I started developing for the C2ATI today. I’ve got a program which polls for signals and acknowledges them when they come in. Each response from C2 is logged.

I am getting opening signals from my test system but not closing signals. Here’s a log of what I captured in the interaction and some comments from me regarding what I think is happening:

```
# My code issues a GET on http://52.70.183.178:7878?cmd=latestsigs&session=30159301474515534667&h=myhost.example.com
# The result is a <signalpacket> with a signal id of 100592054; looks like I have successfully
# received the BTO issued by the system

```

From this point on, I don’t get any more updates about that position. So, my question is “Where’s my closing signal?” I would have expected a response to latestsigs with a and a of STC. The position is getting closed, but the C2ATI is never notifying my code with STC. Am I wrong to expect that?

Don’t forget to acknowledge the **fills** you receive on the opening portion of the trades if you want to receive the closing signals.

That worked. Thanks!
