Hi
Backtester throws a run-time error when I place order for MCO (Moody's Corporation) on 29th September 2014.
I place order for a variety of securities in a loop (like always).
Also, If before placing the order I put a check, it works without an error. I am puzzled. Has anybody observed this before?
Thanks
Shiv
1.
order_target_percent(sid, 1) ....(throws error when it's MCO)
2.
if sid is symbol('MCO'):
log.info(sid)
order_target_percent(sid, 1) .... (this works) Try checking if MCO is in the data object. See https://www.quantopian.com/help#overview-checkingdata. Just a hunch. What is the exact error?
Good. It is basically a rule that you should always check that data exists before using a security key. The problem is that is not always done in posted examples. If you look at Delaney's example, https://www.quantopian.com/posts/quantopian-lecture-series-long-short-equity-algorithm, you'll see that he applies the check.
