I've just encountered an abnormality with downloading M1 data through the FXCM real account feed:

I've been slowly-but-surely downloading M1 data for all the exotics, and I have not yet taken a closer look at them (ie, plot price curve is one thing I plan to do)... but sometimes it's obvious something is wrong by just looking at the filesize.

Overnight I downloaded another handful of pairs from 2002-2013 and I noticed two irregular-looking years for GBP/CHF. So what I did is I moved ALL those files for this pair to a subfolder and then restarted Zorro and requested loadHistory for only one of the bad years.

The result is that it now downloaded a seemingly-full dataset. This brings up several concerns:
Did the FXCM feed malfunction during the download process?
or did Zorro hiccup and cause this issue?

Here is the info I looked at:
(first run):
GBPCHF_2007.bar
739 KB
31496 min

(second run):
GBPCHF_2007.bar
8226 KB
350970 min

Note that the surrounding years (2002-2013) for this pair looked normal filesize, with the exception of 1 other abnormal year (2011).

EDIT: in re-attempting the (obviously wrong) years, I did get a more-normal looking file size for both years.
