Mr. Cooper Group Inc. (COOP), formerly, Nationstar Mortgage Holdings, Inc, went public in March 2012 with an initial public offering. When we run a backtest after that date, it doesn't return any data.

We do have a map file for COOP:

$ cat coop.csv
19980102,coop,Q
20090619,coop,Q
20090630,coop,Q

which refers to a company that was delisted. If we run a backtest stating on 1998, we get a liquidate order due to the delisting.
