Did KCG do a reverse split at some point?  It looks like in July perhaps?  I think I adjusted for that split making the 52-week low $8.11 instead of $3.67 which was the price when you alerted it.  I adjusted your alerted price based on the new higher trade split price.

Does this make sense?  Let me know if this did happen, I think I forgot to update the alert price on your individual page since it is still showing $3.67, hence the reason why the alerted gains is different between my screenshot and the results today.

Also keep in mind, that the alerted gains is a formula, so it will keep changing as new trading days happen, which is the reason I posted the screenshot, which I updated Sunday and took a screenshot Sunday.
