Rules based trading - Taking profit on Ezion

Ezion hit my profit target of 50% yesterday.  I longed on 3rd Dec 2012.  See the Entry on my blog.

Based on rules, I sold this morning at $2.18.  I did feel the emotions of greed whispering to me to hold on further.  Managed to brushed off the temptations and focus on obeying rules.
Admittedly, it was helped by Ezion forming a shooting star yesterday on the daily chart.  In addition, the price is now at the top of 2 channels.
Will I be buying Ezion again?  Yes, I may.  It is still a fundamentally sound company, and rising in momentum.  Again, if ever I trade Ezion again, my job is to ensure that the entry will be based on rules.
