AMZN half closed

#Earnings Bought to close half of my position, $AMZN Apr 26th 1885/1915/1945 #IronButterfly for 13.22. Sold yesterday for 28.15. Getting a bit nervous about this uptrend… I want to give it more chance to come back to 1915, but locking in nice profit on this first batch now in case it keeps going.
