Stop macro when no longer receiving records for Exit output

Question

Is there a way to make an iterative macro stop running when there are no longer any records being generated through the Exit output?  Currently I'm having to set a Maximum Number of Iterations.  I don't know how high to set that number, so I'd like to just be able to exit the loop when there are no more records being received for output.

should the second step be done in the macro or in the workflow that I'm using the macro in?

I haven't used it on an iterative macro but the Test Tool (In the Developer Tools) is very handy for things like this:

First, in the Test tool configuration there is an options "Record Count Matches Specific Value" so if you chose that and set the test value to something like >= 1 then when the record count hits zero the test will fail.

The second step to this would be to go into your Workflow Configuration window--> Runtime, and check off the box "cancel running workflow on error". Hope this helps, let me know if it works!
