmd=mult2fillconfirm&session=5293315396738176076&h=)\<my host here\>&filldata=52933541sep2sep4599sep130.19&live=0  
  
  
  
RESPONSE =  
  
\<collective2\>  
  
\<status\>OK\</status\>  
  
\<error\>  
  
\<code\>0\</code\>

\<data\>  
  
Multiple fill confirmations (0) received for person 42774773  
  
\</data\>  
  
\</collective2\>  
  
  
  
  
  
Is it weird that there’s a (0) in the C2 response? Does that mean C2 got 0 confirmations? I double checked my syntax with the C2 ATI PDF manual and it’s not obvious to me why it is wrong.  
  
  
  
\* Around 12:30pm I should have gotten the exit signal with sigId=52944788 but that never happens. I only get notified that the entry signal is completed.

I guess your forum software striped out the vertical bars from the URL for the execution confirmation. But I put them in the right places as indicated in the PDF manual …
