what should we call this bad luck or wrong timing

i don't get nervous if any of my trades hit stop loss i just get out of the trade and wait for the day to get over .i note all the trades in my diary and review the trades weekly or fortnightly.today also our trade of nifty 5000 put got stop loss hit but by the end of the day it made high of 148 all our targets got hit but we lost money as our stop loss was hit earlier . i am never afraid to book loss
